Video Case Study

Repairs to Leaking Balcony – Restoration Project

  • Findlay-Evans, Melbourne based Certified Waterproofers & Registered Building Practitioner, provided a complete solution to permanently repair a badly leaking balcony and rooftop terrace.
  • The project involved both waterproofing remediation & balcony repair works to solve a challenging problem involving long-standing water ingress into structures.
  • Once structural repair & remediation building works were successfully completed by our team of carpenters, the Findlay-Evans Certifed Waterproofers then installed Liquid Applied Membranes (LAMs) – the Liquid Rubber waterproofing system – to the balcony surface.
  • To help provide a cost effective solution to the client, we recommeded that it was possible to re-use the existing pavers.
  • The balcony pavers were consequently installed on a buzon pedestal paving support system.

Waterproofing Method : Balcony Repairs, Building Works & Demolition

  • Substantial balcony restoration & rectification works were needed prior to waterproofing and paving installation using an adjustable support system.
  • Existing tiles and leaking membrane required strip off.
  • The pavers/tiles were reused, however the badly failed PVC sheet membrane was disposed.

The Findlay-Evans Team removed all pavers and stockpiled them for reuse.

  • There was an old PVC sheet membrane system which had shrunk back from all drainage points.
  • This shrinkage had allowed water to migrate down beside several drain pipes, instead of water flowing into the drainage system.
  • This was a major issue contributing to water ingress down the rooftop terrace.
  • So the remedial works also involved plumbing alterations to allow water to flow through and into the drain pipes, rather alongside the drain which was currently occurring.

The Findlay-Evans Team did a fantastic task of site clean up!

Waterproofing Application Using Liquid Applied System

  • Once the building site was clean, as the Findlay-Evans Team are Certified Waterproofers, installed a new waterproofing system over the entire area – Liquid Rubber Membrane.
  • Being liquid on application, the waterproof membrane has the ability to contour around utilities, penetrations, upturns and conformed to balcony/rooftop shape – the ideal waterproof system for balcony and rooftop remediation, repairs and restoration.
  • Our Balcony Restoration System consists of an inter-layer of fiberglass to ensure extremely robustness and longevity to the membrane method.


Preparation with tape detail along all joins and penetrations

Our Team detailed relevant areas thoroughly prior to waterproof application, ensuring the project was made permanently water tight.

Balcony Restoration & Paving Buz-On Installation

  • The air-conditioner system had to be rolled out of the way with the use of help of our air conditioning experts.
  • Then the Findlay-Evans crew re-installed the pavers on buzz-on stands.
  • Arma-Blue, a superior & robust protection for waterproofing systems, were used to isolate the pedestal stands from the membrane system.
  • These buzz-on stands can be screwed up and down to get the heights of the pavers correct.

Waterproofing Planter Boxes

  • Once we had all the pavers in position, our Team decided to waterproof and apply protection sheet to the planter boxes which were also a cause of water leaks.
  • The Findlay-Evans Team consists of carpenters and waterproofers, so we framed up the planter boxes and reinforced the capping and all floor and wall junctions.

Melbourne Waterproofing Contractor & Building Repairs

The principal contractor, Morgan’s Constructions, was pleased to have this part of the project as an end-to-end waterproofing & remedial building works managed & completed by Findlay-Evans.

Paul Evans, Manager/Director of Findlay-Evans Waterproofing, was pleased the results of an usual and challenging project.

Repairs to Leaking Fire Service Tanks

Maintenance & Repairs to Water Storage Tanks

If you’re a commercial property owner or body corporate, you need to maintain your fire service tank. Fire service tanks form part of the building infrastructure and are therefore the responsibility of the property owner.

The two main reasons we find causing leaking water tanks:

1. The most common cause of leaking tanks is the age of the tank.

2. Water leaks also occur due to ground movement and/or tank movement over time.

The Findlay-Evans Team apply waterproofing repairs to leaking Fire Water Storage Tanks

Liquid Membranes for Tank Repairs

Liquid Rubber is the ideal to waterproofing product to repair all types of water storage containments: Concrete, Steel and Polyethylene.

  • Liquid Rubber is a spray-on flexible seamless membrane.
  • Being liquid means the membrane will contour to any shape – ideal for tanks.
  • For concrete containment walls, Liquid Rubber protects the concrete surface from water, waterborne and chemical contaminant.
  • Its low permeability, excellent adhesion and elasticity make it ideal to prevent water damage and bridge stress cracks in concrete.
  • Liquid Rubber also adheres to any metal surface including low carbon steel, galvanized and rusted metal.
  • It creates a seamless barrier on metal surfaces and is an excellent guard against corrosion: both preventing rust on new surfaces and preventing further corrosion on already affected areas.
  • Liquid Rubber products are water based, solvent & Volatile Organic Compounds (VOCs) free, and cold applied to provide a seamless, high performance membrane.
  • Liquid Rubber is an environmentally friendly, “potable” and corrosion proofing waterproof product designed as protective coating for water storage tanks.

Best Waterproofing Product


Liquid Rubber – Rapid Application


Spray – On Liquid Applied Membrane

To determine which one is best for your specific tanked structure, consider the following:

1. How much does it cost for waterproofing repairs?

  • Labour-intensive waterproofing systems or those that are complex or time-consuming to install are generally more expensive.
  • Spray -on membranes have the distinct advantage of rapid installation, minimal disruption to the work site, saving time and labour costs.

2. How long do waterproofing repairs take?

  • Spray-applied liquid membranes is the fastest waterproof application – far more rapid than liners or sheet membranes.
  • No matter what system you use, preparation is a critical component for successful waterproofing and adds to the time factor.
  • Findlay-Evans Team are meticulous preparing all surfaces prior to waterproofing application.

3. How much design flexibility do liquid waterproofing systems offer?

  • Liquid waterproofing systems can be applied to either to the positive or negative side of a tank structure.
  • Application can be above or below ground, internal or external.
  • Liquid Membranes are eco-friendly and no VOCs – satisfy al OHS requirements and safe for confined spaces.

4. How durable is the waterproofing system and how long will it last?

  • Some systems have a finite useful life and will eventually crack, dry out or otherwise deteriorate, leaving structures vulnerable to water leakage and contamination while others are designed to last the lifetime of the structure.
  • Liquid Rubber products were designed to address the many problems encountered with traditional liner and sheet membranes.
  • New generation water based polymers are not only eco-friendly but will not crack, dry out , have seams and will last the lifetime of the structure it is protecting.

5. How much maintenance does the system require?

  • Some systems require periodic repair and maintenance to repair damage or cracking and maintain their effectiveness.
  • Others, like liquid waterproofing systems, have the ability to flex and move and bridge cracks over time, which can help reduce downtime and save maintenance costs over the life of the structure.

6. How well does Liquid Membrane systems protect against corrosion?

  • The corrosion of steel reinforcements by water and waterborne contaminants can significantly shorten the life of a concrete tanked structure.
  • Liquid Rubber offers proven corrosion protection.

     

7. Is the system certified non-toxic and safe for the environment?

  • This is especially important if your tank will hold potable water that could become contaminated by the inward migration of waterborne chemicals, chlorides, sulphates and silt.
  • Liquid Rubber is water-based and certified “potable” for human consumption.

8. What kind of guarantee does the manufacturer/distributor offer?

  • Always choose an applicator that stands behind the products they install.
  • Findlay-Evans Waterproofing are Certified Waterproofers and Registered Building Practitioner with the Victorian Building Authority (VBA).

How to a Repair Leaking Concrete Roof (Melbourne Case Study)

Remedial Waterproofing to Leaking Concrete Rooftop

Video – Case Study

Video below explains how Findlay-Evans Waterproofing rectified water leak problems for this challenging rooftop, which also involved difficult access for the Team and equipment.

Project: Badly deteriorated waterproof membrane causing water leaks in concrete roof slab

See More Findlay-Evans Waterproofing Case Study Videos HERE

Best Membrane for Concrete Roof Slab

Findlay-Evans Waterproofing recently completed a particularly challenging roof remedial waterproofing project close to Melbourne CBD.

As shown in the image above, the height and condition of the existing roof made access difficult.

However all our Team are “Working at Heights” & “Confined Spaces” compliant.

And our spray apply waterproofing system is mobile and easily transported to rooftops.

The Team successfully installed – on time and on-budget – a UV stable waterproof membrane on a concrete slab roof.

Prior to the new membrane, this rooftop had an extremely deteriorated existing polyurethane roof sealant that was causing quite extensive water leaks.

Preparing Concrete Surface Prior to Waterproofing

It is extremely important to prepare and clean any surface meticulously before applying a new waterproofing membrane.

Our Team had to complete extensive preparation to the badly leaking and deteriorated concrete substrate prior to spray-on application of a Liquid Rubber Membrane.

  • Our Waterproofing Team was the nominated waterproofing contractor to provide a permanent solution for a membrane to fix a leaking concrete roof for a commercial large flour mill.
  • While the actual roof substrate was still in good condition, the existing polyurethane membrane was in a very poor state allowing water to penetrate through the concrete roof.
  • To ensure a permanent waterproofing solution for this roof, we started off by removing the old defective membrane by using mechanical scrapers.
  • Once the deteriorated polyurethane membrane was removed, we then proceeded to cleaning the concrete roof to ensure a good adhesion for the new Liquid Rubber Membrane.

Waterproofing Method for Flat Concrete Roof

  • Although the existing concrete roof was in good order, in general there were some areas that required rescreeding and leveling out to create a sound roof substrate.
  • We went ahead and screeded these areas with flexible screed, and then coated with Liquid Rubber waterproofing membrane.
  • The entire concrete roof was coated with Liquid Rubber including an interlacing fiberglass mesh to make the membrane even more robust.
  • As this building was particularly big, there was a lot of movement and therefore Liquid Rubber was the ideal solution to waterproof this flat roof and stop water leaks.

Waterproofing Membranes for Retaining Walls

Posted on by Waterproofing Melbourne

Waterproofing for Retaining Walls

Waterproofing retaining walls, below ground tanking, foundations & basements require best practice waterproofing techniques.The consequences of water leaks due to basement membrane failure are costly and often difficult to rectify.


Basement Waterproofing

Liquid Applied Waterproofing Membrane applied for below ground tanking by Findlay-Evans.

Recent expensive lawsuits due to water damage from faulty construction techniques have raised the level of awareness about the importance of correct waterproofing.

Video – How Waterproof Basements

  • This is particularly the case for below ground waterproofing where the cost of failure is high.
  • Rectification works for leaking basements and retaining walls often involve extensive & costly excavation methods, complete re-installation of a new membrane and backfill once again.
  • Very often with below ground waterproofing failure, there are also property damage costs involved as well as the repair costs.
  • Obviously it is far more cost effective to waterproof correctly the first time – however below ground waterproofing in construction unfortunately is often a “out of sight” mentality!

Waterproof Systems for Retaining Walls


Retaining Wall Waterproofing


Liquid Applied Membrane

Using Liquid Spray On Waterproofing

Spray Applied Liquid Rubber

  • Liquid Waterproofing Membranes will conform to the shape of the wall & then extend down to footings/foundation in one seamless membrane.
  • Liquid Rubber is extremely flexible – the waterproof membrane will move contraction & expansion of cement block wall.
  • Spray Application is FAST – up to 3 x faster than sheet membrane waterproofing systems.

How to Waterproof a Retaining Wall

  • Selection of quality waterproofing product that will last the lifetime of the building.
  • Knowledge and understanding of problem areas of below ground structures – slab/foundation junction.
  • Retaining Wall Membrane – the best ones are Liquid Applied – which have flexibility and will move with the building.
  • And most importantly from the builder’s point of view -GOOD RETAINING WALL PREPARATION

     

Preparing Retaining Walls for Waterproofing

Preparation is vital to prevent water penetration for below ground structures.

  • Quality waterproofing is all about preparation.
  • Great preparation is all about attention to detail.
  • For below ground that means preparation to all voids, form-tie holes, and joints in the structure.

Video – Spray On Liquid Waterproof Coatings

From a builder’s/developers perspective, here are a few preparation pointers to achieve successful waterproofing.

  • Waterproofing products DO NOT adhere to a dirty surface.
  • Scrape off excess and loose material from walls and footings and power wash before waterproofing applicators arrive.
  • Get as much as possible done ahead of time: once waterproofing application starts timing is crucial and to stop to scrape loose concrete from the footings etc etc interrupts the rhythm.
  • Keep the foundation wall and footings clean, free of loose material, and fairly smooth just before waterproofing.
  • Remove concrete form ties. If there’s an odd form tie that wasn’t aligned properly and won’t break off flush, cut it off with a cutting torch or reciprocating saw. Break form ties off on the inside of the foundation too.

Cement Block Retaining Walls

  • The Findlay-Evans Waterproofing Team inspect and prepare the surface substrate prior to the waterproofing application.
  • Our aim is to have a surface that is smooth, dry and free of any contaminants like grease, mould etc.
  • Preparation sometimes require primers/patch work to ensure the substrate is as monolithic as possible.
  • Often the wall-footing joints, require cement or other trowel-grade material to form a “fillet” (radius or cove) before applying the waterproofing system.
  • However we find inevitably small holes, cracks and defects do get missed.
  • It is very difficult to make sure 100% of all surface defects are covered.
  • And unfortunately these defects often only show up after the waterproof coating has been applied.

     
Rendered wall prior to waterproofing application.

Quality Waterproofing Application

  • To 100% prepare a surface to accept the waterproof membrane,F.E.W offer a premium process.
  • Our premium preparation is to completely bag/render the surface prior to waterproof application.
  • Complete bagging covers the entire wall with an acrylic coat providing a monolithic surface perfect for a waterproofing membrane.
  • The bag/render surface also provides even extra waterproof resilience.
  • All tie-holes are properly filled.
  • After the waterproofing coat is applied to the correct thickness, the membrane will last indefinitely – it will not dry out, crack or peel off the wall.

Balcony & Instant Grass

Posted on by Waterproofing Melbourne

Synthetic turf can transform balconies, roofs and apartment terraces into a beautiful, green lawn all year round

Instant Grass will give an immediate WOW finish for your balcony or rooftop terrace.

However if you are installing artificial lawn on roofs, rooftops or balconies, it is critical to have an effective waterproofing membrane underneath these systems.

  • Instant grass will not perform as a waterproofing membrane itself.
  • The balcony or rooftop has to function as a structure first and foremost – and that means keeping the building watertight using a membrane in combination with instant turf.
  • Water can penetrate through the latex backing of instant grass and will track its way, and often over quite a distance, to rooms and structures below.
  • We have developed a unique and specialized waterproofing membrane system that is ideal for instant grass installations for all balconies, apartment gardens, roofs and rooftop terraces .

Findlay-Evans Waterproofing can provide waterproofing membrane systems that also include instant/synthetic grass installation as a finished project.

Give a Tired Balcony a Make Over

  • Rooftop terraces and balconies need to be completely water tight and kept permanently sealed to provide long term protection against moisture penetration and the disastrous consequences of water leaks.
  • F.E.W Waterproofing can install a protection barrier system directly over timber decking or hard substrates like tiles, concrete, masonry, brick or steel.
  • We use a LIQUID APPLIED membrane system that combines meticulous preparation, use dedicated protection barrier sheets that are ideally suited for spray application of these high performance flexible waterproofing membranes.
  • Our elastomeric coatings demonstrate extreme adhesion to nearly all substrates – guaranteeing a fully bonded membrane system.
  • No lifting, peeling or splitting with seams or laps.
  • Liquid rubber membranes also have the amazing ability of flexibility – providing expansion and contraction – a necessity for roofs and balconies.
  • A flexible membrane will not crack over time due to structure and/or substrate movement.

  • If balconies are not waterproofed correctly the first time, you may be faced with repairing your balcony surface over and over again if the CORRECT repair system is not used.
  • Accumulation of calcium crystals and salts that disfigures the top edges or underside of balconies are known as “Efflorescence“.
  • Efflorescence cannot form in the absence of water.
  • The waterproofing product chosen for balcony restoration should have the correct amount of expansion capabilities as the surrounding structure.
  • Must be able to adhere to them and create a bond and seal.

     

Tips to Waterproofing & Seal Balconies

The following tactics will help to ensure good balcony sealing and avoid water ingression.

  • Complete all penetrating works PRIOR to applying the waterproofing.
  • Choose a sealant or membrane material that suits your balcony structure, balustrade materials and roof materials.
  • Ensure any penetrating material are applied with an additional sealant that will create an additional seal on these.
  • Make sure you have a good drainage plan worked out with the balcony levels so not water pools are created.

Waterproofing Under Concrete Slab

Below ground waterproofing is as important as your foundations supporting the entire structure.

  • Without the combination of sound footings and waterproof structures a building will deteriorate rapidly.
  • Below grade systems are often inaccessible for repairs and extremely costly if modifications or rectifications are necessary at a future date.
  • Positive-side waterproofing systems are post-applied to the surface of the substrate directly exposed to moisture, typically the exterior side of the foundation wall.

  • The traditional plastic barrier used for under slab protection is a moisture barrier and is NOT a waterproof membrane.
  • Liquid Applied Membranes are particularly suitable for gas vapour barriers for mitigating methane & VOC intrusion.
  • Waterproofing Membranes installed under concrete slabs must provide permanent vapour, gas, chemical & water protection.
  • Liquid Applied Waterproofing provides a seamless and flexible membrane that will also move with the concrete foundations.
  • This means there are no JOINS or SEAMS – which are often areas of potential weakness due to possibility of tears during construction & over time.

Enduring Solutions for Balcony Leaks: The Right Products, Systems and Expertise for Durable Waterproofing

Repairs to leaking balconies require expert & correct waterproofing products & method to permanently stop water leaks.

Providing a membrane system that “works & lasts” is not difficult, however our Team has come across so many balconies that should not leak in the first place and then the repairs also fail to provide a solution to the problem.

As Registered Building Practitioners AND Certified Waterproofers, the Findlay-Evans Team always check leaking balconies with respect to balcony design & structure as well as the waterproofing system.

Very often leaking balconies are a combination of the above:

  • Failed waterproof product & system
  • Lack of, or insufficient number of, expansion joints
  • Inadequate and/or no drainage
  • Minimal or no falls built into the balcony design

A recent insurance survey has shown that “Balcony Waterproofing” has the highest failure rate of all areas in the building envelope.

However only 1.8% of the total construction cost is spent on waterproofing membranes for balcony areas, and yet leaking balconies account for a staggering 83% of building defect complaints.

     

Balcony Waterproofing Systems

  • Balcony areas are exposed to full climatic conditions and if installed incorrectly or inferior products are used, the chance of failure is high.
  • Repairs & modifications to a balcony membrane & surface provides an essential and integral part of the building envelope and should not be taken light-heartedly.
  • Waterproofing balcony surfaces, especially balconies with rooms below and rooftop terraces should be a well thought out process and not reliant on cost alone.
  • Ideally membranes are installed correctly from the outset and with quality products – as failure of balcony waterproofing can result in catastrophic water damage to structures below and even complete collapse.

Experts suspect poor waterproofing in Berkeley balcony collapse. Sudden collapse of a Berkeley balcony last week that killed six and injured seven, experts say it’s obvious what happened: water got into the balcony and didn’t get out, rotting the wood that kept it in place. Read about this tragedy here.

The results of poor workmanship was sadly demonstrated in 2014 in the USA when an apartment balcony collapse with loss of lives and major injuries. The Berkeley balcony that failed was only 8 years old.

Construction crews remove pieces of a balcony that collapsed in Berkeley, exposing what appears to be dry rot lumber. The collapse killed six people and injured seven a few blocks from UC Berkeley. (Mark Boster, Los Angeles Times)

Tiling on its own is not an effective or acceptable as a waterproof barrier.

Despite the severity of the potential consequences of balcony failure, many property owners do not use qualified & certified waterproofers; often allowing tilers to apply the waterproofing membrane & also use sub standard products.

Waterproofing Details for Balconies

  • Balcony membranes require a membrane system that provides a permanent water barrier to all wall upturns, floor, around drains, balustrade & all points of penetration etc.
  • Water has to be prevented from penetrating beneath the balcony surface, where structural damage will compound over time and is often invisible.
  • Water can track great distances from the point of entry.
  • A basic principle in construction is to factor in building movement – the normal cyclic expansion & contraction of materials.
  • The waterproof membrane has to flex and move with not only the balcony structure but also the associated adjacent building envelope.

Designing, Building & Waterproofing Balconies

To assist the public & building practitioners, the VBA has developed a list of important points to remember when designing, assessing, approving waterproofing standards for balconies.

Repairing a Leaking Balcony

Waterproof membrane best for remedial & repairs works


Extreme Flexibility: Flexible Waterproofing Membrane

Liquid Applied Membranes

Seamless liquid applied elastomeric membranes have become the ultimate solution for balcony, deck and above ground waterproofing.These extremely flexible membranes are capable of resisting UV rays – important if under timber decking – and also coping with structural movement and deformation. Liquid Applied Membranes are a cost effective solution to waterproof a new balcony and/or repairs to existing balconies.

Case Study- Video Below

Liquid Applied Membranes

  • Cost effective, robust & long life waterproofing.
  • Capable of bridging cracks and joints.
  • Fast installation with minimal disruption to building occupants.

Liquid Applied Waterproofing Systems are the ideal membrane to use as a sealant around the most complex of balcony details – for example around handrail supports, joins & seams, roof penetrations, rainwater outlets.

Waterproofing Membrane under Timber Decks

Seamless liquid applied membranes have become the ultimate solution for deck waterproofing. A quality balcony waterproofing  membrane is especially essential for preserving any area underneath timber decking from water causing ingression damage to rooms below.

Balcony Waterproofing – Australian Standards

Recent article in Melbourne’s The Age 25 September 2016:

“Melbourne’s high-rise nightmares taking a tall toll on residents and investors”

Access Full Article Here

Summary of the Article key points:

  • Residential multi-story, multi-dwelling, apartment buildings are experiencing an alarming frequency of building defects, most commonly caused through waterproofing failure.
  • Developers were identified as partly responsible for the condition of the building, with a call to be financially responsible.
  • Balconies were identified as a major cause of waterproofing problems, with the assumption that “proper waterproofing membranes have not been installed”.
  • Faulty windows and installation process causes considerable water leaks into walls and ceilings. Pressure issues identified as causes were nominated as; a failure to pick up defects through the building surveyors inspection process; plus the cost pressures to use cheap (inferior) materials to save money.
  • The market has inconsistencies in Insurance cover, both from building trade cover and the residential owners cover. Resulting in the building owner necessitating to self-fund the corrections to the building.
  • The Victorian Government is making new laws to protect consumers whilst also recognising the ‘overwhelming majority of builders’ do the right thing.
  • We recommend liquid applied membrane systems for the Australian climate as the most practical and economic products for a secure job.
  • A basic principle with new construction buildings is to view the job with the perspective that building movement will occur and therefore to secure all wall/floor joints, drains, balustrade, water exit points, hobs, sheet joints and movement joints.

Balcony Waterproofing Without Removing Tiles

Opinion piece by Paul Evans – President, Australian Institute of Waterproofing (AIW) 2017-2020

  • Re-Grouting and sealing is definitely not the way to repair a leaking balcony that has an existing defective membrane.
  • Sealing the existing tiles would probably stop or slow down leaks for a while until it moves and cracks the grout again then it would start to leak.
  • Laying a new waterproof membrane over a clean existing surface can work if the existing tiles are soundly fixed.
  • There may be some blistering with the new membrane due to water vapour trapped within but that is easily dealt with – balcony repairs just take longer while you wait for the vapour to dissipate ( with the new membrane over the top).
  • When repairing balconies it is alway better to have the A/C units etc removed while restoration works are done – a much tidier job.

Membrane Protection for Balconies

Instant turf is a popular finish for many balconies & rooftop terraces. However Instant Turf is NOT a waterproof membrane itself – we have a high performance waterproofing system which also includes a premium protection between the membrane & instant turf.

     

Our Team provide a tough, robust and durable external laminate protection sheet using our premium system: ARMA-BLUE

  • This composite product uses cross linked foam and has many benefits over conventional CoreFlute Board.
  • This is a self adhesive or “sticky back” impact resistant foam sheet that is laid down and then the instant grass is installed over the ARMA-BLUE.
  • Arma Blue protection sheet assists with allowing water run off.
  • Many balcony designs have limited fall and unless the waterproof membrane can “hold” water they will break down over time.
  • Liquid Rubber Membrane which is designed to “ponding water”, unlike a great deal of other membranes.

Rooftop & Balcony Waterproofing Methods

Liquid Coating Systems will bond to a great many substrates, allowing its use in many situations without having to remove and dispose of the existing surface.

  • This saves time and avoids the cost of removal and cost/environmental issues associated with disposal.
  • Remedial Waterproofing present many challenges and Liquid Membranes are suitable for many repair projects.
  • Liquid System makes it easy to seal and make water tight around all existing fixed structures and utilities.

Video Case Study – Waterproof Repairs to Concrete Roof

Video below outlines waterproofing repairs to an industrial roof & plant deck area.

  • The severely deteriorated existing roof membrane was leaking into rooms below.
  • It was not a viable option to remove the original roof membrane so spray-apply liquid membrane was the ideal repair product.
  • The new waterproof membrane, Liquid Rubber, was spray installed over the existing surface in a matter of days.

Roof Waterproof Coatings

Liquid Membranes offer a long term solution for exiting roofs & can often be applied directly over existing & damaged surfaces – saving time & money.

  • The rooftop project in images below had existing roof membrane that was severely damaged and causing extensive water damage to structures below.
  • Existing roofs often have difficult access so removal and replacement can be prohibitively expensive.
  • The existing leaking roof membrane was prepared and then over-sprayed with a Liquid Rubber Waterproofing System.
  • This spray applied waterproofing method provided a seamless, monolithic membrane that coated around all upturns, stairs and rooftop deck and plant equipment.

Heat Reflective Roof Coatings

  • This roof repair project was completed with white Thermal Reflective Top Coat over the base coat of Liquid Rubber.
  • Heat Reflective Coatings provide a robust and flexible roof membrane that also reduces interior temperature up to approx 8 degrees.
  • As a cool roof coating, heat reflective products are an excellent top coat to spray over the base coat membrane – this 2-stage system provides a protective long life solution for roof leaks.

Thermo Top Coat is not just a roof paint but a waterproof membrane in its own right.

Waterproof Repairs to Leaking Roofs

Very often when choosing to use Spray-Applied Waterproofing Membranes, there is no need to remove the existing roof surface.

Spray application is extremely fast – saving costs and time involved with a complete roof replacement.

  • In fact with Roof Case Study above removing and replacing the damaged membrane was not an option.
  • The roof structure was part of a power station and consequently it was not feasible for the roof to be removed.
  • Added to this was the challenge of providing waterproof repairs in a timely manner.
  • So speed was an essential element for choosing rapid sray applied Liquid Membranes.
  • Added to this ware the challenges of bridging the transition between the new membrane and existing roof.
  • Spray application for the waterproofing membrane was the perfect solution.

We have looked at many different products and are really pleased to have developed a system that ticks all the boxes – LIQUID WATERPROOFING MEMBRANE combined with a HEAT REFLECTIVE TOP COAT.

How to Waterproof Concrete & Metal Roofs

Repairs to Roof Waterproofing Membranes

The consequences of a leaking roof are often extremely costly -and may involve extensive water damage to infrastructure below and sometimes to adjacent properties.


Leaking roof due to water pooling & tracking under sheet membrane.


Using Liquid Waterproofing Membranes

Roof Membranes Deteriorate Due to Various Reasons

  • Cracks may develop due to an inflexible membrane that cannot cope with the normal thermal movement of a roof surface.
  • Waterproof membrane is not UV Stable and deteriorates with age.
  • Roof membrane uses joins, seams or overlaps that de-laminate and allow water to migrate under the membrane and track along the roof surface.

Flat Concrete Roof with Severe Cracks in Existing Membrane

Case Study Video Below

Using Correct Roof Waterproofing Products

  • Conform to Roof Shape – ability to seal & waterproof around roof services & fixtures.
  • Critical for Roof Coatings – commercial & industrial roofs often have complex shapes & contours that require liquid coatings that can seal vertically and horizontally.


Careful preparation & masking of existing rooftop services.

Roof Waterproofing Systems

  • Membranes with seams and/or joins often become areas of weakness for future water leaks.
  • Waterproofing installation using heat and/ or fumes have the potential to damage infrastructure, wiring and creates OH&S issues.
  • Equipment & methods need to be suitable for confined spaces, elevated surfaces and portable for roof repairs.
  • Roof repair may require structural knowledge & construction experience.
  • Repairs methods, waterproof products used need to be appropriate for each project.
