Seal Concrete Roof – Melbourne

Liquid Applied Membranes are the ideal roof coating for complete roof restorations or roof leak repairs.

Flat or low-slope commercial roofing systems may have areas where “water ponds“- ponding is unwanted pooling of water which accelerates the deterioration of roofing membranes, rooftop equipment & supports.

Failed Existing Roof Membrane

Ponding water allows the movement of solvents in existing older style of roofing systems to leach out and evaporate, leaving the roof membrane brittle and susceptible to cracking and leaking.

Commercial Roof Waterproofing Methods

• Waterproofing repair methods for flat and low-sloped concrete roofs need to stop roof leaks in a timely manner, and waterproof not only the roof surface but also around ALL roof penetrations, roof drains & rooftop installations and equipment.
• Roof coatings must also make water tight vertical surfaces, flashings and parapet walls.
• Roof repair methods must be capable to make water tight over many different existing and failed roofing systems: asphalt, gravel and tar, EPDM built-up (BUR), and modified bitumen.

Sealing & Waterproofing Commercial Concrete Roof

• Very often the condition of the existing roof surface is such that there are multiple leaks at various locations.
• This can lead to water ingress internally with damage to roof infrastructure and spaces below.
• Complete removal of commercial roofing systems may force a complete shutdown of rooftop services i.e heating and air conditioning- turning the waterproofing project into a construction site.
• Logistics, time and issues with shut down of rooftop services means that Liquid Applied Membranes are the ideal roof waterproofing system.
• Liquid Applied Membranes can be sprayed over the existing roof surface.
• Roof Waterproofing with Liquid Membranes – spray applied, fast, efficient & cost effective.

Roof Waterproofing Company Melbourne

• Findlay-Evans Waterproofing, a specialist waterproofing contractor based in Melbourne, has introduced an innovative technology to the services.
• The company is now using liquid-applied waterproofing technology, which means they can apply seamless and flexible membranes to both new and existing roof surfaces.
• Paul Evans, Registered Builder & Certified Waterproofer, provides Liquid Rubber roof waterproofing services to commercial & industrial sector, commented:

“Roof leaks are a serious problem that can cause irreversible damage if not handled in a timely manner.Unfortunately, many property owners put off the waterproofing process because they think it will be tedious and costly.The good news is that the liquid membrane technology that we use in our projects helps to solve both of those problems.Our spray-on membrane products provide a long-term waterproofing solution but also happen to be quick to apply and allow us to pass significant cost savings on to our clients.”

• Using Liquid Roof Waterproofing Membrane technology, the Findlay-Evans team can provide long-lasting waterproofing membranes for a number of roof types, surfaces, and conditions.
• Spray-on membranes are high-quality, and the fact that they can be sprayed over existing services makes them a more cost-effective alternative to roof or membrane removal and replacement.
• Findlay-Evans’ roof waterproofing products set instantly after application.
• This makes for roof coatings a rapid installation – up to 3 times faster than conventional roof sheet/torch-on systems.
