Liquid Applied Waterproofing for Concrete, Metal, Timber & Flat Surfaces
Liquid Applied Membranes have the unique properties of extreme flexibility combined with seamless and robust bonding – all ideal qualities for a long life waterproofing membrane.
Liquid Membranes have a high viscosity formulation designed for application on both vertical and horizontal substrates.
The preferred waterproofing product for the roof project below is a Liquid Applied Membrane System combined with Thermo White Roof Coating.

Properties of Liquid Rubber Membranes
- Seamless – so no joins or seams as areas of potential weakness.
- Flexible – membrane contracts & expands with roof surface.
- Conforms to Shape – around roof services, rails, stairs etc.
- OH&S Compliant & Eco-Friendly – no heat, fumes or torches.
- High Performance - Long Live & Robust Adherence.
- Encapsulation – preserving whatever is underneath & protection from weathering.
- Cost Effectiveness – liquid roofing provides a cost-effective method of making a new or existing roof waterproof.

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.
