FLAT ROOF REPAIR & WATERPROOFING
We are a Toronto-based company specialized in seamless, fast-curing, polyurea-based spray-on membrane applications which ensure complete durable waterproofing.
Our material can be applied at temperatures as low as -5°C.
APPLICATION BENEFITS
Time-Efficient
Spray-on applications are much faster than roll-on methods.
A seamless fast-curing waterproofing membrane ensures complete durable flat roof repair.
Temperature Application Range
Our specialized flat roof polyurea-based materials can be applied at a much greater temperature range, going as low as -5°C, which is an advantage in commercial roofing industry.
Easily Adaptable
Materials used allow for application thickness to be easily adjusted, as required.
Applications can also be designed to cure at any rate between 30 seconds and 4 hours - curing time will vary depending on the application method.
UV Protection
Light-colour surface helps reduce heat absorption.
A UV-protective layer is applied for more durability.
REPAIR METHODS
Crack Repair
Thanks to monolithic adhesion provided by our products,
flat roof repairs are done quickly and efficiently.
To repair a crack on any concrete surface, a clearly defined procedure is followed: cracks are prepped and then treated with specialized, industrial-strength adhesive, after which they are filled with polymer cement and a waterproofing primer.

Patching
Under traditional repair methods, patching concrete requires a minimum of two-inch demolition in the affected area.
The use of specialized, industrial-strength materials permits patches as thin as 5 mm on any surface, making flat roof repairs much more cost-effective and faster.
EPDM Membrane Repair
A five-layer coating is applied after the roof surface is flattened, to provide an optimal commercial roof repair.
After the entire surface is power washed and valleys are filled with a self-leveling material, a fire-rated protector board is installed. Heavy sheets are then placed to flatten the roof, and the joints between them are detailed.
To ensure durable results, a five-layer coating is applied: a specialized primer, a liquid waterproofing membrane, fleece material, and another layer of primer, followed by UV-resistant coating.
Roof Capping
When aluminum capping shifts, this creates gaps around
roof edges which leads to leakage.
We realign the capping, seal the gaps and coat the entire surface with paint for further protection.
