Liquid Polyurethane
We use a specialised single component or accelerated liquid-applied polyurethane waterproofing system to create an impressive waterproof barrier for any surface.
As one of the most effective methods in waterproofing a basement, HYPERDESMO® is a single component, liquid applied, polyurethane-based waterproofing membrane that can be applied in 2 coats. Curing in reaction to the atmospheric humidity, the sealant forms a highly protective and extremely hydrophobic membrane with excellent properties.
Applying the liquid polyurethane to the walls and floor of your basement will create a watertight seal that will keep your basement dry. Our impressive sealant is designed with high weathering resistance, the ideal solution that offers full protection.
At Southern Cross Projects Roofing & Waterproofing, we deploy a quick application and installation process, leaving behind a seamless finish with a 25-year guarantee.
When you decide to go with Southern Cross Projects Roofing & Waterproofing, you will receive unrivalled quality every time.
