Polyurethane Waterproofing

Did you know waterproofing typically makes up between 3 – 5% of the total project spend but is responsible for more that 25% of problems post construction?

That is why all commercial projects require the complex knowledge and experience to provide the most suitable solution.

Polyspray adds significant value to the waterproofing industry with our tight relationships with major suppliers. Our market leading application methods protect contents underneath or within, as well as protecting structural integrity.

We have got what’s required to protect structures from moisture and harsh environments to sustain the integrity of the structure to both new and existing concrete.

Our concrete waterproofing services includes the application of seamless spray applied Polyurea or Polyurethane membranes for both internal and external requirements.

Effective waterproofing systems rely on exacting application. If not done correctly problems can occur with non adherence to the substrate leading to leakage and corrosion.


  • Seamless Application

(75% of leaks are caused by seams)
The polyurethane system is seamless which means no leaks when properly installed
Single ply roofing systems have seams that rely on the installer to properly seal the seams. If not properly sealed the seam sealant deteriorates over time. The chance of water penetrating into the building is greatly increased with seams.

  • Polyurethane is Chemical resistant

Polyurethane coatings provide resistance to inorganic bases, acids, alkaline materials and hydrocarbon solvents.
Most roofing systems cannot tolerate chemicals. Polyurethane Roofing Systems will resist corrosive chemical fallout that can be exhausted onto a roof’s surface from the production areas inside of the building or from a neighbouring building.

  • Damming Water Resistant

The polyurethane roofing system can actually withstand permanent standing water conditions with no leaks. Many other roofing systems cannot make this claim. polyurethane Roofing Systems can actually withstand permanent standing water conditions. Not many roofing systems can make this claim. The family of polyurethanes used on roofs are used as secondary containment ponds liners that must not leak.

  • Speed of application

The speed of application available with the Polyspray’s Linings system ensures that your roof problems are solved far quicker and with far less disruption than conventional roof repairs.

  • Eco-Friendly

Environmentally safe – no VOC’s
Reduce energy costs with lower roof temperatures.
No Waste

*Applicable to several different roof substrates.
