A homeowner in Blackstock, Ontario, previously waterproofed from the outside of their home. They learned this other company's systems have no warranty against water entering under the basement floor. When this happens it is called hydrostatic pressure and many basements suffer from it. The customer contacted Clarke Basement Systems to fix this problem- and we include a warranty!

We installed a WaterGuard® Below-Floor Drain around the perimeter of the basement to keep out any water leakage. We also installed a SumpPump to keep flooding under control. Lastly, we installed a ThermalDry® Vapour Barrier to seal the basement walls and provide a radiant barrier for heat. Now this customer can relax knowing his newly waterproofed basement has a warranty for years to come!

Job Stories From Blackstock, ON
Block Wall Leaking in Blackstock, ON

Clarke Basement Systems provides a long-lasting solution to permanently waterproof your basement. Our customer in Blackstock, Ontario, contacted us regarding a block wall that leaked at the floor-wall joint during heavy rainstorms and spring thaw. They were unable to finish their basement because of the leak and the water seepage was causing damage to the finished basement.


Chris Luke, System Design Specialist, met with the homeowners and provided a waterproofing solution. Lucio, a Foreman, and his trusted crew went ahead and installed:

  • ThermalDry® Wall Membrane
  • WaterGuard® Drainage System

These systems work together to eliminate water seepage. ThermalDry® directs water into the interior drainage system. The WaterGuard® collects water from the floor-wall joint and directs it into the sump.


The basement is now dry and our customer is relieved to have their basement protected! They can finally start finishing their basement without worrying about water damage in the future.
