A home in Nestleton Station, Ontario had full perimeter water seepage in spring thaw and when the snow melts. The customers wanted to renovate the basement in order to rent it out. The floor would be all wet from the leaking perimeter causing the basement to flood and restricting the use of half the home. 

The customer called Clarke Basement Systems to waterproof their home. Chris Luke explained precisely what would be done to fix the problem. Dave Jackson and his team came in and installed a WaterGuard® Below-Floor Drain around the perimeter of the basement. A ThermalDry® wall membrane was mounted on the walls to keep moisture away from the basement and direct any water seepage into the WaterGuard®. The WaterGuard® then pushed the water into the newly installed SuperSump® Premier Sump Pump to avoid flooding.  Lastly, an IceGuard® Discharge Line was established outside the home to protect the system from freezing and breaking.  The customer can now finish the basement and rent it out without having to worry about wet floors and basement flooding. The customer has a Full perimeter waterproofing system with 25 year warranty!

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Nestleton Station home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall. 

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques.

Job Stories From Nestleton Station, 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.
