In this Claremont, ON home one problem we faced was due to the water tank being so close to the foundation wall that we could not extend our WaterGuard®  Below-Floor Drainage System. A perfect solution for this situation was to install our TrenchDrain™ Grated Basement Drain to collect water and direct it into the interior drainage system.

Before, this basement had water leaking through the floor-wall joints. Then, we installed our CleanSpace® Vapor Barrier over the foundation wall to completely cover and protect against water seepage. It directs water into the interior drainage and sump system.

Only one wall stood in the way of finishing this basement. This one wall, in particular, was the root of all the leaking issues. Rather than having to waterproof the whole basement, only one wall needed the help of our systems to stay dry. The result was a fast repair, and a dry basement!

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Claremont 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 Claremont, ON
Basement Waterproofing in Claremont, ON

Clarke Basement Systems offers long-lasting waterproofing solutions for every situation. Our customer in Claremont, Ontario, had a stone rubble foundation that was leaking through the floor-wall joints. During the spring thaw, it became significantly worse making it a nuisance to go downstairs due to the wet floor.


After surveying the area System Design Specialist, Chris Luke, proposed a long-lasting waterproofing solution. Our Foreman David and his crew installed:

  • WaterGuard® Drainage System collects water from the floor-wall joints
  • TrenchDrain™ Grated Basement Drain
  • CleanSpace™ Vapor Barrier directs water into the interior drainage system


Our customer was relieved to have a fully waterproofed basement that will be protected for years to come. And with our transferable warranty, new homeowners will be covered. 

Work Requests From Claremont, ON
Project Location: Claremont, ON
Hi there; we're interested in finding out if our pool deck can be repaired/releveled. Pool is approx 25 yrs old and roughly half of the slab sections have pulled away from the coping.
Project Location: Claremont, ON
Need a back up Sump Pump
Project Location: Claremont, ON
Interest in pricing for a primary and battery back up sump pump in case of power failure. High water table which requires the sump to work fairly regularly.
