Apart from a BBQ, the word pit is rarely ever used in a positive context. There are a million and one other words you can use like a hole, divot, depression, ditch, etc. But when this customer contacted us complaining about a “pit” on their basement floor, we knew that it couldn’t be good. Initially, the homeowner met with System Design Specialist Chris Luke. He thoroughly and patiently explained how Clarke Basement Systems could offer assistance to fix their specific issue and fill in that pit. After the customer agreed to the proposed systems and techniques, our Installation Specialist team began their crafty work.

Firstly, Dave Jackson and his installation team of skilled specialists safely removed the old, inefficient sump pump and replaced it with our unique TripleSafe® sump pump. Not only was the old sump not efficiently operating, but it also did not have the proper backup systems in place. This means in the event of a power outage or emergency, the pump will cease to operate, and the basement could flood. This incoming water can cause damage to the furnace, electrical components, and other essential utility appliances. Secondly, and finally, the “pit” was filled in back to level. So, the customer killed two birds with one stone and is ecstatic they found a service like Clarke Basement Systems to protect them for years to come.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Sunderland 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. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

  • Uneven Patios

Job Stories From Sunderland, ON
The Deeper the Pit in Uxbridge, Ontario.

A customer in Uxbridge, Ontario, reached out to Clarke Basement Systems, describing to us a unique issue that they had. Not only was their basement sump pump not operating at one hundred percent, but the pump was placed a few feet into the ground, creating a massive hazard in the basement floor. The customer promptly wanted both issues fixed so they could go on with their lives without worry. Our installation team immediately began removing the old, inefficient sump pump and replacing it with our patented TripleSafe® sump pump. With a power backup and multiple fail-safes, the TripleSafe® sump pump is by far the best option for anyone who worries about pump failures and power outages. After replacing the old with the new, the team poured fresh concrete into the pit while still allowing service access to the internal components via the top. And due to the proximity to the furnace, the system installed needed to be sure that it would function at one hundred percent efficiency for years and years no matter what. After all, was said and done, the customer was delighted, knowing that not only their basement would be dry, but that the immense pit of despair is now closed up forever, safe and usable.

Project Location: Sunderland, ON
I have a bungalow in the Uxbridge/Sunderland, ON area and have noticed the worsening of some cracks in my unfinished basement floor, along with some minor heaving. There is a hollow sounding noise when walking on the floor in the areas with the worst of the cracking and heaving. The foundation walls appear to be unaffected. I would like to have someone come to perform an inspection and suggest possible solutions with a quote.
