Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Port Hope 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 Port Hope, ON
Basement Waterproofing Job in Port Hope, ON

Allan W. never thought that the reason he wouldn’t be able to enjoy his retirement would be because of his home in Port Hope, Ontario. After working hard all his life he just wanted to travel, but his leaking basement wouldn’t let him! Every time he left to go away somewhere, his basement flooded, ruining all his personal belongings. After a few times of this happening, he couldn’t travel anymore, as he worried his basement would flood when he was away. Allan knew the problem needed to be resolved, so he called Clarke Basement Systems.


Steve Matthews, System Design Specialist, went to Allan’s home to help solve the problem permanently. He noticed that the water was coming in from the old concrete floor and left the basement smelling musty. Steve put together a solution to Allan’s problem that would guarantee water would never come in again! Jose Martinez, the lead foreman on the job started by installing a CleanSpace® Vapor Barrier System to not only catch water but contain the musty odor. Once the water is in the CleanSpace®, it is then funneled down to a full perimeter WaterGuard® system which drains all the water to our patented TripleSafe™ Sump Pump System. The water is pumped out and away from the house, leaving the basement COMPLETELY dry!


It is safe to say that Allan can now enjoy his retirement and continue to travel without worrying about his home.

I took possession of my new home on October 24th. After the first rain on Sunday, a lot of water came into the basement. I had an inspection done before I bought the property. The report suggested that there may be seasonal dampness, but this goes well beyond what I expected. The basement was very very dry at the time of inspection. There is a sump pump in the basement, but the water didn't reach to that area. Thank you, Maureen.

Hi there, I need to get some help repairing a minor leak from my patio into my basement. I don't think it's a big job and it is definitely time sensitive. Any help you can give me would be great. This would probably take two days max with one or two guys. I really appreciate you getting back to me. Thank you. Brent
