Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Orangeville 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.

Project Location: Orangeville, ON
Hello, I am in the process of trying to find someone to repair my basement. Last Tuesday during the heavy rain storm in Orangeville water started coming into my basement though my gas fireplace. We have had several people come in to take a look (emergency contractor, insurance assessor and forensic engineer), via insurance company. I have been told that the plank laminate flooring has water damage, and their is likely some water under the floor. I need the leak repaired which I believe is entering under the ground via the fireplace vent on the side of the house. I will also need any repairs done in the basement to remove the water and possibly replace all or parts of the existing floor. I wanted to know if I could get a quote regarding the approximate cost of the job. If you need to send someone over to have a look that is no problem. Thank you.

Looking for a free estimate as when I came home this evening to see there was some water in my basement. Enough to leave a pool of water. I did some of my own investigating and I do see a crack in my foundation from inside my home. Look forward to seeing what can be done about this and the cost as to the fix. Thanks.
