    Customer Testimonial

              The representatives at Canadian Concrete Leveling, including CJ, my sales representative, the contractors Kyle and Mark, were and are extremely professional to the core. Extremely knowledgeable in their fields, while answering all questions, concerns and possible issues in a professional manner.The request was to fill a void two to four inches below my enclosed porch slab, and to level the concrete slab around my pool. While they had to reschedule the first work date due to weather, they showed up on the reschedule date promptly, while calling in advance with their ETA.They worked relatively neat, cleaned up after themselves and completed the job in approximately three hours. The work exceeded my expectations. Well done Canadian Concrete Leveling.

    Sinking Pool Deck Puts a Stop to Family Fun in Whitby, Ontario

    Watching kids grow from infant to toddler is an exciting time for any parent. Children are starting to find their sense of curiosity during this age, and love to explore everywhere they can.

    For parents in Oshawa, Ontario, an unsafe pool deck forced them to bring a halt to their kid’s backyard adventures. A cracked and uneven pool deck was a huge tripping hazard for their little ones and was a sore spot when having company over. They take pride in their home and unfortunately, inherited the cracks when they purchased the house, not realizing it would be such an issue. 

    Tired of the embarrassment and looking to give some freedom back to their kids, they reached out to Canadian Concrete Leveling.

    Project Manager Kyle O’Brien met with the family at their home and inspected the pool deck. He recommended our PolyLevel® injection System to level the concrete slabs and our NexusPro® System to seal the cracks. 

    The customers booked a date for the repairs, and Foreman Kyle McKeown and Installation Specialist Mark Sealy completed the work. After a few minimally invasive injections to lift the concrete slabs and fill any voids, the tripping hazards were gone. The cracks were sealed, preventing moisture from getting beneath the concrete. Our sealant process also improves the aesthetic of the concrete significantly. 

    The customers are thrilled they can finally enjoy their pool without the hazards looming over them. Their sense of pride for their backyard has returned, and they’re happy to have friends and family over once again!

    Sinking Concrete Step in Uxbridge, Ontario

    Pouring and installing a concrete patio can be a costly endeavor and something that you don’t want to have to repeat. When cracks or settling happens, it can be hard to figure out the next step.

    A customer in Uxbridge, Ontario, had a beautiful backyard with a concrete slab patio. The concrete had settled, causing a large step to sink. Concerned about more future damage, the customer met with Project Manager Joe McColl. Joe inspected the step and backyard before a date was set for the repair.

    Foreman Kyle McKeown and Installation Specialist Mark Sealy used our PolyLevel® System to lift the concrete step back to its original position. After the lift, the drill holes were filled with concrete, giving the step a finished look. 

    The customer is very happy that his step is in the correct position once again, and his investment is protected.

    Garage Entrance Sinking in Uxbridge, Ontario

    A garage is an excellent addition to a home, but like everything, they require maintenance and upkeep.

    A customer in Uxbridge, Ontario, had a small garage connected to his backyard. A concrete patio led to the garage, but the slabs had settled over the years and created a tripping hazard.

    The customer wanted to remedy the situation and reached out to Canadian Concrete Leveling. Project Manager Joe McColl showed the homeowner our methods, and he was thrilled to see our solution.

    Foreman Kyle McKeown and Installation Specialist Mark Sealy drilled several dime-sized holes and injected our high-density polyurethane to lift and level the concrete. They pumped one hole at a time, giving the concrete an even, controlled lift.

    The customer is happy that his concrete is level. He can safely walk into his garage without the threat of a tripping hazard.

    Backyard Step Sinks in Uxbridge, Ontario

    Nature and the elements have a way of taking a toll on things. Wood, metal, and especially concrete, bear the brunt of everything Mother Nature throws at it.

    A customer in Uxbridge, Ontario, was dealing with an uneven concrete step in their backyard. Poor soils below had shifted over the years, and now there was a tripping hazard where there shouldn't be.

    The customer reached out to Canadian Concrete Leveling and met with Project Manager Joe McColl. Joe inspected the backyard and showed the customer our PolyLevel® System

    Foreman Kyle McKeown and Installation Specialist Mark Sealy drilled dime-sized holes through the top of the step and injected our high-density polyurethane to lift the concrete.

    The customer is very satisfied with the work done. He doesn't have to worry about tripping, and the soils beneath his step have been stabilized.

    Sinking Concrete Floor Threatens Ski Lift in The Blue Mountains, Ontario

    Properly working equipment can make or break a business, especially when it’s seasonal. Even losing one day due to a power or equipment failure can cost thousands and leave customers with a bad taste.

    A ski club owner in The Blue Mountains, Ontario, was concerned about losing the use of one of his lifts due to a concrete floor that had settled 2 inches. Beneath the floor was a conduit pipe that housed electrical cables and powered the ski lift, and the sinking floor was putting stress on the pipe. Not only could this cause a power outage, but it could also start a fire, shutting down the club and potentially hurting someone.

    Wanting to deal with the situation before it caused an emergency, the owner reached out to Canadian Concrete Leveling. Project Manager Joe McColl travelled to the ski club to meet with the customer for a free inspection. After checking out the building, it was clear to Joe that our PolyLevel® System could lift the concrete floor and remove the stress on the pipe. 

    Foreman Bill McKeown and Installation Specialist Mark Sealy started by drilling dime-sized holes in the concrete, being careful not to hit the pipe. They injected our PolyLevel® Polymer beneath the floor, lifting and leveling it to the base of the wall. Any voids beneath the floor were also filled, stabilizing the concrete to prevent any future sinking.

    The ski club owner is very pleased that there is no longer a risk of power failure or fire. His customers can rest assured knowing their day on the slopes won’t be impacted, and the customer is looking forward to a great winter in The Blue Mountains!

    Back Patio Settled and Cracked in Cumberland Beach, Ontario

    A customer in Cumberland Beach, Ontario, was concerned about their backyard. As custom home builders, they take extreme pride in the workmanship and the look of their home. Unfortunately, their beautiful flagstone patio had gone from backyard oasis to cracked and sloped water collector. The flagstone was built on top of concrete pads, which sunk when the substrate beneath them settled. This caused water to drain towards the foundation instead of away from it, making the patio unsightly and creating cracks and tripping hazards. The customer had also installed two unique, large armour stones that connected to the patio, which sank significantly due to the weight. Ready to bring their backyard back to life, they reached out to Canadian Concrete Leveling.

    Project Manager Paul Mendell met with the customer to review their options. After creating a plan, a date was set for Foreman Bill McKeown and Installation Specialist Mark Sealy to complete the work. They injected PolyLevel® in numerous locations, slowly raising and leveling the concrete. PolyLevel® not only raises the concrete, but it also compacts the ground below it, helping to prevent future settlement. To seal the cracks, Bill & Mark used our NexusPro® Sealant. NexusPro® is resistant to UV light and extreme temperatures, creating a seal that not only looks great but lasts long too!

    The homeowners are thrilled that they no longer have to worry about water draining towards their foundation and any tripping hazards. Their backyard looks great once again, and they can continue to take pride in their home and workmanship thanks to Canadian Concrete Leveling.
