    Retaining Wall Stabilization, Mississauga, ON

    A homeowner in Mississauga, Ontario, had a retaining wall in the back of their yard that was starting to bow in a way that was potentially dangerous. They were worried that if it were to fall over it would be very expensive to replace. The customer knew they needed a quick and reliable solution. They called Clarke Basement Systems to find a solution for their foundation issues. Our Foundation Supportworks Team came in to stabilize this retaining wall permanently. We installed Geo-Lock™ Wall Anchors, extending from the ravine at the back of the property through the retaining wall into the yard. Now, the retaining wall is stable, and the homeowner now has the peace of mind going forward that their retaining wall will never move again.

    Foundation Settling Causing Damage to Whole Home in Toronto, ON

    A home in Toronto, Ontario had a problem in the basement along the back wall and corner of the home. If the foundation was settling and it would cause damage to the upper floors of the house and could become structurally unstable. The homeowner noticed a step cracking in the block foundation wall which was the result of the foundation settling. The foundation could become unstable which would damage the upper floor finishing and also could adversely affect the value of the home should they decided to sell. The customer called Foundation Supportworks to come in and fix the problem. Ron Monk explained everything that would be done to fix the home. Shane O’Rourke and his team came in and used Push Pier Vertical Assembly. The Foundation Supportworks push pier assembly installation is complete with a heavy bracket connected at the bottom of the foundation. The pier pushes into the ground until the equipment measure that it has hit solid bedrock. At that time the weight of the home is transferred to the pier and off the failing soils.

    Cracked Concrete Deck Repair in Oshawa, ON

    A customer had issues with a settled and cracked concrete pool deck. After contacting our company, our team injected our PolyLevel® underneath the slab. They began by drilling small dime-sized holes through the concrete slab and inserting the polyurethane foam. It follows the path of least resistance, pushes down loose soil underneath, fills the voids and makes the concrete level again. This process helps to protect the entire area against any future settlement.
