Waterproofing Cracks in the Foundation
Where the water leaking into your basement through the foundation walls is relatively limited and isolated to a very specific area, it is likely that the water is coming in through a crack or rod hole. Even in cases where your construction was completed according to the Ontario Building Code, there may be leaking if the OBC-required coating has dried out allowing water penetration.
Wall cracks can occur in both poured concrete and concrete block foundations as the building settles after construction and as it is affected by the varying movement of the surrounding ground. In fact cracks are frequently part of the curing process for poured concrete. In addition, if your foundation is poured concrete, your builder may have missed or improperly sealed a tie rod hole that was part of the forming of the concrete. Regardless of the cause, remediation is required to make your basement dry.
At Benchmark, cracks are treated with the most advanced waterproofing technologies as described in our Waterproofing from the Outside article. It is worthy of emphasis to note that benchmark insists on a flexible rubber membrane and dimple board to accommodate movement and eliminated the problem of membrane desiccation. Our attention to waterproofing practices ends wall crack leakage.
