Residential Photo Album: Sunken Slabs Cause Pooling Water, Aurora, ON

A home in Aurora, Ontario, had sinking concrete located at the back patio and side walkway. They had sunk about 2.5” and both areas were sloping towards the foundation. After heavy rains, water would flow towards the foundation and would pool in both sunken areas. The customer was concerned that if water kept flowing towards the foundation it would eventually make its way into the basement which would cause an even bigger problem. The customer called Clarke Basement Systems and spoke with John DiNicolantonio, the Project Lead, to get all the information about the project and all questions answered.  Billy McKeown and the Canadian Concrete Leveling team came in and used the PolyLevel Foam System and NexusPro Joint Sealant. They were able to use the PolyLevel Foam System to lift and level both the back patio and side walkway. The NexusPro Joint sealant was applied between the slabs and the home to further protect the foundation from water penetration. They drilled small dime sized holes through the concrete and injected our PolyLevel Foam underneath the slabs. The foam followed the path of least resistance underneath the concrete to fill all of the voids and then expanded. We were able to use the expansion of the foam to lift the patio and walkway to protect them from further settlement. The customer is satisfied that water is no longer flowing towards his home and that we have given them a much more usable outdoor space.
