Residential Photo Album: Two Sunken Walkways Cause Many Hazards, Newmarket, ON

A home in Newmarket, Ontario had a front and side walkway that had sunk over the years. The front walkway had sunk 3 inches from the original pour and was causing a trip hazard as the step up to the front porch was now 11 inches. The walkway and shed along the side of the house had also sunk 2.5 inches which was causing a similar issue with the step leading into the garage. The customer stated that water would pool on the front walkway as it was no longer sloping away from the patio. The side walkway was sloping away but the customer was concerned about the height of the step and the potential for further settlement. The step height was very high and posed a serious trip hazard. With water pooling on the walkway there was also a slip hazard in the winter when the water would freeze. The customer called Canadian Concrete Leveling and talked to John DiNicolantonio, our Project Lead to explain what would be done to fix the issues. Billy McKeown and Kyle McKeown, our Poly Foremen came in and 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 walkways and protect them from further settlement. The PolyLevel injection lifted and leveled both the front and side walkways. The steps are now much more manageable and water no longer pools on the front walkway. The customer is satisfied and feels safe to use the walkways and are also very happy that they will no longer need to patch up areas of concrete that have settled.
