Polyuerethane injection ensures that the crack has been completely filled, therefore, there is no void for water to creep into, freeze and expand once again.

 

While polyuerethane injection is almost always performed from the inside of your basement, we usually repair the outside of your foundation wall as well. This does require a little more work, however, it’s the only way to completely repair a foundation wall crack. We finish the outside repair with hydraulic cement and a waterproof skin.
