The lifting process is a simple one! Take a closer look to see how everything works:

We use a long drill to make a hole no bigger than a dime. This is where we will insert the foam gun and begin to pump the polyurethane material.

With the gun inserted into the designated hole we can start pumping the polyurethane in increments. The foam takes 15-20 seconds to expand fully so it’s important that we pump in increments to ensure there is no over lifting.

As the foam expands, it pushes against the soil causing the concrete to lift. With polyurethane foam, you will be able to have full use of the concrete in less than a day!
