Homeowner Marcus has lived in his home for a few years. Over time he slowly noticed that the driveway outside of his home was sinking along with the steps to the front door. MidAmerica Basement Systems proudly offers top of the line concrete repair services in the form of polyurethane foam. Small ports are inserted into the concrete slabs where the foam will be pumped under the concrete. The foam is injected under the slab and fills the void under the slab that is causing the sinking and cracking. The foam expands into the void and hardens causing the concrete slab to lift and level.
