Mike has lived in his home for the last four years. Over time he has slowly noticed the sinking of the driveway and sidewalk. They did not want the problem to get any worse so they contacted MidAmerican Basement Systems. The PolyLevel technology that MidAmerica Basement Systems utilizes is a better alternative to mud jacking. The PolyLevel is pumped under the concrete slab and fills the void under the slab. The PolyFoam them lifts and levels the slab.
