Why Moline Foundations Move
Many Moline homes are a century old, built on stone and block foundations close to the Mississippi. The river-bottom clay soils swell and shrink with moisture, the water table runs high near the river, and decades of freeze-thaw take their toll — so cracks, bowing, and settlement are common even in well-built homes. Identifying the real local cause is half of recommending the right repair.

Why foundations move here in the first place
Quad Cities foundations move for a fairly predictable set of reasons: expansive clay soils that swell when wet and shrink when dry, freeze-thaw cycles that work on every crack, and hydrostatic water pressure against the wall. Knowing which of these is driving your movement is what tells us whether a wall needs steel bracing, a crack needs sealing, or the real repair is outside in the drainage. We diagnose the cause before we price the cure.

What Quad Cities homeowners say
“Behncke built an egress window for our home. From the initial scheduling through the conclusion everything was precise and the craftsmanship was perfect. We would highly recommend Behncke for your every need.”
