Foundation Crack Repair in Des Moines, IA
Cracks are what bring most people to a foundation contractor. Their direction, width and whether they're growing say far more than their length.
Request a foundation inspectionShrinkage cracks
Thin vertical cracks in poured concrete walls usually come from the concrete drying after it was poured. They're common and often only need sealing if they leak.
Stair-step cracks
Cracks that follow the mortar joints of a block wall, often near corners, point to settling or wall pressure.
Horizontal cracks
A horizontal crack in a block wall usually means the wall is being pushed inward; see bowing wall repair.
Track it
Mark both ends of the crack with a pencil and the date. Check again after a season to see if it has grown.
Sealing
Polyurethane injection fills leaking poured-wall cracks from the inside and flexes slightly with seasonal movement.
Upstairs signs
Drywall cracks above doors, nail pops and gaps along the ceiling can reflect movement in the foundation below.
Freeze and thaw
Water that gets into a crack freezes in winter and widens it. Keeping water away from the wall slows that cycle.
When to call
Cracks wider than about a quarter inch, cracks with one side offset and cracks that keep growing deserve a professional look.
