Cracks in concrete basement walls – both poured walls and block walls – can mean different things. Cracks in basement walls can be categorized into two groups: a) Short, Horizontal and Vertical cracks 1/16” or less in width; and b) Diagonal and Horizontal cracks greater than 1/16” wide.
What causes a concrete wall to crack?
Smaller concrete wall cracks can be in result of the concrete drying too fast due to weather conditions when poured. It can also be as simple as the wall bearing too much weight. Another common cause is the changing weather conditions.
Foundation settlement can cause wider diagonal and horizontal cracks. This occurs when the home starts to sink within unstable soil and then settle. This causes cracks in walls, specifically near ceilings and door frames.
Do I Need to Fix This?
Yes, small untreated cracks can allow water and insects into your home…you don’t want that. Further, wider cracks indicate a more serious issue caused by foundation settlement and/or hydrostatic pressure. Substantial cracks indicate a potentially compromised foundation that can easily lead to additional foundation damage and severe problems like large drywall cracking and separation, doors and windows that don’t open or close, uneven and cracked floors, and more.
Narrow cracks can be treated and permanently repaired by our crack repair specialists before they worsen. We utilize various epoxy compounds designed for the specific sized crack in your wall to seal off the potential entry point. The epoxy will keep out water and insects, and restore the structural integrity of your wall.
The wider, diagonal cracks or horizontal cracks in the wall that are more serious can be stabilized and possibly reversed using the Grip-Tite Push Pier System or Grip-Tite Helical Pile System which will provide a strong, stable support system resting upon a strong soil stratum far below the problem area. The horizontal, shear-type cracks can be stabilized and sometimes corrected utilizing the Grip-Tite Wall Anchor System which provides an anchor that can withstand the lateral forces against the wall by anchoring far away from the affected area and creating a stable, soil wedge with a soil anchor engineered to overcome the forces against the wall. Have one of our certified technicians determine which type of cracks are present in your wall and they will make the proper recommendations that will resolve your problem.
