Do you notice the basement walls bowing? Do you see horizontal and or vertical wall cracks? What causes basement wall failure?
The answer is Improper Drainage
Poor slope or drainage around a building causes surface water to drain away slowly, thereby increasing water infiltration next to the foundation. Increased soil moisture conditions increase hydrostatic (water) pressures on basement walls. If the combined hydrostatic pressure and pressure exerted by the surrounding soil on the wall exceed the wall’s design capacity, the wall will crack, bow, lean, or shear.
Clay soils are considered expansive when they have the capacity for extreme volume changes with fluctuations in water content. Expansive clays swell when wet and shrink when dry. Expansive, swelling clays against basement walls can exert lateral pressures on the walls of the magnitude of several tons per square foot.
Foundation wall cracks can worsen if they’re left untreated, especially in the case of cinder block wall foundations. Any crack or opening in the foundation can become a passageway for water to enter the home. Additionally, because the foundation wall is literally cracked through, the gap will continue to worsen as the walls move and become influenced by pressure from outside the walls. One crack in the foundation walls will lead to another and no crack will ever improve on its own. All cracks should be repaired if they’re allowing water through, and even a hairline crack can be evidence of a larger problem and should be inspected by a professional immediately.
Horizontal foundation wall cracks are potentially very serious problems that can sometimes lead to the complete failure of the foundation walls. These cracks occur when pressure builds against the side walls and forces them inward. Given time, this pressure can snap the walls, creating an enormous and devastating problem. If you detect any cracks, call Toledo Basement Repair for a free foundation repair estimate. Many options are available for foundation problems such as wall anchors and crawl space support beams that will competently repair your wall, contribute strength, and help prevent the inward movement of the walls, redistributing the weight to where the load can be better handled.
After most foundation stabilization projects, windows and doors that were stuck will once again work normally. Cracks in the walls will become repairable and furniture will sit level again.
Our foundation repair team uses engineering data and the latest technology to ensure that each foundation we repair is done right, on time, and cost-effectively – and stays that way. If your foundation is in trouble, please contact us for a consultation.
