A large horizontal crack running across your basement foundation wall is cause for concern. However, the crack doesn’t mean your foundation is doomed. Plate anchors can repair your wall.
Horizontal foundation cracks are signs of serious problems. The cracks are caused by hydrostatic pressure, which is water pressure pushing your foundation walls inward.
Water is a foundation’s biggest nemesis. Wet periods, which can be caused by rainfall, snowmelt, or a high water table, cause the ground to expand.
That expansion exerts pressure on your basement walls, forcing them inward.
If there isn’t proper draining around a home, some areas of soil may swell more than others also putting pressure on foundation walls.
Foundation walls made from concrete blocks or other masonry units are very good at handling compressive strength, which is the weight of a house above pushing down on the wall.
Where masonry walls struggle is with lateral loads. Lateral force runs parallel to the ground and perpendicular to the direction of gravitational pull. In other words, the pressure pushing inward on your basement wall is lateral force.
Exert enough lateral force on a foundation wall and the wall will crack, often at the masonry line.
Because foundation walls are load bearing, if the walls crack and lose structural integrity, the entire building can be compromised and in danger of collapse.
To protect your home and family, it is vital that you call the professionals at My Foundation Repairs immediately to inspect your home foundation cracks.
Horizontal foundation cracks are serious problems, but plate anchors from Earth Contact Products will correct the problem.
In a plate anchor wall system, holes are dug in the soil away from the foundation wall. Rods are driven through small holes in the basement wall and connected to exterior anchors installed deep in the soil.
On the interior of the foundation wall, a wall plate is placed and then secured to the rod.
A wall plate is placed on the interior of the foundation wall and then secured to the rod.
Using torque, the wall is then pulled back into place and stabilized.
