To relieve pressure placed on your foundation walls from outside moisture and soils we begin the wall straightening process by excavating the soils out from around the foundation.
Leaning foundation wall.
In this case we d expect to not see horizontal cracks if the wall is masonry block for example.
Bowing leaning or rotating basement walls are a problem for many homeowners.
Bulged foundation repair methods where we describe the use of pilasters reinforcing steel i beams foundation anchors sister walls steel cables and even complete foundation wall reconstruction to deal with foundation wall bulging cracks leaning or movement.
Wall anchors can be a long lasting solution to strengthen retaining walls and actually pull them back as close to their original position as possible.
Horizontal foundation movement creep.
If your foundation walls have begun to bulge or lean inward it may lead to other structural issues in the basement and throughout the rest of the home.
Foundation walls normally start leaning due to lateral forces from hydrostatic pressure.
If the movement is minimal carbon fiber straps or steel wall braces are an appropriate repair to prevent further movement and the possibility of having to excavate and straighten the wall later.
Wall anchors can be used to shore up bowed or leaning basement walls but the same solution can be used in your retaining walls.
These issues are normally caused by a foundation problem.
Exterior excavation is only necessary when the foundation walls need to be straightened right away such as when the walls are dangerously damaged or you have.
The three most common causes are wet clay soil soil expanding due to moisture or frost heaving when cold temperatures cause soil to contract.
