Bowing, Buckling or Leaning Foundation Walls
How To Repair A Foundation Wall Failure
Your foundation walls are bowing, buckling, or leaning inward.
This Could Include:
Stair-step or horizontal cracks along the foundation walls
Diagonal cracks at corners of poured concrete foundation walls
Bowing or bulging of the foundation wall inward.
Foundation wall sliding inwards on the bottom of the wall
Basement wall leaning in at the top – no longer plumb.
Signs of bowing foundation walls
Foundation walls move inward primarily due to expansive soils and hydrostatic pressure on the walls from outside. However, foundation walls may also crack due to many other outside causes, including foundation settlement. Our foundation experts will accurately identify the cause of your home's foundation problems.
Below are images of several foundations that are showing damage from hydrostatic pressure and expansive soils outside the structure.
What Causes Cracked & Bowing Foundation Walls?
The soils around your home can put enormous pressure on foundation walls. The amount of pressure they exert depends on four factors:
The type of soil around the foundation
The amount of moisture in the soil
How far underground the foundation is
The temperature conditions
There is a constant pressure on your basement or foundation walls from the outside. Hydrostatic pressure, expansive clay soil, and frost can all exert enough pressure to cause walls to lean or even collapse.
Gutters and downspouts can also contribute significantly to foundation problems.
If roof runoff is not directed away from your foundation, the soil around the foundation will become heavier and more expansive as it's saturated with water.
How Much Does Moisture Affect Clay Soils?
These two clay samples started out exactly the same in size, weight, and composition. The sample on the right was allowed to dry out, while the one on the left we kept moist.
If a small sample of clay can gain this much volume when it gets wet, just imagine how dramatic the changes are in the soil around your home!
