At StayDry, when we evaluate wall foundations, we generally find three different types of foundation movement that lead to wall damage. Foundations can settle horizontally, vertically, or a combination of these two different types of movements.
Vertical Movement In Foundations
Vertical movement in foundations is caused by downwards movement of the wall and wall footings. There are a couple of situations that cause vertical movement in foundations:
- A foundation that is situated above soft soil.
- Expansion of foundation walls due to freezing in cold climates.
- Clay soils, that tend to expand or contract with moisture and evaporation.
Horizontal Movement In Foundations
Horizontal movement in foundations generally is associated with building construction issues. Based upon construction materials used in the foundation and the strength of the wall, forces in the soil may cause bulges or bends in your foundation. Here are some of the common issues that we see:
- Bulging Wall Movement | Foundation walls will often bulge inward due to stresses placed upon them.
- Leaning Wall Movement | The entire wall may lean inwards rather than just one section.
- Shifting or Creeping Wall Movement | The wall may move inwards while remaining vertically aligned.
