Causes of Foundation Failure

allweb Uncategorized 0 Comments

There are many causes of foundation failure, here are some.

Soil Type

The most common kind of expansive clay can absorb so much water that it can swell by several hundred percent. Poor soil, organic components, debris, etc., may cause expansion or consolidation, which contribute to foundation failures.

Water problems

Too much rain, inadequate drainage or plumbing leaks can all cause foundation problems. Wet soil expands, pushing against your home’s foundation and over time can cause a variety of problems like bowed walls or foundation cracks.

Plumbing Leaks

Leaky plumbing results in moisture build-up that is often a major contributor to foundation problems. The degree of movement depends on the soil type, soil density, soil moisture content prior to the leak and the length of time over which the leak has occurred.

Poor Foundation Construction

Many general contractors are not foundation experts. Cut and fill situations, where soil is removed from part of the lot and stacked on another, must have proper soil stabilization before the structure is constructed. Otherwise, unexpected movements of the soil beneath the foundation may occur.
