Foundation Settling,
Slab Settling and Repairs
Each year
sinking foundations, cracked and buckled walls, and cracked and uneven
floors affect millions of families. Buildings situated on unstable soils
will settle when the foundation is subjected to moisture or poor drainage. A
shifting foundation could result in structural damage and potentially, a
loss of your investment.
Look
inside your house for:
-
Cracks in drywall on walls and ceiling
-
Doors that stick Gaps between walls and ceilings
-
Nails that are coming out of the drywall
-
Windows that are not square or are sticking
-
Floors that are cracked or not level
-
Gaps between walls and floors
One of the most common causes of foundation movement is the
shrinking and swelling of expansive soils. The degree of soil movement is
determined by the amount of expansive material, and the variation of its
moisture content. During the spring, when the moisture content of expansive
soil increases, the soil swells. During the drier months when the moisture
decreases, the soil shrinks, allowing foundations to settle. During wet
periods, foundations return to their desired elevation. Sometimes, the soil
will swell enough to raise foundations higher than their desired elevation.
Causes
of foundation movement:
-
Poor site drainage compromising strength and elevation
-
Building on non-compacted fill causing structural
shifting
-
Plumbing leaks causing foundation and floor movement
-
Poor construction of the foundation based on the site
