Foundation
Problems
 |
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 stickGaps 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

outside your house for:
- Cracks
in the masonry
- Gaps
between bricks, doors and windows
- Bricks
leaning away from garage doors
- Gaps
between fireplace and house
- Sagging

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,
which is referred to as upheaval. |
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 conditions
