Foundation problems in our area come down to one thing more than any other: uneven soil moisture. The clay swells when it is wet and shrinks when it is dry, and when one part of the house stays damp while another dries out, the foundation moves. The good news is that consistent, simple maintenance keeps that from happening.
-
Keep moisture even
Uneven moisture is the root of most movement. Soil swells where it is wet and shrinks where it is dry. Use a sprinkler system or soaker hoses to keep an even amount of moisture all around the home, and avoid overwatering a repaired section.
-
Drain water away
Water should always drain away from the house and foundation. Keep the grade sloping away, and make sure downspouts carry roof water at least three to four feet from the foundation.
-
Fix leaks promptly
A plumbing leak or bad drainage will swell the soil and shift the foundation. Address any plumbing or drainage problem as soon as you find it.
-
Mind the landscaping
Keep shrubs at least two feet from the foundation edge and trees at least ten feet away, with branches trimmed so the drip line does not reach over the house.
-
Let new soil settle
After a repair we leave dirt mounded over the pier areas. It settles with each rain or watering, so keep it graded to drain and top it off as needed.
-
Ask before you change the grade
Consult a professional before adding on to the home or changing the landscaping or grade of the lot, so a small change does not create a new moisture problem.
