Drainage Problems Around Foundations
IN THE GREATER SAN DIEGO AREA
Why Drainage Matters
Poor drainage is one of the most common causes of foundation damage in San Diego. When water is allowed to collect around a home's foundation, it can cause soil movement, settlement, cracking, moisture intrusion, retaining wall failure, and costly structural repairs. Understanding the warning signs of drainage problems can help homeowners address issues before significant damage occurs.
A foundation depends on stable soil for support. Excess water can:
Wash away supporting soils
Cause settlement
Increase hydrostatic pressure
Create foundation cracking
Lead to retaining wall movement
Cause crawl space moisture problems
