Maryland's geography creates drainage challenges unique to the region. The Piedmont Plateau's dense clay soils absorb water slowly and release it even more slowly — maintaining elevated soil moisture and hydrostatic pressure against foundation walls for days after rainfall events. Properties in low-lying areas of Anne Arundel, Cecil, and eastern Baltimore counties face high water tables that push groundwater upward through crawl space floors. Older neighborhoods with inadequate lot grading direct surface runoff toward foundations rather than away from them.
The result is crawl spaces that see water intrusion not just during major storm events, but during ordinary Maryland rainfall — and in some cases, continuously during wet seasons.
OBW Crawl Space Drainage Solutions
OBW installs interior perimeter drainage systems that capture water at the point of entry and route it to a sump basin. This approach — proven across thousands of Maryland installations since 1953 — is effective regardless of whether water enters through wall cracks, the wall-floor joint, or upward through the floor. The drainage channel runs along the perimeter just inside the foundation wall, collecting water before it can spread. A sump pump evacuates collected water through a discharge line routed to daylight. Battery backup ensures the system operates during power outages — when Maryland storms are most active.
Permanent Drainage with a Lifetime Guarantee
OBW's crawl space drainage systems are covered by our Lifetime Transferable Guarantee. If the system ever fails to perform as designed, we return and correct it at no additional charge.
