Bay Area French Drain Installation & Emergency Flood Prevention
Much of the San Francisco Bay Area—from the flatlands of Menlo Park and East Palo Alto to the hillside runoffs of Woodside and San Carlos—features dense clay soils that trap heavy winter rain. When water has nowhere to go, it pools against foundations, swamps crawl spaces, and erodes landscaping.
Our team specializes in precision trenching, installing commercial-grade corrugated pipe & pump systems, and backfilling with clean drain rock. This multi-layered approach creates a reliable subsurface channel that safely diverts water away from your home's structural perimeter. Don't wait for the next major storm to test your yard's grading.
