Exterior drainage systems are designed to stop water before it ever reaches your foundation. By excavating around the home, installing drain tile, and applying waterproof membranes, water is directed away from the foundation walls and into a safe discharge point.
This system is especially useful for homes with poor exterior grading, heavy rainfall, or frequent flooding. While more invasive than interior systems, exterior drainage provides a permanent line of defense against hydrostatic pressure and water intrusion.
Exterior drainage is a more extensive process, but it provides the strongest protection against water intrusion. Our team carefully excavates the soil around your foundation, installs a full drainage system, and applies modern waterproof membranes.
Once backfilled, the system ensures that rainwater and groundwater are directed away from your home – before it ever touches your basement walls.

Typically 3–7 days depending on the size of the home, soil type, and depth of excavation.
When properly installed, exterior drainage combined with waterproof membranes offers long-term protection.
No. In many cases, interior systems are sufficient. Exterior systems are ideal for homes with severe water intrusion or failing original waterproofing.
Yes. By directing water away from the foundation, exterior drainage reduces erosion that can weaken soil support and cause uneven settling.
Absolutely. In regions like Western Washington, where saturated soils are common, exterior systems provide an extra layer of defense against chronic leaks.
If you see pooling water outside, damp landscaping, or major seepage after storms, exterior drainage may be the right solution. Our inspections help determine the best fit.
