Portland's clay soils and winter rains create chronic drainage issues, especially in older neighborhoods like Ladd's Addition where original systems are often inadequate. We install French drains, dry wells, and grading solutions to redirect water away from foundations.
For homes in flood-prone areas near Johnson Creek or along the Willamette, we incorporate rain gardens with water-loving plants like red twig dogwood. All systems are designed to handle our typical 0.5-1 inch rainfall events while preventing soil erosion.

Frequently Asked Questions
How long do French drains last?
Properly installed with clean gravel and filter fabric, our systems typically function for 20+ years. We include access points for occasional flushing.
