Solve water problems before they damage your property
What are French Drains?
A French drain is a gravel-filled trench containing a perforated pipe that redirects surface water and groundwater away from problem areas. Named after Henry French who popularized the technique in the 1800s, this elegant drainage solution uses gravity to collect water along its entire length and channel it to a safe discharge point.
French drains work by creating a path of least resistance for water. When installed correctly, water naturally flows into the gravel-filled trench, enters the perforated pipe, and is carried away from your foundation, yard, or other areas where water causes problems. It's an invisible solution that works continuously without pumps or maintenance.
In Oregon, French drains are essential tools for managing our abundant rainfall. Whether you're dealing with a soggy yard, water in your basement, or erosion issues, a properly designed French drain system can transform problematic wet areas into usable, dry space while protecting your property's foundation and landscaping.
Why French Drains Matter in Oregon
Understanding why this service matters helps you make informed decisions about your property.
- Oregon Rain Management: With 40+ inches of annual rainfall in the Willamette Valley, water management is essential. French drains handle our persistent rain by continuously moving water away from vulnerable areas.
- Foundation Protection: Water against foundations causes cracks, leaks, and structural damage. French drains intercept groundwater before it reaches your foundation walls, preventing costly repairs.
- Yard Usability: Soggy, waterlogged yards are unusable for months each year. French drains transform swampy areas into dry, functional outdoor space you can enjoy year-round.
- Erosion Prevention: Uncontrolled water flow erodes soil, damages landscaping, and creates channels through your property. French drains control water flow and prevent erosion damage.

Best Time for French Drain Installation in Oregon
French drains can be installed year-round in Oregon, but the ideal time is during the drier months from June through September when soil conditions are optimal for trenching and gravel work. However, many homeowners discover drainage problems during our wet season--and that's actually a perfect time for assessment, as we can observe exactly where water collects and flows. We can design your system during winter and install it as soon as conditions allow, or proceed immediately with wet-weather installation techniques if your situation is urgent.
