French Drains
Subsurface drainage that redirects water away from your foundation before it becomes a moisture problem.
What's Included
Included in this job
- Site water-flow assessment
- Trench excavation along the drainage path
- Perforated pipe and gravel drain installation
- Proper slope for gravity drainage to a safe discharge point
- Integration with sump pump or downspout systems where relevant
- Surface restoration after installation
Who It's For
Homeowners with water pooling near the foundation, yard drainage problems, or as a preventive measure alongside other waterproofing work.
A French drain is a gravel-and-perforated-pipe trench that intercepts and redirects groundwater or surface runoff away from a foundation before it can build up pressure or find its way inside. We design and install French drain systems around the actual water patterns on your property — surface grading, snowmelt runoff paths, and monsoon drainage all factor into placement.
Common Questions
French Drains FAQ
Where does the water from a French drain actually go?
It's routed by gravity slope to a safe discharge point away from the foundation — a storm drain, a lower part of the property, or a dry well, depending on what your site allows. We plan the discharge point as part of the design.
Can a French drain handle monsoon-level rainfall?
A properly sized and sloped system is designed around your property's actual water volume, including heavy monsoon events — sizing and slope are part of what we assess before installing.
