Professional French Drain Installation Across BC
A French drain is a trench filled with gravel and a perforated pipe that collects and redirects groundwater away from your foundation. In BC's wet climate, French drains are one of the most effective solutions for persistent basement and foundation water entry. Our assessment begins with a site evaluation including groundwater conditions, soil type, grading, and existing drainage. We design the French drain system to match your property's specific conditions, install the trench with proper slope, gravel, filter fabric, and perforated pipe, and connect the system to an appropriate discharge point. The result is reliable protection against groundwater pressure that causes basement seepage.
Frequently Asked Questions
How deep should a French drain be installed?
French drains around foundations are typically installed at the footing depth (30-60 cm below grade) or deeper depending on the groundwater table. We determine the appropriate depth based on a site assessment.
How much does a French drain cost in BC?
French drain installation typically costs $50-$100 per linear foot depending on depth, soil conditions, and access. We provide transparent quotes before starting work.
