French Drains in Port Coquitlam, BC

A French drain is a gravel-filled trench with perforated pipe that intercepts water before it reaches a structure or a low spot. Curtain drains across a slope and channel drains at driveways are the two most common variants here. Flat, low-lying neighbourhoods near the Pitt and Coquitlam rivers put pressure on perimeter drains and sump systems during heavy winter rain.

Where they work

Uphill of a house on a sloped lot, along a property line receiving a neighbour's runoff, or across a driveway or walkway that channels water toward the garage.

Build quality matters

Filter fabric, washed drain rock and proper fall are what separate a drain that lasts twenty years from one that silts up in three.

Discharge point

Every French drain needs somewhere to go — a storm connection, a dry well, or daylight at a lower point on the property.
