WHAT WE DO
French drains, period. Total specialization means flawless execution, from diagnosis to backfilling.
Dangers of a Faulty French Drain
An effective French drain is crucial for preserving your home's structure and health. A faulty system can lead to serious problems: water infiltration that threatens the foundation and creates an environment ripe for mould.
- Water infiltration in the basement and garage
- Mould and risks to respiratory health
- Foundation degradation and structural cracks
New Installation
For residential construction. Perimeter French drain compliant with the Building Code, non-woven geotextile, and 3/4-inch clean stone.
Complete Replacement

Diagnosis
SIGNS YOUR DRAIN IS FAILING
Spot these symptoms before they become a costly disaster.
Water in the Basement
Recurring infiltration, especially during thaws or after heavy rain.
Efflorescence
White, powdery deposits on the foundation's concrete, a sign of chronic moisture.
Active Cracks
Cracks that are widening, visible seepage, or damp stains on the wall.
Floor Drain Backups
Water backing up in the floor drain or persistent odours in the basement.
Slab Heaving
Excessive hydrostatic pressure under the concrete slab.
House Older Than 30 Years
The useful life of a French drain is 30 to 40 years. Beyond that, the risk of failure increases.
