Your Foundation

Protect what holds everything up.
French Drain Replacement
Collapsed, blocked, or past its prime? We inspect with a camera, dig where it's needed, replace the entire system and finish with proper backfill and site restoration. Say goodbye to moisture with a drainage system rebuilt from the ground up.

Polyurea Membrane
We apply the polyurea membrane in-house, no subcontracting. The result is a hot-sprayed waterproof barrier, perfect adhesion to concrete, and full quality control on our end. Ideal for new builds, foundation renovations or existing water infiltration.

Camera Inspection
Before we dig, we look. Our camera inspection pinpoints infiltration, blockages, and cracks in your pipes and foundation. This means no demolition, no guesswork, just a clear diagnosis and report.

Sump Pit and Sump Pump
We install the right duo to keep water away from your foundation. The sump pit collects water that builds up around the structure, and the pump automatically drains it out as soon as levels rise.

Crack Repair
Even a small crack is rarely harmless. We repair by injection or sealing to stop infiltration at the source and preserve the integrity of your foundation. Count on protection against water damage, mould, and structural weakening.
