French drain system is our rugged stand-alone footer system – offers superior protection against basement water seepage in one easy installation. Our French Drain innovational design incorporates the subfloor system with wall drainage. Water enters the system through the whole tapped into the base of the walls and flows through the French Drain System to the sump pump.
To install an interior French drain system, as a professional waterproofing contractor, we cut a channel into your basement slab around its perimeter. Excavates the ground below the channel, installs perforated drain pipe and a sump pump well, and fills the trench with drainage gravel. The slab is patched with fresh concrete.
1. Start by installing the sump pump system first (if needed in your situation), we can also connect to existing sumps as long as canister meets requirements. This will help manage water flow during the process of breaking out the concrete along where the floor and walls meet.
2. Beginning at the sump pump, we remove concrete floor away from the walls and all the way down to the footer.
3. We then precisely grade the French drain on the footer and verify that the vertical portion of the system will stick up above the floor surface a quarter inch to 1-inch after the cement work is finished.
4. Seems between the main sections should be covered to keep concrete from getting into the system while pouring concrete.
5. Once the system is completely laid out and seems taped, we pour crushed rock into the trench, filling up to the horizontal plane of the top of the French drain system. This will leave allow space to pour concrete yet over the channel allowing for the back fin to stick up above the concrete and catch any water that may come down the wall through cracks or window wells.
We use highly sophisticated drain main system, a rugged stand alone waterproofing system designed to trap the hydrostatic pressure with two rubber seals and uses hydrostatic pressure to drive water seepage towards the sump pump.
Our system solves the leakage problem with a leak guard acting as a secondary channel that keeps water from building up and under the seam between the floor and new cement.
