Commercial waterproofing grade products use patented expandable bi-fold technology to absorb the common wave deformity generic dimple mat can’t overcome. Our system allows us to work smarter and faster with the horizontal troughs and structural footer dimples. This design allows us to yield higher drain allowance & clog-free seepage collection benefitting for all our commercial contractors.
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 will 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.
