Over the past 10 years we have successfully installed over 4000 basement drain systems. Our process and design takes more time, labor and materials and results in a better outcome. This is why we are able to offer our lifetime warranty.
At Drycrete we start by using a jack hammer to create the perimeter trench. The reason for jack hammering instead of saw cutting the trench is that the concrete will bond better to the existing floor if there is a rough edge vs a clean cut line. Once the concrete is removed the trenches are dug roughly 10-18” deep, varying in depth to pitch water towards the sump pump container location and ensure we capture the full amount of water. Once the trenches are dug, 3/4” washed stone is installed as a base approximately 2-4” thick. Then a 4” perforated triple wall PVC pipe with perforated holes is installed pitching towards the sump pump container. Polydrain DryCove lower wall wrap is installed after the perforated pipe and before additional 3/4” stone is installed over the pipe. Before re-pouring the concrete it is important to go around and stamp down the 3/4” stone to ensure there are no voids or gaps around the trench. Fresh concrete is then mixed and poured on site in the basement. We pour roughly 3” thick concrete over the open existing trench, pipe and crushed stone and against the dry cover lower wrap. Initially the concrete is going to look like a dark charcoal color but overtime it will cure and blend with the existing floor.
