Does anyone know of a supply company(ies) where you can purchase the materials for a basement perimeter drainage system? More specifically, I’m looking for a ridged square or rectangular conduit that sits below the concrete floor so that it channels the water to the sump pit, and that also has an attached flange that extends up above the floor to capture any water that may weep down from the basement wall. I’ve looked on line but all I can find were either second rate DIY systems, or basement water proofing companies, and my supply houses don’t have a line on any of this material either.
Thanks for your feed back.
