NEW for 2020!
Not every job needs the flange. You only need a flange if you have water running down the inside face of the foundation wall and are NOT using a drainage membrane over the internal wall surface.
Installing Flangless Waterguard is less expensive and easier, so if you don't need the flange you no longer have to pay for something you don't need!
A 3ft9" length costs only $7.99 per ft!
