Replacement of a Scupper Drain

Case Study

Old scupper out and new scupper in

Surrounding membrane degranulated and ready for torching

Based in. It is now water proof but still requires the 2nd layer of granular membrane. Not the base membrane does not go to the edge of the patch area. The next layer (granular goes to the edge of the prepared membrane thereby creating a 2ply (2 barrier) system

On this job the scupper drain was replaced. We began by removing the old scupper and installing a new one. The surrounding membrane was degranulated and prepared for torching. It was then based in. With the waterproofing out of the way, it was time to add a second granular membrane layer.
