Do I need a waterproof membrane?
I am looking to get a tiler to repair my shower which has been leaking through the grouting. If I get the whole shower retiled, would it be a good idea to get a waterprooof membrane?
Expert Trade Answers
"If the tiles are on plasterboard then I recommend re boarding it with wedi board and tank the joints with mapai waterproofing kit.
If you want to boarding it with plasterboard then you tank the joints the same way as wedi but you also tank the face of the boards too as they’re are not waterproof."

"Hi David, it's a wet area so yes definitely. I recommend Mapei or Ardex. Schlutter is best, but too expensive.
More importantly before you start, be 100% sure you've identified the leak cause."
