Im almost up to the waterproofing stage of the bathroom and laundry reno, and have a few questions.
In the bathroom (1950's floating concrete slab), there is a concrete skirting around the edge, which made the installation of the pvc flashing virtually impossible to get flush with the floor. I managed to get it in there but there is a gap between it and the floor. The surface of the slab is also quite poor, with divots etc, so my plan was to screed the slab (and pack some concrete under the flashing in the gap), then waterproof afterwards.
Questions:
- The plumber has installed 2 control flanges on the floor for the 2 drains. What is the best way to screed around these without tipping concrete down the pipe and ending up with a nice finish?
- A builder mate of mine said that since this house is a rental, he would recommend putting the waterproofing under the screed, this way if the tenants chip a tile etc, the waterproofing membrane remains in tact. I just cant see how this is physically possible given the condition of the slab. Thoughts?
Cheers,
