Updated: Apr 17, 2020
Poor preparation – Any issues with waterproofing commonly stem from poor preparation and planning.
Before waterproofing, the surface should be completely dry. Moisture being present can compromise the effectivity of any waterproofing applied.
Failure to caulk / mastic
The sole purpose of the caulk / mastic is to seal the joints in preparation for the membrane.
Failure to prime
Aside from ridding the surface of moisture, it should also be primed. Otherwise, the waterproofing solution will be uneven and won’t adhere efficiently
Failure to upturn your membrane
The upturn is a vital part of waterproofing, at the point of the upturn, if it is not waterproofed the floor membrane will be comprised and moisture will penetrate the floor membrane.
