Bentonite waterproofing pad
Sodium-bentonite geotextile laid against blinding or fastened to the wall face; swells on contact with water to seal itself and minor concrete defects. Laps 100 mm.
APP membranes (torch-on applied)
Modified-bitumen sheet torch-applied to a primed deck. Requires a hot-works permit and a dry substrate; unbeatable on large uninterrupted decks.
Self-swelling water stop
Hydrophilic profile nailed into cold joints and around penetrations before the pour. The detail that decides whether a basement leaks, not the membrane area.
