Cementitious waterproofing

A system choice for concrete tanks, pools, bathrooms and selected below-grade details

Where it works

Cementitious systems bond well to mineral substrates and can be practical in wet rooms, concrete tanks and pools when the product is approved for the intended exposure.

Movement matters

Rigid products are less tolerant of movement. Cracks, joints and transitions may need flexible reinforcement or a different membrane system.

Before covering it

Follow substrate preparation, curing, layer thickness and flood/holding tests required by the manufacturer before tile, backfill or protective layers are installed.
