2 Component Cementitious Waterproof Coating
TM Cemblock
Rated for water pressure from either direction.
Overview
TM Cemblock pairs a liquid binder (Component A) with a cementitious powder (Component B), mixed on site at 1 part liquid to 1.5 parts powder, into a flexible membrane that bonds directly to the substrate.
Because it's rated for both positive and negative-side hydrostatic pressure, it covers the two situations most waterproofing systems have to choose between: a water tank pushing outward, and a basement wall with groundwater pushing in.
That range is why it shows up across such a wide spread of applications — wet areas, water tanks, terraces, basements, podiums — anywhere a single flexible cementitious system needs to hold against water from whichever side it's coming from.
Key features
- Rated for both positive and negative-side hydrostatic pressure
- 2-component cementitious system, mixed on site
- Elasticity up to 150% — bridges minor substrate movement
- Specified for wet areas, water tanks, terraces, basements and podiums
- Bonds directly to the substrate — becomes part of the structure
