Brick Bat Coba: The Traditional Terrace System That Still Wins
Long before liquid membranes, brick bat coba was protecting terraces across India — and done properly, it still outperforms many modern shortcuts.
How the system works
Brick bat coba waterproofing builds a protective mass over the slab in layers:
- A primer coat locks the system to the cleaned slab.
- Broken bricks are laid evenly to create slope and a strong, insulating base.
- Waterproof cement mortar fills every gap into a single solid layer.
- A protective coating or plaster finishes the surface.
Why it lasts
The thickness and mass make it highly resistant to foot traffic, thermal movement and mechanical damage — the things that crack thin coatings. As a bonus, the layered structure provides thermal insulation, keeping the floor below cooler.
When to choose brick bat coba
- Terraces that take regular foot traffic
- Roofs where you also want heat insulation
- Structures needing a robust, long-life system
It pairs well with a reflective thermal coating on top for extra heat control, or sits within a complete terrace waterproofing system.
