Waterproofing Basements and Foundations (Brush or Poured)
Below ground, water is relentless. Basements, foundations and retaining structures need a tough, flexible waterproof coating that bridges cracks and moves with the structure — because a rigid system that cracks is a system that leaks.

The challenge below ground
Ground water exerts constant pressure, and any breach below ground lets water track in — hard and costly to fix after the fact. BS 8102:2022 is the code of practice for protecting below-ground structures; habitable space typically needs Grade 3 (a dry environment), which demands a reliable, continuous waterproofing system.
The solution: The GOAT (7.5kg)
The GOAT (7.5kg) is a flexible, crack-bridging waterproof coating that can be brushed or poured onto basements, foundations and below-ground structures. It forms a seamless, durable waterproof layer that moves with the building rather than cracking — with no laps or joints to fail.
How it is applied
- Prepare a sound, clean substrate
- Detail junctions and kickers first
- Brush or pour to the required film thickness
- Build up as a continuous, seamless barrier
Benefits
- Flexible and crack-bridging
- Brush or pour application
- Seamless below-ground waterproofing
