HydroBond 403
HydroBond 403 is a high-performance, self-healing, composite sheet membrane. It consists of a hydrophilic polymer coating on a mesh carrier. It is pre-applied to formwork before concrete is poured, creating a mechanical bond with the wet concrete.
Applications & Uses
- External tanking of basements and substructures - Waterproofing under slabs and against sheet piles - Radon and gas barrier applications
Features & Benefits
- Mechanical bond prevents water tracking between membrane and concrete - Self-healing capabilities for minor punctures - Barrier to Radon, Methane, and CO2 - Can be applied in wet weather
