HydroCoat Tanking Slurry
- Simple Defence, Strong Bond: HydroCoat Tanking Slurry is a high-performance tanking slurry and single-component cementitious waterproof coating. It resists positive and negative hydrostatic pressure while forming a strong, durable bond to concrete and masonry.
- Two-Coat Powerhouse: Applied in two coats, the slurry forms a 2mm waterproof barrier. Consequently, it resists water pressure up to 7 bar while actively sealing developing micro-cracks within the substrate.
- Versatile Damp-Proofing: HydroCoat Slurry adapts to a wide range of substrates. Therefore, it protects against pressurised water and ground moisture in both internal and external damp-proofing applications.
- Professional System Integration: The slurry supports coordinated Type A waterproofing design. It integrates with compatible protection layers and detailing systems to improve continuity, durability, and long-term performance in retained structures.
Cementitious Tanking Slurry – Technical Overview
HydroCoat Tanking Slurry is a single-component, mineral-based coating that installers mix easily with clean water. The slurry is applied by brush, trowel, or spray and performs reliably on damp substrates.
Unlike conventional tanking slurries, HydroCoat Tanking Slurry contains advanced crystallising and capillary-blocking chemicals. These penetrate the substrate, enhance bond strength, and react with moisture and calcium hydroxide within concrete.
Applied internally or externally, the cementitious coating forms an effective barrier against positive and negative hydrostatic pressure. It also protects against non-pressurised ground moisture for dependable damp-proofing performance.
When applied in two coats, the 2mm system achieves waterproofing resistance up to 7 bar. The penetrating crystallising chemicals actively seal micro-cracks, improving structural durability and long-term performance. This HydroCoat slurry forms part of a Type A waterproofing system and complies with BS 8102:2022 for Grades 1, 2, and 3 environments. The product holds BBA Certificate 23/6962 and is accepted by the NHBC for both habitable and non-habitable structures.
The product is supplied in bags or bag-in-bucket packaging, allowing flexible handling and on-site part-mixing.
