Water tank & reservoir waterproofing
Tanks and reservoirs hold a permanent head of water against the wall and floor. They need a high-strength, low-permeability cementitious seal applied in extra coats — non-tainting and hard-wearing so it lasts through fill-and-empty cycles.
Recommended Bina systems
Binaseal 1000 Primary
High-strength penetrating cementitious slurry that seals concrete capillaries — also a thin-layer honeycomb repair.

Bina Flexseal 2000 Also suitable
Two-part flexible cementitious slurry — breathable, bondable under tiles and screeds, ideal for wet areas and tanks.
View system →Bina cementitious systems are used for structural water-retaining tanks and reservoirs. For drinking-water (potable) certification, ask us to confirm the current test status before specifying.
