Integral Type B Waterproofing Products

Newton HydroTank products are an integral Type B waterproofing solution - for projects that require the below-ground structure itself to be integrally waterproof and to act as the primary resistance to water ingress.

Products include BDA certified waterbars, waterstops, flanges, sealants and capillary blocking treatments that are used to seal the joints and penetrations through the concrete and achieve an effective Type B solution.

Type B Waterproofing

British Standard 8102:2022 defines Type B waterproofing as designing the structure itself to be integrally waterproof and the primary resistance to water ingress.

Nothing provides better primary resistance to water than a well-designed and well-placed reinforced concrete structure, designed in accordance with BS EN 1992 with sufficient steel reinforcement to limit flexural and sectional cracking and therefore produce watertight concrete elements.

The use of correctly designed and installed waterbars at the places where the concrete isn’t, such as at joints and penetrations, will result in a Type B structure that should be fully watertight.
