Newton HydroTank System

The Newton HydroTank System is 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.

This System included a selection of 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.

Combination Waterproofing

For more robust waterproofing protection, BS 8102:2022 recommends combining two or more Types of waterproofing. Newton HydroTank can therefore be combined with our external Type A HydroBond System, our internal Type A HydroSeal System and/or our Type C CDM System.

The Newton Technical Team will work with you to design the right combination of structural waterproofing methods to ensure the end user’s desired internal environment is achieved, in accordance with current legislation and best practice.

Professional waterproofing designers should always consider using more than one type of waterproofing to provide enhanced protection the structure and achieve the necessary environmental grade.
