Newton HydroBond System

The Newton HydroBond System is a high-performance, Type A waterproofing system designed to be applied to the outside of the structure.

This system can be either pre-applied below the concrete raft/slab and wall building line, or post-applied where conventional formwork is removed to expose the outside of the basement walls.

Depending on the type of structure it is applied to, once installed, the combination of selected products within the HydroBond System can provide a continuous barrier around the full extent of the structure.

The HydroBond System can provide protection against both groundwater and ground gasses such as radon, methane, and carbon dioxide, depending on the products employed, making it the ideal solution where protection from any or all of these elements is required.

External Waterproofing (Type A)

Type A Waterproofing

The British Standard for Waterproofing 8102:2022 is the ‘Code of Practice for Protection of Below Ground Structures Against Water Ingress’ and defines Type A waterproofing as “barrier protection” which is applied to either the internal or external surface of a structure in order to resist the pressure of water trying to enter the building.

Type A membranes are the products that are referred to when people talk about the process of “tanking” a basement in order to protect it from water ingress.

Barrier waterproofing membranes that can be applied to the external ‘positive’ side of the structure include both pre-applied, self-healing sheet membranes, and post-applied liquid membranes that can be linked to the above-ground DPC in order to completely encapsulate, or “tank”, the basement in a continuous waterproof layer.

Combination Waterproofing

Where the assessed risks are deemed to be high or where the consequences of failure to achieve the required internal environment are deemed too high, BS 8102:2022 recommends combining two or more Types of waterproofing. The Newton HydroBond System can therefore be combined with various other Newton systems, including our ‘Type C’ Newton CDM System.

The Newton Technical Team will always ensure the end user’s desired internal environment is achieved with the right combination of structural waterproofing methods 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 to the structure and achieve the necessary environmental grade.

Gas Protection

If protection from ground gases is also a requirement, then Newton will always recommend waterproofing products that also have third-party tested gas resistance. Section 4 of the British Standard for Waterproofing, BS 8102:2022 states that “Strategies for dealing with all external sources of groundwater, surface/flood water, soil gases and contaminants should be determined from the very earliest stages of the planning and design processes for any project involving below ground structures”.

Several of the products in our HydroBond System meet the standards required to protect against both water and below-ground gases. However, suitable products must always be paired with sensible design, and best practice dictates that the most effective combined waterproofing and gas proofing designs always combine multiple forms of protection, and always include ‘Type C’ cavity drain protection, in the form of the Newton CDM System.
