For a safe basement, ADD Waterproofing

Aquis Double Defence, or ADD, is a unique combined waterproofing and radon gas control system. It has been developed as a system to provide safe waterproofing for basements or other below-ground areas.

Due to having several surfaces in contact with the ground, The Health Protection Agency advises that all basements are susceptible to the accumulation of high concentrations of the naturally occurring radon gas.

Radon management is a sophisticated process. Without an understanding of the science of radon, methods used for waterproofing can in fact elevate levels of radon in a property, or move the gas to another area of the building, increasing the risk posed to the occupants. Radon management should only be undertaken by competent and trained specialists.

Why use Aquis Double Defence?

Over 2000 people in the UK die from radon-linked lung cancer every year

ADD is the only system that will control concentration of radon gas in basements and achieve waterproofing to BS 8102 standard

Suitable for basement conversions and newbuild

Aquis Double Defence is the only system available that will enable a basement to be dry and safe to occupy.
