Radon ADD Waterproofing System

 


 

The Radon Aquis Double Defence (ADD) Waterproofing System has been developed specifically to provide a combined solution for waterproofing and managing the reduction of Radon gas.   By using a combination of physical barriers and air control, this unique system is able to create a safe, dry and healthy living space.

 

The combined process of managing water and radon


Water held within the ground is likely to penetrate into a basement walls and floor slab and so a waterproofing system must be used to protect the interior space from dampness and decorative spoiling. This is provided by methods such as Cavity Drain Membrane and sometimes supported by a Sump and Pump System.  Further details about these methods can be found by visiting our Basement Waterproofing section.

In addition to the waterproofing system, it is recognised that basements are at increased risk of containing high levels of radon.  A system which relies solely on a physical barrier is vulnerable to defects which may allow radon to permeate into the accommodation or cause gas migration to other parts of the property.

To combat this, the ADD Waterproofing system provides the key benefit of using air management components to control the gas that collects by actively venting it to a safe location away from the interior of the property. 

This is done as follows:

 

Positive Pressure Unit
The positive pressure unit installed internally within the basement is a vital part of this system.  It ensures that the air pressure within the habitable space is slightly higher than behind the membrane so that radon cannot be drawn through any minute defects. 

Inline Fan
Any radon which penetrates the basement walls from the surrounding earth is collected behind the waterproofing membrane and evacuated through the inline fan installed within an exhaust pipe which efficiently removed and discharges the gas into the open air at a safe distance from the building.

 

This system also works to control humidity levels in the same way therefore minimising the risk of condensation, lowering the cost of heating as drier air requires less energy to heat) and ensure the air being breathed is clean, fresh and healthy.
