Radon is formed by the radioactive decay of small amounts of uranium that occur naturally in all rocks and soils. Found in very low concentrations in the air we breathe, under normal circumstances the risk to our health from radon is minimal. It is an odourless, colourless radioactive gas – we can’t see it, smell it or taste it. Radon is heavier than air making basements particularly vulnerable to higher becquerel levels (the technical measurement for radon), which can become a risk to health.

Properties with basements or cellars, or those built into a hillside are at higher risk of radon as there are extra surfaces in contact with the ground through which the gas can permeate. Where there is a high risk from radon, we are able to very neatly tie gas-proofing the structure into our waterproofing technology.

Stonehouse install the Newton PAC 500 cavity drain membrane system together with a Prestige Air positive pressure air delivery system. This manages and removes radon as well as other potentially harmful ground gases.

As part of the waterproofing system installation all joints and fixings are also tracer gas-tested to provide a gas-tight barrier. This complies with BRE Guidance Paper 211 (Radon Protection for new Buildings).

The following case studies include examples of projects where we included radon control measures in our main basement waterproofing system. Please contact us to discover how we can help you.
