Radon Protection


Basements

In radon-risk areas basements can be found to contain particularly high concentrations of radon. 

This is because radon gas is heavier than air and will therefore have a tendency to accumulate at the lowest level of a building.

Basement Radon Protection

In some cases, the basement tanking system will provide adequate protection against the radon ingress. However, where a radon measurement reveals levels of radon above the recommended action level, remedial measures will usually be required. The BRE identify six main methods of reducing the amount of radon entering a house with a cellar or basement.

Ways to Reduce Radon Intrusion

  • Installing a radon sump system

  • Sealing floors and walls

  • Increasing underfloor ventilation

  • Installing whole house positive pressurisation or positive supply ventilation system

  • Improving ventilation of the house

  • Improving ventilation of the cellar or basement

Sump Pump Radon Mitigation System

A simple way of combining the first three of these methods is to install a cavity drainage system such as Oldroyd Xv Clear connected to a modified sump system designed to pump both water and radon away from the basement. An example of such a radon mitigation system is shown to the left. 

Oldroyd Xv Clear is a semi-transparent, studded cavity drainage membrane manufactured from polypropylene. 

It is specifically designed for application to damp/contaminated internal floors and walls, and is particularly useful in basement waterproofing and conversion applications.
