What is Radon?
Radon is quite simply a naturally occurring radioactive gas. It has no colour, taste or smell. Radon is created by the decay (or break down) of the small amounts of radioactive uranium that occur naturally in all rocks and soils.
Radon in Buildings
Radon and other ground gases, such as methane, are now more recognised as contributors to health and safety in buildings – and especially basements. Those designing basement systems or in fact any below ground structure must consider the possibility of ground gases in any design, this is now a requirement of Building Regulations and the relevent Codes of Practice. A desk based on-line search can be done to locate the risk of radon at your property. Cook Group can do this for you as part of our design service for a structural waterproofing system.
The outcome of any radon search will categorise the ground around the property in 3 ways
- No action required
- A basic radon barrier system installation required
- A full positive ventilation radon control system installation required
The latter two require the introduction of additional materials and installation techniques to create a system to provide the level of protection designated. The positive ventilation system requires additional components to force air to move behind membranes to extract ground gases, such as radon. These systems have additional costs over and above standard basement water proofing, but the costs can be controlled by designing in ground gas control as an integral part of the water proofing system.
