ABOUT GAS PROTECTION SYSTEMS

Gas protection systems are used mainly to protect against the effects of radon gas. Radon is a poisonous, heavy, radioactive gas which is emitted from granites. Radon gas protection can be provided either by a gastight underlay below the ground slab, or by the ventilation of the under floor space into a radon sump. For maximum protection both techniques can be used together.

The gas protection sump should be located as close as possible to the centre of the floor plan of the building. One gas protection sump is sufficient for approximately 250m².The sump should be connected to sealed pipework routed vertically through the building. This should discharge to fresh air at high level.
