Hydroprufe 300R is manufactured from a blend of polymer films that is suitable for use in the protection of buildings from the ingress of radon gas. Hydroprufe 300R also acts as a damp proof membrane but is not intended for use where there is a risk of hydrostatic pressure. It is installed in a similar way to a damp proof membrane, but with much greater attention paid to workmanship and detailing in order to achieve effective sealing at all locations.
Hydroprufe 300R is designed to protect structures and occupants from gases that may be existent in the ground conditions, on low to medium risk characteristic sites. It is laid beneath concrete to act as a gas-resistant membrane whilst also acting as an effective damp proof membrane to prevent the ingress of water.
