WATERPROOFING RADON GAS BARRIER FOR FOUNDATIONS

RADON FLOOR

RADON FLOOR is a radon and vapour barrier certified by the SP Institut that prevents radon gas from infiltrating the building envelope.
With double reinforcement, it ensures great durability.

It consists of a double layer of low-density polyethylene with reinforcement mesh and high-density polyethylene reinforcement.
It is applied to the inside and outside of walls, in contact with the ground.

It can be applied on various smooth building substrates such as timber, OSB boards without additional surface treatment. The surfaces must be dry, free of dust and solvents such as grease or oil. We recommend the use of PRIMER for rough surfaces such as rough OSB boards. Once the tape has been applied, it is recommended to use the special roller RLL45 to obtain a perfect application.
