Geotech RB

GEOTECH RB (RADON ADVANCED BARRIER) is made of a special elastoplastomeric compound based on distilled bitumen, plastomers, and elastomers. It is extremely compact, without free volumes, and thus impermeable to gases.

The reinforcement of the GEOTECH RB membrane consists of an elastic, puncture-resistant, “non-woven” polyester fabric. The reinforcement in GEOTECH RB consists of a rot-proof fiberglass mat coupled with aluminum foil that forms another barrier that is practically impossible for the RADON to penetrate. The upper face of the membrane is coated with serigraphs talc, which makes it possible to quickly unroll the rolls. The underside of the membrane is coated with Flamina, a plastic film that melts when torched and which is embossed with squares to allow the optimal retraction of the film and indicates the correct bonding temperature. Barrier continuity is obtained by torch-welding membrane overlaps. GEOTECH RB’s permeability to RADON is adequate for almost all applications because the partial pressure of RADON is generally just a few thousandths of a bar. Special situations may require the use of GEOTECH RB, which has such a low permeability to RADON that it can be considered a total barrier.

Application Fields:

RADON BARRIER membranes are used to cover vertical and horizontal elements of new buildings that are in contact with the ground. On the wet ground or near the water-bearing stratum, GEOTECH RB membranes are also used as the first layer of a waterproofing system consisting of two membrane layers.

Advantages:

  • GEOTECH RB membranes are multifunctional, providing protection from both RADON and water.
  • Unlike other systems, unbroken protection is provided because the overlaps can be welded.
  • Compared to other sheets, they are strong, resistant, and extra-thick and thus resist puncturing.
