The membranes are made up of distilled bitumen selected for industrial use, with elastomeric and plastomeric polymers added to obtain a phase inversion compound whose

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

GEOMAT RR is a root-resistant waterproofing membrane. The anti root properties are obtained by adding phenoxifatty acid ester, a specific anti root agent, to the

GEOTECH DE is the membrane that insulates rails from electrical currents and stops the dispersion of current to the ground. GEOTECH DE has a very

GEOTECH FS are fire-resistant membranes with harmless inorganic anti-flame additives distributed right through the membrane. The GEOTECH FS membranes are the result of research activities
