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 polymer-bitumen compound. Once applied, GEOMAT RR forms a continuous barrier against roots. As it does not contain film or double-reinforced foils, GEOMAT RR is more flexible and malleable during application. The additive has been developed specifically as a root inhibitor, for both hot-laid bitumen,s and for torch-laid bitumen membranes. The product comes from thirty years of German experience in the waterproofing industry.
GEOMAT RR is made up of distilled and selected bitumen for industrial use containing a high quantity of elastoplastomeric polymers such as to obtain a “phase inversion” alloy. The continuous phase of this alloy consists of the polymer in which the bitumen is dispersed, where the characteristics are determined by the polymer matrix and not by the bitumen, even if it is the largest ingredient. The performance of bitumen is therefore increased, durability and resistance to high and low temperatures are improved, thus maintaining the bitumen’s already excellent qualities of adhesion and waterproofing. The reinforcement of the membrane consists of a single strand of Spunbond nonwoven polyester fabric, with a high basic weight (grammage). This fabric is isotropic, rot-proof, thermally fixed, and boasts high mechanical resistance, considerable ultimate elongation, excellent resistance to punching and laceration.
GEOMAT RR has both faces coated with Flaminia, the hot-melt film, which stops the rolls of material from sticking together. The light blue mark on the film that covers the lower face, outside the roll, distinguishes the root inhibitor membrane from the other membranes, so that it is recognizable even for sections of rolls in which the packaging tapes with the description have been removed. The reinforcement and the waterproofing mass are resistant to chemical effects of humic acids and fertilizers. GEOMAT RR is used in all waterproofing systems in contact with the ground or where there is the risk of the system being attacked by roots.
