MAMMOUTH® 40 VR is a flexible oxidized bitumen waterproofing membrane with glass fleece reinforcement (according to NF P 84.314). The topside is protected by fine sand and the underside by a thermofusible film.
SOPREMA was the inventor of the famous MAMMOUTH® membranes, in the early 20th century. Even If this brand, owned by SOPREMA has become a generic name, oxidized bitumen membranes, give way to membranes using an elastomeric bitumen (Sopralene®, SOPRALAST®, ...).
MAMMOUTH® 40 VR is to be used as a first or secondary layer under protection in all two-ply elastomeric, plastomeric or oxidized bitumen waterproofing systems. MAMMOUTH® 40 VR must be applied only by heat welding or torch- on techniques for the underside (film). Upperface will be laid by torch-on techniques, hot bitumen or by cold bonding SOPRACOLLE® 300 N onto a compatible surface.
