ELASTOVAL 4 PL SUPER
Elastomer-Polymer Bitumen Waterproofing Membranes
The waterproofing compound of ELASTOVAL membranes is made up of a mix of empty residue distilled bitumen modified with SBS thermoplastic rubber based on radial elastomers, synthetic rubber and stabilizing aggregate fillers. The compound is thermally stable, very elastic and flexible at low temperatures.
The reinforcement used for ELASTOVAL 4 PL SUPER and ELASTOVAL ARDESIA membranes is made up of a non-woven spundbond polyester mat stabilized with glass fibres, which gives to the product excellent mechanical and breaking elongation characteristics, as well as very good dimensional stability. Such characteristics allow to use these membranes on mechanically and thermally highly stressed surfaces.
The ELASTOVAL 4 PL SUPER membrane is treated on the upper side with non-stick filler; other finishings such as polymeric film and non-woven may also be used. The ELASTOVAL ARDESIA membrane is finished on the upper side either with natural or coloured slate granules or with ceramic granules. The lower side The lower side of both of them is finished with PE torch-on film; other finishings such as aggregate, polymeric films, non-woven non-stick polymers may also be used.
