COMPOUND
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.
REINFORCEMENT
The reinforcement used for ELASTOVAL MINERALE VV membranes is made up of a reinforced glass fiber which gives to the product
remarkable mechanical characteristics, sufficient breaking elongation, as well as excellent dimensional stability. Such characteristics
allow to use these membranes on non-particularly stressed surfaces.
OUTSIDE FINISHING
The ELASTOVAL MINERALE VV membrane is finished on the upper side either with natural or coloured slate granules or with ceramic
granules. The lower side is finished with PE torch-on film; other finishings such as aggregate, polymeric films, non-woven non-stick
polymers may also be used.
LAYING METHOD
The laying deck shall be clean, smooth and dry. For a better adhesion it may be previously treated either with VERVAL PRIMER
(solvent based) or with ECOPRIMER (water based). The membrane is then laid by melting the lower side with light propane gas flame.
Edges shall be overlapped, always by torch, by at least 10 cm. on the sides and 15 cm. on top so that the roofing watertightness is
