Elastoflex® SA Base membrane is a premium, self-adhered elastomeric base membrane, manufactured using patented ADESO® dual-compound self-adhesive technology, whereby a “true” Styrene-Butadiene-Styrene (SBS) modified asphalt compound is applied on the top layer and an aggressive self-adhesive compound is applied on the bottom layer. Elastoflex SA Base membrane has a high performance reinforced polyester mat to enhance puncture resistance and dimensional stability.

Elastoflex SA Base membrane is finished with polyolefin film having laylines on the top surface and a split release film on the bottom surface.
