riser wrap

A two-layer protective pipe wrap consisting of an adhesive liquid covered by a heat shrink sleeve

The Riser-Wrap® seal is a two-layer system designed for corrosion and sealing protection on pipelines and encapsulating manholes to seal joints against ground water infiltration.

The first layer is a visco-elastic adhesive liquid sealant covered by a heat shrink sleeve. The sleeve is a thick-walled (2.5mm), cross-linked, high density polyethylene membrane.
