Description

Allsheet is a multi-layer damp proofing membrane manufactured from virgin resin flexible polyethylene. Allsheet has excellent tear resistance and puncture resistance and is highly resistant to acid and base chemicals.

As a damp proof membrane, Allsheet can be for use in low risk / non-hydrostatic conditions, providing some basic gas-barrier properties. Please note that DPM does not form part of Allco's Waterproofing System and is used solely as a damp-proof membrane.

Allsheet 500 (500 micron) is supplied in (flat wound) roll form 2m x 50m
Allsheet 300 (300 micron) is supplied in (flat wound) roll form 4m x 25m
