Polythene DPM

by Allco

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

Our Allsheet comes in 2 thickness, 500 and 300 microns.

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