Weberdry HDPE

Weberdry HDPE is mainly composed of high-density polyethylene (HDPE) sheets, high-polymer self-adhesive layer and surface anti-adhesivity (or adhesivity-reducing) release liner.

Weberdry HDPE is suitable for floors of underground works, side walls involving installation by use of the 'External Waterproofing and Internal Applied' technique in underground works, tunnels, etc. Before the initial setting of the post-cast concrete, the concrete gradually cross-linked and meshes with the self-adhesive layer of the membrane under the action of gravity, and the physical absorption and mortise-tenon effects are generated during the cement curing process, so that the membrane and the post-cast concrete are firmly bonded to each other and not easy to be separated.
