A non-woven geotextile filter layer thermally welded to a water impermeable HDPE (high density polyethylene) drainage membrane.
A two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable high-density polyethylene (HDPE) drainage membrane.
The product provides drainage and protection to the outside face of basement walls to sloping sites, preventing the build-up of water pressure and protecting the structure from aggressive water, chemicals and toxins, and provides mechanical protection only when used against the ‘Type A’ waterproofing where the site is not sloping and so where ground water removal is not viable or recommended.
Consult manufacturer's literature for relevant installation information.
