# HDPE Membrane Technical overview ## Roll-supplied polyethylene sheet barriers for below-ground waterproofing and lining Josoor supplies HDPE waterproofing membrane in rolls. HDPE means high-density polyethylene, the polymer used to form the water barrier in the sheet. Building-waterproofing membranes and geomembrane liners use different constructions and joint details: the supplied grade must match whether the project needs structural waterproofing or liquid containment. ### Technical overview Material High-density polyethylene (HDPE) sheet barrier Supply format Waterproofing membrane supplied in rolls Building-waterproofing form Dedicated composite sheet grades can incorporate bonding layers for below-ground concrete construction Containment form Geomembrane liner grades form a continuous lining across the prepared supporting surface Joint formation Bonded overlaps for applicable composite building membranes; thermal-fusion seams for weldable geomembrane liners Supporting build-up Prepared support, detailed penetrations and specified protection against construction damage ### Typical applications by grade - Below-slab and basement-wall waterproofing using a dedicated building-waterproofing sheet grade. - Foundation and below-ground concrete protection within the specified structural-waterproofing system. - Pond, reservoir and canal lining using a suitable geomembrane grade. - Landfill barriers and secondary containment using a liner specified for the stored liquid, exposure and engineering design. A bare HDPE geomembrane is not automatically a bonded basement membrane. Chemical exposure, potable-water contact, UV exposure and containment duty require the appropriate grade and supporting documentation. Tell us whether the project is building waterproofing or containment, plus the area, exposure and required thickness, for an HDPE membrane roll quotation and product data sheet.
