Installation Method
Requires torch-on application (hot-applied). Clean the concrete substrate, ensure it is completely dry, and apply a coat of bitumen primer. Unroll and align the membrane roll. Use a commercial propane gas torch to heat the underside of the roll and the substrate simultaneously. When the thin PE burn-off film melts and a thin layer of glossy molten bitumen appears, roll the membrane forward slowly, pressing down to create a full bond. Seal all overlap joints by hot-melting with a trowel.
Packaging & Loading
Rolls are tightly wrapped with plastic strapping bands, labeled, and vertically stacked on sturdy wooden pallets with protective corner guards and heavy-duty shrink wrap. Loaded securely in 20ft/40ft containers.
Storage & Shelf Life
Store rolls vertically in a dry, well-ventilated, indoor warehouse environment. Keep away from direct sunlight, rain, moisture, and any sources of heat or ignition. Do not double-stack pallets to prevent deformation of the rolls. Shelf life is 12 months under optimal storage conditions.
OEM / Private Label Options
Minor customization (thickness, width, length), Sample-based customization, Full customization (custom branding, private labels, custom cardboard cartons). Minimum order quantity for custom packaging and logos: 2,000 square meters.
