TL-32007 Polymer (HDPE) Resin Waterproof Sheet

Product Overview:
HDPE waterproof sheet is a high-density polyethylene resin-based waterproof material. It is produced using ethylene as the main raw material, with propylene, 1-butene, and hexene as comonomers. This material is suitable for thermoplastic molding processes and offers excellent molding processability.
 
Product Features:
High Tensile Strength: Over 16MPa at room temperature; elongation at break exceeds 550%.
Excellent Low-Temperature Flexibility: Remains flexible below -35°C.
Soft Texture: Good adhesion to the base surface, easy to lay and install.
Chemical Resistance: Resistant to acids, alkalis, and various chemicals.
Environmentally Friendly: No volatile solvents or toxic gases.
 
Applications:
Roof Waterproofing: For buildings' basements, underground warehouses, and garages.
Municipal Projects: Urban landfill, ash dam handling, roads, railways, drainage projects, water conservancy, and tunnels.
Waterproofing Dams and Reservoirs: Including liquid storage tanks, water, oil, and liquid transport channels, solid waste disposal sites, cofferdams, land reclamation, and dock projects.
Construction Instructions:
 
Base Requirements:
The base surface should be smooth and flat, free of sand, voids, and bumps.
Corners should be rounded or beveled.
The base must be inspected and approved.
 
Process Flow:
Base Surface Cleaning: Ensure the surface is clean and smooth.
Sheet Laying: Position the HDPE sheets according to marked lines, ensuring the sheets are flat and aligned, with an overlap width of at least 80mm.
Seam Welding: Weld each seam using a welding machine. If using double seams, perform air pressure testing.
Node Repair: Weld suitably cut sheet pieces to the main sheet using a handheld welding gun.
Sheet Edges: Fix the sheet edges with pressure strips and seal with sealant.
Detail Treatment: Follow the procedures in the national standard drawing collection 16CJ23-3.
 
Precautions:
Construction temperature should be above -5°C.
Ensure construction protection and temporary fixation before the end of daily construction.
The waterproof layer should be applied after the previous process is completed to avoid cross-construction.
Store the product on a flat, water-free ground, with a stack height of no more than four rolls. Cover with opaque material for storage.
Ensure good ventilation at the construction site and storage area, and prohibit smoking and fire. Take fire precautions during transportation.
Under normal conditions, the storage period is 12 months from the production date.
