Audited Supplier GM13 HDPE Membrane for Landfill Pond Liner
First of all, make preparations to clean, roll and flatten the surface of the base layer to be laid; then take
the materials locally and fill the surface of the base layer with an excavator. The filled layer is not less than
30 cm thick and there is no loess If you want, you can use yellow sand or fine sand instead, fill up the soil
layer or sand layer, compact the soil protection layer, prepare for the next step, dig underground water to
guide the drainage, and distribute the drainage pipes.
Secondly, the soil protection base layer should be leveled and tamped, and the surface should be smooth
and smooth, and there should be no gravel over 2cm or obvious small pits; after checking that there is no
problem, the bentonite waterproof blanket will be naturally relaxed and flat Lay on the soil protection layer
with the non-woven fabric facing down and the woven fabric facing up. Note: The construction of bentonite
waterproof blanket should be carried out in rainless and snowy weather. In case of rain and snow, the plastic
film should be used to prevent the swelling of the bentonite in the waterproof blanket. The overlap of the
bentonite waterproof blanket is not less than 20 cm. Sprinkle bentonite lap powder evenly on the lap edge,
spray it to make it compact after pressing, and keep it flat. After laying, check the waterproof blanket for
damage and holes, repair it in time, and prepare for the next step.
In the 1980s, HDPE high-density polyethylene geomembrane, also called HDPE anti-seepage geomembrane,
also called anti-seepage membrane, was used in anti-seepage projects in landfills. With China's emphasis
on ecological environment and the increasing awareness of national environmental protection, anti-seepage
membranes are widely used in landfill disposal. Lay the HDPE impermeable membrane on the bentonite
waterproof blanket, stretch it flat, without large air bubbles, flatten it, and avoid heavy machinery such as
excavators rolling, turning or walking on the impermeable membrane; impermeable membrane and
anti-impermeable membrane The lapped edge of the membrane should be no less than ten centimeters,
and the edge should be kept clean and free of debris and stones; then prepare for welding. Before welding,
take two pieces of geomembrane of about one meter for test welding, adjust the reasonable temperature
of the welding machine, and then use a professional Welding personnel welding; welding should be carried
out simultaneously with the laying of impermeable membrane until the laying is completed. Note: During the
laying of the geomembrane, the excavator will cover the geomembrane slowly and evenly with soil on the side.
Welding and filling are carried out simultaneously to avoid artificial damage to the geomembrane; the protective
soil layer on the geomembrane is not lower than Thirty centimeters thick to prevent plant roots from piercing
the geomembrane, and then the soil is compacted.
Manufacturing Technique
HDPE Geomembrane liner are made from polyethylene polymer materials by the film-blowing
process.it is most widelyused for solid waste containment (such as landfill liners), mining and
water containment applications.
