Membrana HDPE liner is produced from high-density polyethylene resin. The manufacturing process involves film-blowing, adding carbon black, antioxidant, anti-aging, and UV-resistance components to form a sheet. Smooth membrana liner is the low permeable synthetic membrane liner and geotechnical engineering materials which are widely used for solid waste containment, mining and water containment applications.

Mining is a heavy pollution engineering project, whether it is raw materials or products, are dangerous goods that have great harm to the environment. If there is no good protection measures, once the toxic pollutants leak, it will lead to groundwater pollution, a serious threat to environmental safety. Australian customers decided to lay a layer of protective geomembrane to prevent seepage after the mining excavation. However, due to the complex terrain of the construction site, the construction is relatively difficult.

Membrana HDPE liner is the kind of anti-seepage geosynthetic material which is widely used for waste containment, water containment, aquaculture, industrial project, energy project and mining project, etc. HDPE geomembrane liner material has the characteristics of anti-seepage property excellent chemical resistance, outstanding stress cracking ability, low permeability, good UV resistance and low temperature resistance to brittleness, etc. so the Membrana HDPE Liner is the most widely used for many kinds of anti-seepage bottom pond lining and covering applications such as  landfill project, biogas digester projects, sludge and sewage treatment facilities, evaporation ponds for animal manure facilities such as dairy farms and pig farms and chicken Farms.

For this, BPM engineers built HDPE slope protection technology. The principle of HDPE geomembrane slope protection and reinforcement technology in complex broken open slope is as follows. Membrana HDPE liner can prevent rainwater from entering the soil and prevent loose soil from affecting soil under the action of rain. Strength and stability, to prevent the sliding surface mechanical parameters reduce or the increase of self weight lead to the decline of slope stability and overall sliding. Through the application of HDPE membrane liner slope protection and reinforcement technology in the complex broken open-pit slope, even if there is a large range of through cracks in the slope under the action of rain, it can also prevent the slope from sliding.


HDPE geomembrane is specially designed and fabricated for landfills and mining applications due to its advanced stabilization, excellent inherent flexibility. HDPE geomembranes accompanied with geotextile have been widely in backfilled liner, retaining backfill on steep side, heap leach pads, landfill and pad base liner, water conservancy applications such as dam, reservoirs, sewage pools, swimming pools, buildings, underground buildings, garbage dumps and mining projects. At the same time, because of the advantages of fast construction technology, good robustness, low cost and strong adaptability, Membrana HDPE liner and geotextile fabric have been widely promoted and applied in the reinforcement of complex broken open slope. The HDPE geomembrane liner has the following features.

  • Excellent chemical resistance.
  • Outstanding stress crack capacity.
  • Lowest permeability.
  • Excellent UV resistance.
  • Stable low temperature embrittlement resistance.
  • Complete width and thickness specifications.
  • Cost effective.
  • Meet or exceed all aspects of GRI GM13.

Construction Method of HDPE Membrane Liner

Before applying impermeable membrane liner, the slope surface should be leveled to prevent sharp outburst, and then the loose soil should be covered with membrana HDPE liner.
1) It should be extended from the bottom to the high position, not too tight, and 1.50% margin should be reserved for local sinking and stretching. Considering the actual situation of the project, the slope is laid from top to bottom.
2) The two adjacent longitudinal joints shall not be in a horizontal line, and shall be staggered by more than 1m.
3) The longitudinal joint shall be more than 1.50M away from the dam foot and bending foot, and shall be set on the plane.
4) Slope first and then bottom.
5) When the slope is laid, the HDPE geomembrane liner spreading direction should be basically parallel to the maximum slope line.
Slope laying: before laying the geomembrane liner on the slope, the laying area shall be inspected and measured. According to the measured size, the anti-seepage membrana HDPE liner with matching size in the warehouse shall be transported to the anchorage ditch platform. during laying, the convenient way of “pushing” from top to bottom shall be adopted according to the actual site conditions. In the sector area, it should be cut reasonably to make the upper and lower ends firmly anchored.
Site bottom laying: before laying the anti-seepage membrana HDPE liner, the laying area shall be inspected and measured, and the anti-seepage membrane liner matched with the size in the warehouse shall be transported to the corresponding position according to the measured size. During laying, the anti-seepage geomembrane liner shall be pushed manually in a certain direction.
Alignment and alignment:The paving of membrana HDPE liner, no matter the side slope or the bottom of the field, should be flat and straight to avoid wrinkles and ripples, so as to make the two geomembranes aligned and aligned. According to the design requirements, the lap width is generally about 10 cm.
Pressing: press the aligned and aligned BPM HDPE geomembrane with sand bags in time to prevent the wind from blowing and pulling. Laying in Anchorage ditch: at the top of anchorage ditch, a certain amount of impervious membrana HDPE liner shall be reserved according to the design requirements for local sinking and stretching.
Longitudinal joint: the uphill section is on the upper side and the downhill section is on the lower side, and enough lap length ≥ 15cm shall be reserved. The bentonite pad shall be laid in the area after passing the acceptance, and the manual “push paving” shall be carried out in a certain direction.
