HDPE Géomembrane liner is the widely used geosynthetic material for the anti-seepage lining projects in mines, ponds, dams, solid waste disposal sites and other industries projects because of its low permeability and strong corrosion resistance. BPM HDPE Géomembrane liner begins as raw polyethylene resin which is then processed into flexible HDPE liners. BPM HDPE géomembrane liner includes smooth geomembrane Liner, textured HDPE geomembrane and composite geomembrane liner which can be made into different colors including black, white and double color composite liners are also available. The smooth HDPE géomembrane has a higher UV resistance, suitable for outdoor environments. The textured geomembrane he textured geomembrane can be fabricated with single or double-sided surface to increase the friction coefficient to better suited to steep slopes and vertical engineering design needs, improve engineering stability.

Disposal of mine tailings is very important environmental concern for mining project. To control the release of tailing materials, a tailing dam or pond is created to contain the waste. As tailings commonly contain unvulcanized sulphide that can break down and release metals that can generate acidic conditions, they can represent a significant environmental hazard. Géomembrane liners are ideal geotechnical products used as the anti-seepage lining system for the tailing dams or ponds to protect the environment and prevent contamination of soils and groundwater tables.

BPM textured geomembrane process is a two-step forming method, that is, the roughening of the geomembrane is carried out by blowing and roughening on the basis of the blown film, the rough spots are not easily peeled off, and the various detection values of the original geomembrane are not changed. When the surface is sprayed and the rough film is laid, the géomembrane and the base surface will form a small gap layer, which can enhance the anti-bearing deformation force of the géomembrane. The textures geomembrane is generally used in projects where the surface of the slope geomembrane requires a large friction coefficient. Rough geomembrane can be divided into single rough surface and double rough surface. With the increasingly serious environmental problems, the requirements for environmental protection related projects are getting higher and higher, especially in waste sanitary landfill, tail mining and petroleum. In the chemical industry category, the  mine tailings contain heavy metal ions, toxic residual flotation reagents and acid waste water from the sulfur-containing minerals in the stripping waste rock. The impact on the environmental pollution and ecological damage of the mine and its surrounding areas will be long-lasting. The matte HDPE geomembrane can increase the friction coefficient and anti-slip function, which is more suitable for steep slope and vertical anti-seepage, and improve engineering stability. Here are several factors to consider when deciding which type of geomembrane to use in tailings:

  • Lower permeability
  • High tear and puncture resistance (depending on the type of terrain)
  • High chemical resistance
  • Long Duration of project
  • Good U.V exposure
Our South Africa customers had a bid of tailing project in DRC, they sent us the inquiry by email for many kinds of geomembrane products including 1.5mm hdpe textured geomembrane, 1.5mm hdpe smooth geomembrane and 5mm geocomposite with single 200gsm geotextile. We sent the price list, test report and loading details in the same day, BPM customers were satisfied with the our quick response. Several days later, they submitted the budget using our prices. About four days later, they updated the inquiry, they changed the HDPE double textured geomembrane into LLDPE double textured geomembrane, then we offered the new prices, after that the customer asked us to sent them the MQC cert and spec sheet which attached with the quotation to the engineer for approval. Then BPM customers asked us to sent them the samples for testing, our high quality géomembrane products passed their test, after confirming some details and immediately placed the order with us.
