Impermeable geomembrane general characteristics including physical properties, mechanical properties, chemical properties, thermal properties and durability and so on. Impermeable geomembrane in engineering applications, attach more importance to its waterproof (impermeable) performance, resistance to deformation and durability. A lot of engineering practice proved impermeable geomembrane has good permeability; elastic strain capacity, able to withstand the different construction conditions and work stress; good aging capacity in underwater soil geomembrane Durability is particularly prominent. The most widely used or impermeable geomembrane. 
 Pairs of smooth HDPE impermeable geomembrane, a glossy high-quality high-density polyethylene (HDPE) produced by a special formula of virgin resin impermeable geomembrane. The resin is designed specifically for flexible geomembrane of. It contains approximately 97.5% polyethylene, 2.5% carbon black and trace amounts of antioxidants and heat stabilizers, no other additives, fillers and expanders. Smooth impermeable geomembrane with excellent chemical resistance, mechanical properties, resistance to environmental stress cracking resistance, dimensional stability and heat aging properties, but also has excellent resistance to ultraviolet radiation performance and suitable for outdoor environment. 
 A safe non-polluting impermeable geomembrane with excellent resistance to chemical properties: high temperature resistance, resistance to asphalt, oil and tar, acid, alkali, salt, and other media of more than 80 kinds of acid and alkali chemical corrosion 
 Outstanding environmental stress cracking resistance: elongation rate, which can effectively overcome the uneven settlement of the base surface 
 3, excellent UV resistance: excellent anti-aging, anti-UV, resistance to degradation, can be exposed using the material life of 50-70 years; stable low-temperature performance of vertical oriented: less than n 77 ℃ ~ - 90 ° C the brittle point. 
 4, anti-plant roots: the impermeable geomembrane with excellent puncture resistance capacity, is resistant to most plant roots 
 5, environmentally friendly non-toxic: nontoxic materials, impermeable principle of the common physical changes, does not produce any harmful substances. 
 6, construction quality assurance system: a variety of specifications to a variety of laying the forms to meet the seepage control requirements of different projects, the use of hot melt welding, weld strength. 
 hdpe impermeable membrane laying Note: 
 Impermeable geomembrane, the cell body to clean up the leveling. The laying of the surface of the vertical depth of 25mm shall not be sharp debris: such as rubble, gravel, concrete particles, steel head, metal or other debris, etc. enough to pierce the debris of the impermeable geomembrane. 
 Impermeable geomembrane for flexible materials, according to the cell body of any structure, to do any modeling package lining. All corner, rectangular section, shall be made into fillets or chamfers to avoid damage to the impermeable geomembrane. 
 Finished laying, should be followed by welding pipe node, Yang angle, corner tricky place, with the hot air machine and extrusion welder welding. 
 Pressure side anchoring: with expansion bolts, the pressure, the pressure side anchor. Pressure finished edge, and then the impermeable geomembrane anchoring parts, sealing and welding, so that the formation of the impermeable anti-corrosion lining. 
 Case design phase, you can use embedded forms of anchoring. Anchor embedded in the concrete wall, laying to the specified location, directly welded to the anchor on to form a complete impermeable body. Can be applied to the pressure side of the brick wall, impermeable geomembrane laying to the required position, back side at the walls, brickwork fixed.
