0.2 - 2mm Dam Reservoir Mining Fish Farm Pond Liner HDPE Geomembrane

High Density Polyethylene (HDPE) geomembrane liners are used in a wide range of containment applications. Available in smooth, textured, white, conductive and high temperature variations, this material provides excellent durability and chemical resistance properties and is reliable in exposed applications, offering great ultraviolet protection and ageing resistance from the intense stresses of weather.

HDPE geomembranes are available in a variety of surface finishes including textured, smooth and conductive. Textured finishes provide higher friction angles to prevent slippage of adjacent materials when lining steep slopes while smooth geomembranes are the preferred products for lining projects requiring low permeability. Due to the relative stiffness of HDPE, field seaming by Nilex's trained geomembrane installers is generally required.

What is geomembrane Categories?

As defined, a geomembrane is an essentially impermeable membrane used with foundation, soil, rock earth or any other geotechnical engineering-related material as an integral part of a man-made project, structure or system. There are various types of geomembranes including polyvinyl chloride (PVC), chlorinated polyethylene (CPE), chlorosulphonated polyethylene (CSPE), ethylene propylene rubber (EPDM), polypropylene (PP), linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), etc. It is important to note the so-called HDPE geomembrane that is the most common type of geomembrane used in facilities.
Following is the brief introduction of the three main types of geomembrane products, smooth geomembrane, textured HDPE geomembrane and composite geomembrane liner.

1. Smooth geomembrane.

This kind of geomembrane is typically made of finest quality high density polyethylene (HDPE) with specially formulated, virgin polyethylene resin, combined with specified quantity carbon black, antioxidant, anti-aging agent and UV resistance components. It can be used for canal, aquaculture, irrigation ponds and remediation liners, other liner applications include landfills, waste water treatment lagoons, oil and gas exploration, power plants, etc al. BPM smooth geomembrane HDPE linere is engineered and fabricated by the state of the art automatic geomembrane production lines and advanced three layered pressing technology in accordance with GRI GM13 standard.

2. Textured HDPE geomembrane.

In general, HPDE geomembranes consist of 96–97.5% of polyethylene resin, 2–3% of carbon black and 0.5–1.0% of other additives such as antioxidants and stabilizers. Polyethylene is a high molecular polymer, non-toxic, odorless and odorless white particles, its melting point is about 110 °C -130 °C, its relative density 0.918-0.965. HDPE geomembrane is specially designed and fabricated for many applications due to its advanced stabilization, excellent interface friction coefficient and inherent flexibility. HASSAN HDPE geomembranes have been widely in backfilled liner, retaining backfill on steep side, heap leach pads, landfill protection applications such as dam, reservoirs, sewage pools, swimming pools, buildings, underground buildings, garbage dumps and mining projects. HDPE geomembrane designed and fabricated with either single-sided or double-sided textured surface is called Textured HDPE Geomembrane. Textured HDPE Geomembrane has a rough surface which can highly improve the friction coefficient which fits more suitable for steep slope and vertical engineering design work which maximize the effective volume of geomembrane, they are also proceed with smooth edges to allow for high quality thermal fusion welding between adjacent sheets.

3. Composite geomembrane liner.

Composite geomembrane liner is made by heat-bonding nonwoven or woven geotextile to HDPE geomembrane by calendaring processing technology. HASSAN composite geomembrane liner provides the advantages of both geomembrane and geotextile, which is made of specially formulated HDPE resin combined with specified quantity carbon black, anti-aging agent and UV resistance components. The geotextile layer increases essential tensile strength and the geomembranes provides excellent impermeable, leak and moisture proof. Compared with traditional concrete, asphalt and compacted clay, composite geomembrane liner has proven to be far more cost effective, environmentally safe, excellent durable, chemically resistant, fast deployment and easy transportation. Composite geomembraneliner is mainly used in water dams, artificial lakes, airports, construction, environmental protection, water containment and other projects.
The selection of a geomembrane liner depends upon the application in which it will be used. High-density polyethylene (HDPE) geomembranes have been used exclusively in landfill applications, especially for bottom liners, because of their relatively high resistance to aggressive leachate components.

What is geomembrane functions?

Geomembrane has the function of seperation, drainage, reinforcement and protection, etc.

•  Separation. Separate building material (soil and sand, soil and concrete, etc) with different physical properties, such as particle size, distribution, consistency and density, etc.
•  Drainage. It can form a drainage channel inside the soil and remove excess liquid or gas from the soil structure.
•  Reinforcement. The HDPE liner can be used to enhance the tensile strength and resistance to deformation ability of soil, meanwhile, to improve the stability of the building structure and soil quality.
•  Protection. It can effectively diffuse, transfer or decompose the concentrated stress to prevent the soil from being destroyed by external forces, when the water scouring the soil.

What is geomembrane applications?

The geomembrane produced by HASSAN is typically made from high grade polyethylene raw material, adding carbon black, antioxidant, anti-aging and UV resistance component. Geomembrane has the function of seperation, drainage, reinforcement and protection, etc. So geomembrane and related products have many applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering.
Although quite subjective, one can view current geomembrane application areas in three categories: transportation related, environmental related, and geotechnical related. Each category has a number of specific applications.

Applications:

Channels
Small dams
Containment areas
Landfill liner & caps
Golf course Ponds
Pond and lake liners
Irrigation reservoirs
Waste water treatment
Mining tailing
Canal lining

With an ever increasing worldwide population growth, water supplies will become more scarcely and require storage reservoir and surface impoundment liners. Similarly, canal liners for the transportation of t h is water to areas of primary use is an important applications. Recent concerns of potable water reservoir pollution from the atmosphere has ushered in the concept of floating geomembrane covers. With industrialization on a worldwide basis comes the necessity of canal liners to transport chemicals and waste waters. The application here is among the most demanding of all geomembrane applications. Therefore, the development of geomembrane liner is very fast, and has become the main component of geomembrane liner.
