Geomembrane

Geomembrane is a continuous flexible film made of polymer synthetic materials with excellent waterproof and isolation properties. It is widely used in landfills, water conservancy projects, agricultural irrigation, environmental protection facilities and other fields to prevent liquid leakage and gas diffusion, and to ensure the stability of engineering structures and environmental safety.Geomembranes are made of various materials such as High-Density Polyethylene (HDPE), Linear Low-Density Polyethylene (LLDPE), EPDM (Ethylene Propylene Diene Monomer), and Polyvinyl Chloride (PVC). Due to their ability to block fluids, they can help to prevent the dispersal of contaminants and may be used with soil liners or permeable geotextiles to create a composite lining system that provides added security.

Smooth Geomembrane

Smooth geomembranes manufactured from quality high density polyethylene resins(HDPE) that comply with the most rigorous requirements established for their use. They are smooth on both sides.

Textured Geomembrane

Textured geomembrane is a special type of geomembrane, whose surface has been specially treated with a rough texture, thereby increasing the friction with the soil or other materials and improving the stability of the project.

Composite Geomembrane

omposite geomembrane, also known as a composite anti-seepage membrane, waterproof geotextile fabric, or geotextile waterproofing membrane, is produced through thermal bonding of non-woven geotextile or woven geotextile, HDPE geomembrane, filler, and smear agent using oven far-infrared heating and guide roller calendering technology. It is categorized into four types: one cloth and one film, two cloths and one film, one cloth and two films, and multiple cloths and multiple films.

China Ldpe Geomembrane

It has become so intertwined with modern engineering that everything from environmental containment and waste management to aquaculture and mining finds some use. Geomembrane liners offer impermeable or near-impermeable barriers, inhibiting seepage and protecting the underlying soils and groundwater, adding much structural integrity to many projects. Many countries manufacture geomembranes; however, China has emerged as one of the biggest manufacturing hubs and offers many suppliers whose products cover a wide range of specifications.

China Geomembrane Roll Sheet

China Geomembrane Roll Sheet have a lower dense cell structure making them more flexible, easier to install, and less sensitive to stress cracking than HDPE geomembranes. Although, further comparison shows LLDPE has lower UV resistance, it’s still considered a great option for exposed applications.

Uses of Geomembrance

Frozen, pooling, flowing, wastewater, and standing liquids can be hazardous if not properly managed. Hence, geomembranes are used to prevent the loss of material.

The following are uses of geomembranes:

As liners for various waste conveyance canals
As waterproofing liners within tunnels and pipelines
As liners for the agriculture industry
As liners for potable or reserve water (for example, safe shutdown of nuclear facilities)
To contain and transport potable water and other liquids in the ocean
As liners for the agriculture industry
As fish pond liners
Beneath highways to prevent pollution from deicing salts
As liners for primary, secondary, or/and tertiary waste piles and solid-waste landfills
Adjacent and beneath highways to capture hazardous liquid spills
As liners for sewage sludge, radioactive or hazardous waste liquid
As linings for emergency spillways
To contain and transport liquids in trucks

Advantages of Geomembranes

Geomembrane barriers offer advantages over types of geosynthetics, which makes them the perfect choice for certain applications. The primary benefits of geomembranes include:

Cost-Effectiveness
The initial cost incurred in the purchase and installation of geomembranes are low compared to traditional concrete or clay liners. You also don’t have to worry about incurring high costs in their maintenance as they are highly durable.
Installation Efficiency
Geomembranes can be manufactured in small sections that can easily be assembled, allowing faster and more efficient installation.
Versatility
Geomembrane liners can be customized to meet your project needs. They can therefore be used for a wide array of applications.
Environment Friendly
The materials are highly impervious and resistant to hazardous substances hence contribute to the preservation of ecosystems and safeguard human health. Geomembranes offer effective containment of liquids and gases, preventing the contamination of soil and groundwater.
