Geomembranes

Best Waterproofing Lining System

The use of membranes in civil and environmental applications is becoming more widespread as there develops a greater understanding of the effects of contaminated ground conditions on structures and the environment. Geomembranes provide an effective and efficient solution for waterproofing layer on various applications.

PRODUCT SUBCATEGORIES

G-Meb® CM Series

G-Meb® HDPE Series G-Meb® LLDPE Series

Composite Geomembranes

Provides the advantages of both geomembranes and geotextiles. And, the geotextile layer increases essential tensile strength and enhances tear and puncture resistance.

G-Meb® CM series are composite geomembrane, which is an impermeable material composed of geotextile and geomembrane liners. It is used for anti-seepage. The composite geomembrane liner has the advantages of geomembrane and geotextile at the same time. Geomembranes provide excellent seepage, leak, moisture, tear, and puncture resistance. The geotextile layer increases the tensile strength, and the composite geomembrane lining plays a great role in the landfill.

Applications

Chemical industry
Subway, tunnel
Garbage disposal

Features

High puncture resistance and high friction coefficient
Excellent anti-drainage performance

HDPE Geomembranes

The most widely used geomembrane liner for lining projects. HDPE geomembrane is extremely popular in lining applications requiring low permeability and high strength/density ratio.

G-Meb® HDPE series are made from the highest quality high density virgin polyethylene resins, conform to the stringent standards of GRI GM13. HDPE is known for its superior strength to density ratio. Although HDPE geomembrane is less flexible than LLDPE, it offers higher specific strength and can withstand somewhat higher temperatures.

Applications

Irrigation ponds, canals, ditches & reservoirs
Mining heap leach & slag tailing ponds
Landfill cells, covers & caps
Waste water treatment

Features

High tensile strength
Very low permeability
Low temperature brittleness

LLDPE Geomembranes

Due to its great flexibility and ductility, LLDPE gemembrane is more ideal for detailed and irregular surfaces such as tank lining and stormwater culvert wrapping.

G-Meb® LLDPE series are made from the highest quality low density virgin polyethylene resins, conform to the stringent standards of GRI GM17. It provides good mechanical strength, chemical resistance and UV resistance properties. LLDPE geomembrane is more elasticity and flexibility than HDPE geomembrane, and easy construction.

Applications

Irrigation ponds, canals, ditches & reservoirs
Mining heap leach & slag tailing ponds
Landfill cells, covers & caps
Waste water treatment

Features

Good flexibility and durability
High resistance to UV and chemical
High resistance to puncture, tear, cracking

Used in

01 Agriculture

Soil remediation

02 Hydraulic Engineering

Port, pond, reservoir, coastal beach, river, lake

03 Environmental Engineering

Landfill, tailing, waste water treatment

04 Energy Engineering

Power, oil, gas, coal mining

What is the difference between GCL and geomembrane?

G-Meb^® geomembranes are supplied as High Density Polyethylene (HDPE), Linear Low Density Polyethylene (LLDPE) and Low Density Polyethylene (LDPE) in large sheets (5-8m) with a thickness rang from 0.5mm to 3mm, black, green, or white color. GeoTrans Technology is able to arrange either on-site or factory fabrication of these products to suitable for applications.

G-Meb^® geomembranes manufactured using high quality polyethylene resins with smooth or textured surfaces providing impermeability in lining applications, most commonly used in lining of channels, small dams and other containment structures. G-Meb^®geomembranes are available with a conductive lower surface to allow for effective leak testing of installed geomembrane.

Frequently Asked Questions

1.Why use geotextile to install geomembrane?

Place a geotextile underlayment layer under the geomembrane, the geotextile can protect the geomembrane from damage by any sharp rocks. Geomembrane material is only a single layer of plastic film, which is prone to aging during use. Thus, laying a layer of geotextile on the surface can solve this problem.

2.What is the application and use of geomembrane?

Geomembrane is used in landfills, water reservoirs, ponds, tailing ponds, mine reclamation cover systems, wastewater treatment, secondary containment, shale oil and gas development, etc.

3.How is geomembrane welded?

Geomembrane can be Fusion Welding or Extrusion Welding to form a homogeneous bond between adjacent sheets of material.

4.What is the difference between GCL and geomembrane?

GCL and geomembrane are both excellent waterproofing materials used for lining applications. Although they have some similar anti-seepage properties. But they have obvious differences in composition, performance and installation.
