Smooth Geomembrane

Smooth Geomembrane,  is a geosynthetic material with a flat and smooth appearance.

Material composition
Smooth Geomembrane is mainly made of high molecular polymers, such as high-density polyethylene (HDPE), through a specific production process. This material has excellent physical and chemical properties, such as high strength, corrosion resistance, and aging resistance.

Performance characteristics
Excellent waterproof performance: Smooth Geomembrane has extremely low permeability, which can effectively prevent the penetration of water and other liquids,ensuring the stability and safety of engineering structures.
Good chemical stability: The material can withstand the erosion of a variety of chemical substances, including acids, alkalis, salts, etc., and is suitable for various complex environments.
High strength and toughness: Smooth Geomembrane has high tensile strength and elongation at break, can withstand large stress and deformation, and is not easy to break.
Aging resistance: Due to the addition of auxiliary materials such as anti-aging agents, Smooth Geomembrane can maintain its stable performance for a long time and extend its service life.

Welding Techniques Used in Geomembrane Installation

Welding is necessary during Installation of geomembrane lining systems, which needs to be conducted by a professional welder. The two common welding techniques applied during geomembrane installation are:

1, Double hot metal wedge welding
2, Extrusion welding

The most reliable and suitable method is double hot metal wedge welding. It is important to observe the following during geomembrane welding:

• Make sure there is o any foreign material or debris on the surface you plan to weld.
• When you employ extrusion welding, ensure to remove oxidation through grinding and clean the debris due to grinding.
• Use double welds which are helpful in forming air channel between the welds to enable testing.
• Regular make some trials welds to test the efficiency of the welding method.



There is increasing application of geomembranes in several industries because of their versatility. Some of the sectors that register extensive use of geomembrane liners include:

1. Agricultural Sector – Farmers extensively use geomembrane liners in dam and pond lining since they offer reliable and cost-effective containment solutions. They also serve numerous roles in nurseries such as waterproofing and soil containment.

2. Mining Industry – Geomembrane in mining serve as lining solutions for tailing impoundments, heap leach pads, and evaporation pads. The geomembrane barriers prevent environmental pollution by hazardous chemicals from the mines.

3. Water Industry – There is immense geomembrane application in wastewater and drinking water treatment plants. The material prevents groundwater contamination when used to seal reservoirs, dams and canals.

Geomembrane liners are also valuable in avoiding potable water contamination by soil and other contaminants. It also hinders water loss via infiltration into the bordering soil.

Lining a canal or dam can reduce seepage, which enhances transportation and storage efficiency. Moreover, geomembrane linings also act as auxiliary containment for solar ponds, underground storage tanks, and brine solution.

4. Marine Industry – HDPE geomembranes find immense use in marine industry, especially in the building of jetty platforms or floating docks reinforced by pontoons. They give a protective barrier that elevates the longevity of the structure.

The HDPE geomembrane barrier guards the construction from destruction by environmental elements, marine life, and other pollutants inside the water. It equally provides the pontoon with extra buoyancy and avoids degeneration due to severe weather conditions, enhancing the general resilience of the pontoon.

5. Solid Waste Management Sector – Use of Geomembranes for landfills include employing them as landfill coverings or closures, cut-off walls, and base liners for leachate and waste containment. Landfills often incorporate composite liners comprising of geomembrane and geosynthetic clay liner.

6. Civil Construction – Civil engineering projects immensely use geomembrane liners, from integrated drainage systems, tunnels to roads and dams. They are essential in quickening installation times and controlling expenses whilst safeguarding existing structures. Furthermore, geomembranes are applied in geotechnics industry to curb flow issues, deformation, and failure load.
