What is Geomembrane?
A geomembrane is very low permeability synthetic membrane liner or barrier used with any
geotechnical engineering related material so as to control fluid (liquid or gas) migration in a
human-made project structure or system.
Main Features of HDPE Geomembrane:
1.Excellent anti-seepage performance geomembrane has extremely low permeability and can effectively prevent the penetration of water and other liquids, thereby preventing seepage.
2.Good durability geomembrane has good anti-aging properties and chemical stability, and can be used for a long time in various harsh environments.
3.Convenient construction geomembrane has high flexibility and ductility, is easy to lay and connect, and construction is convenient and fast.
4.Economical and affordable geomembrane has a relatively low cost, long service life, low maintenance costs, and high cost performance.

Production Process & Package
DXD is dedicated to an objective of continuous commitment to quality. This dedication begins with the manufacture of the geosynthetic material and ends only when our customer has accepted our products. The employees of DXD, therefore, endorse and require a policy of Total Quality. This policy is based on the principle that quality is the fundamental responsibility of every department and is carried out by each person in that department.
Programs and procedures designed to implement this quality principle are developed by the Quality Control Department and are utilized by every employee of the Company. DXD Manufacturing processes are ISO 9001:2015 registered.
..................................
Water Resource Management:
Geomembranes are employed in water resource management for reservoirs, ponds, and irrigation canals. They serve as liners to prevent seepage and retain water, ensuring efficient water storage and distribution.
Mining Industry:
Geomembranes play a crucial role in the mining industry for containment of tailings, heap leach pads, and other mining waste. They help in preventing environmental contamination by isolating potentially harmful substances from surrounding soil and water.
Agriculture:
In agriculture, geomembranes are used for various purposes such as lining agricultural ponds, irrigation reservoirs, and manure storage facilities. They help in water conservation, nutrient management, and preventing groundwater pollution.
Civil Engineering and Construction:
Geomembranes find applications in civil engineering projects such as tunnel waterproofing, canal lining, and slope stabilization. They provide protection against water infiltration, soil erosion, and chemical corrosion, enhancing the durability of structures.
Aquaculture:
Geomembranes are utilized in aquaculture for constructing ponds, tanks, and raceways. They create impermeable barriers to retain water and facilitate efficient management of aquaculture operations, including fish farming and shrimp production.
