1. What is geomembrane ？
1.1 Definition
Geomembrane is a high-molecular composite material made of polyethylene (PE) through extrusion and stretching. It features high temperature resistance, water impermeability, chemical corrosion resistance, and aging resistance, and is widely used in water conservancy, transportation, agriculture, and environmental fields.
1.2 Classification
Based on different uses and applications, geomembranes can be classified into various types, including HDPE geomembrane, LDPE geomembrane, LLDPE geomembrane, and PVC geomembrane. HDPE geomembrane is currently the most widely used type, characterized by its toughness, corrosion resistance, and resistance to high and low temperatures. It is widely used in landfills, sewage treatment plants, water conservancy projects, and hydrological construction.
1.3 Applications
Water Conservancy Engineering: Applied to seepage prevention, isolation, and protection projects such as reservoirs, dikes, river channels, and tunnels;
Environmental Protection: Applied to landfills, hazardous waste, temporary urban waste disposal sites, and wastewater treatment;
Transportation Construction: Applied to pavement protection for highways, streets, and railways, as well as waterproofing for tunnels and underground projects;
Agricultural Construction: Applied to water conservancy, irrigation, seepage prevention, and water storage;
Building Engineering: Applied to foundation treatment, building material protection, and thermal insulation projects.
2.Geomembrane Big Demanding the Thailand
Thailand has a substantial demand for geomembranes, and this demand is expected to continue its steady growth trend in the coming years.
This is primarily due to Thailand’s ongoing investment in infrastructure development, water resource management, and agricultural modernization. The following is an analysis of several key demand areas:
2.1 Water Resource Management (Largest Source of Demand)
Reservoirs and Irrigation Ponds: Thailand has a developed agricultural sector, but seasonal rainfall is uneven. To ensure water supply during the dry season, the government and individuals are heavily investing in the construction and repair of reservoirs, irrigation ponds, and water storage tanks. Geomembranes, with their excellent impermeability, are the preferred material for lining these facilities, effectively reducing water loss through seepage.
Canal and Ditch Lining: To improve water conveyance efficiency and prevent irrigation water from seeping into the ground during transport, geomembranes are widely used for lining canals and ditches.
Sewage Treatment and Oxidation Ponds: With increasing environmental awareness, wastewater treatment plants and oxidation ponds (stabilization ponds) in industrial areas and communities require reliable impermeable layers to prevent sewage leakage and contamination of groundwater and soil. Geomembranes are a core material in this context.
2.2 Environmental Engineering
Landfills: This is a classic application of geomembranes. Thailand is promoting more modern waste management methods, and newly built sanitary landfills must use HDPE geomembranes as impermeable lining systems to isolate leachate and protect the environment.
Industrial Waste Disposal Sites: Waste and tailings from mining, power generation, and other industries require safe disposal; geomembranes are used to prevent the leakage of hazardous substances.
2.3 Aquaculture
Thailand is a major global aquaculture producer (such as shrimp and fish). Geomembrane-lined aquaculture ponds offer advantages such as easy cleaning, prevention of pathogen growth, water level control, and improved survival rates, making them popular with large-scale and high-standard aquaculture farms and gradually replacing traditional earthen ponds.
2.4 Infrastructure Construction
Roads and Railways: When constructing roads on soft soil foundations, geomembranes are often combined with geotextiles as isolation and reinforcement layers to prevent the roadbed material from mixing with the soft soil and improve roadbed stability.
Tunnels and Underground Engineering: Used for waterproofing and moisture protection.
