HDPE landfill liners are the synthetic membrane barrier with extremely low permeability that can be used in conjunction with any geotechnical material to regulate fluid (or gas) migration in a man-made project, structure or system. HDPE landfill liners can be impregnated with bitumen, elastomeric or polymer sprays, or as multi-layer bituminous geocomposites. By far the most common is the continuous polymer HDPE geomembrane liner.
Case Study
- Destination – Thailand
- Product -1.5mm HDPE Landfill Liners
- Application – Solid Waste Landfill Project
Issue
Effective waste management in Thailand requires integrated solutions combining source separation, recycling initiatives, and engineered landfills. Communities benefit when informal recycling sectors collaborate with formal systems to divert waste from disposal sites. However, growing urbanization exposes critical gaps – uncontrolled dumping contaminates groundwater through toxic leachate while degrading soil and air quality.
The government’s new waste management initiative prioritizes:
-
Source separation to boost recycling rates
-
Sanitary landfills with geomembrane liners to block pollution
-
Formal-informal sector integration to maximize resource recovery
These measures combat environmental and health risks while addressing Thailand’s waste volume challenges. Geosynthetic containment systems prove essential for safe, long-term waste disposal.
Solution
For Thailand’s waste management project, BPM specified a robust containment system combining 1.5mm HDPE geomembrane with 300g filament geotextile. This dual-layer solution delivers:
-
Superior containment – The HDPE liner’s ultra-low permeability (≤1×10⁻¹³ m/s) prevents hazardous leachate migration
-
Multi-functional protection – Geotextile provides filtration, drainage, and puncture protection
-
Long-term performance – UV-resistant materials maintain integrity for 30+ years
The system addresses critical landfill needs:
-
Blocks groundwater contamination
-
Withstands chemical/biological degradation
-
Reduces maintenance costs
Engineers worldwide prefer this combination for its proven balance of environmental safety and cost-efficiency.

2.Organized control of odor emissions from landfills and discharge and collection of combustible gas from the upper part of landfills to achieve the purpose of pollution control and comprehensive utilization;
3.Inhibit the reproduction and transmission of pathogenic bacteria and their disseminator, mosquitoes and flies;
4.Prevent surface runoff from being polluted, avoid spreading garbage and direct contact with humans and animals;
5.Prevent soil erosion;
6.Promote the stability of garbage dumps as soon as possible;
7. Provide a surface that can be beautified, provide soil for vegetation growth, promote the reuse of landfills, etc.
Installation of HDPE Landfill Liners for Solid Waste Containment Project
1. The base surface of the geomembrane construction requires
That the surface of the installation base should be tamped and leveled, and sharp objects such as tree roots, stones, glass and iron nails should be removed; the internal and external corners of the base should be trimmed and rounded, and the fillet radius ≥50cm, and the surface of the welding seam should be cleaned. Clean; the construction of geomembrane can be carried out after the acceptance and signature of the civil engineering and supervision construction party;
2. The climate requirements for geomembrane construction
Generally be above 5℃. The geomembrane should be tight at low temperatures, and the geomembrane should be relaxed at high temperatures. Geomembrane installation and construction should be appropriately pre-released to an extension of 2% to 5% according to the specific site conditions and the prevailing climatic conditions; the wind is below; when the temperature is too low, the construction should not generally be carried out in strong winds or rain and snow above level 4; in windy weather, When the wind affects the construction of the geomembrane, the geomembrane to be welded should be pressed firmly with big rocks or sand bags;
3. The laying of geomembrane.
The laying of geomembrane is the arrangement direction of the seam in the entire anti-seepage system parallel to the slope toe line, that is, it is arranged along the slope direction. When laying geomembrane, we should try to minimize the number of welds. Under the premise of ensuring quality, we should save raw materials as much as possible, and it is also easy to ensure quality. Usually in corners and deformed areas, the length of the joint should be as short as possible. In addition to requirements, on slopes with a slope greater than 1:6, within 1.5m from the top slope or stress concentration area, try not to install welds;
4. During the laying of the geomembrane, artificial wrinkles should be avoided.
When the temperature is low, it should be stretched and flattened as much as possible. After the geomembrane is set up, it is necessary to minimize walking and moving tools on the surface of the geomembrane. Anything that can cause harm to the geomembrane should not be placed on the geomembrane or carried on the film to avoid accidents to the geomembrane. damage;
5. Tthe more critical process
the appearance quality of the geomembrane is unpacked and inspected before the film is laid, and the discovered mechanical damages, production wounds, holes, breakages and other defects are recorded and repaired. Before cutting the geomembrane, measure its relevant size, and then cut it according to the actual cutting. The lap width of the seam between the membrane and the membrane is 10cm~15cm, so that the direction of the seam arrangement is parallel to the slope foot line, that is, along Arrangement in slope direction;
6. Addition
In order to better guarantee the effect of the geomembrane construction, it is also necessary to pay attention to when laying the geomembrane, do not pull it too tightly, and leave a certain amount of expansion and contraction. At the same time, it should be noted that the protective layer must be well covered to avoid some heavy objects from damaging the geomembrane.
