Ø Introduction, Materials and Characteristics of HDPE Geomembrane Pond Liner

HDPE (high-density polyethylene) geomembrane pond liner is made of polyethylene resin as raw material and formed by extrusion or blow molding. Its characteristics include: high impermeability and a compact molecular structure that blocks water leakage. Strong weather resistance, resistant to ultraviolet rays, acid and alkali corrosion, and microbial erosion; Excellent physical properties, high tensile strength, flexibility and bending resistance, adaptable to base deformation; Environmentally friendly and safe, the material is non-toxic and suitable for aquaculture, landscape and other water areas. It is commonly used in pond anti-seepage, sewage treatment and other projects. The thickness can be selected from 0.25 to 3mm. It is convenient to construct and has a service life of more than 50 years.

Ø Application fields

1.In aquaculture, its non-toxic, environmentally friendly and highly impermeable features not only ensure the healthy growth of fish and shrimp but also reduce water waste.

2. When the landscape water pool is in use, its high flexibility can adapt to irregular pool bodies, and its weather resistance ensures that it maintains its anti-seepage effect under sun exposure and rain, keeping the water feature beautiful.

3. It is used for agricultural irrigation, which can effectively reduce water seepage, improve irrigation efficiency, and has strong tensile resistance, not afraid of soil settlement and mechanical operations.

4. In sewage treatment tanks and industrial wastewater tanks, its excellent acid and alkali resistance and chemical corrosion resistance can resist the erosion of sewage and prevent the spread of pollution.

5. HDPE geomembrane is laid in landfill sites. With its puncture resistance and high impermeability, it can isolate leachate for a long time and safeguard the safety of the ecological environment.

Ø Factors affecting the anti-seepage effect of pond liners

I. Material Quality and Properties

Thickness and density

Insufficient thickness (such as less than 0.5mm) is prone to puncture damage, and low density (loose molecular structure) will increase the risk of leakage.

Purity of raw materials

Recycled materials or membrane materials with high impurity content have a high probability of molecular chain breakage, which is prone to form microscopic pores and reduce the anti-seepage performance.

2. Construction Techniques and Laying Quality

Base treatment

The bottom of the pool is not leveled and compacted, and there are sharp objects such as crushed stones and tree roots, which can easily puncture the membrane material. Uneven bases can cause local stress concentration in the membrane material, accelerating its damage.

Welding process

Improper control of temperature, pressure or speed in hot melt welding can lead to unstable weld seams, missed welds or false welds (such as weld lap width less than 10cm), creating leakage channels.

Joint treatment

Complex parts such as corners and edges that have not undergone reinforcement treatment (for instance, without using double welds or reinforcing patches) are prone to cracking due to stress concentration.

3. Environment and Usage Conditions

Geology and Subsidence

Uneven settlement of the foundation will cause excessive stretching of the membrane material, resulting in tearing of the weld points or fracture of the membrane body. Soil frost heaving and the creep of expansive soil can also damage the integrity of the membrane material.

Chemical and biological erosion

If the concentration of acid, alkali or salt in water or soil is too high (such as pH < 4 or pH > 10), long-term erosion will accelerate the aging of the membrane material. Microorganisms (such as certain bacteria) or plant roots penetrate the membrane, affecting the anti-seepage effect.

Ultraviolet Rays and Temperature

When exposed to ultraviolet rays for a long time in an open-air environment, the membrane material will undergo oxidation and degradation, and its flexibility will decline. Extreme temperatures (softening at high temperatures and embrittlement at low temperatures) can cause membrane materials to deform or crack.

4. Later Maintenance and Load

Man-made and mechanical injuries

During the aquaculture operation, the scraping of fishing nets and tools, or the subsequent mechanical compaction in the pond for dredging, may directly damage the membrane material.

Water pressure and Load

If the water level is too high, causing the membrane material to withstand water pressure exceeding the design value, or if heavy objects (such as stones) are piled up in the pool, it will cause local damage to the membrane material or failure of the weld points.

Ø Practical application cases

Case One: Roof pond of an agricultural breeding base

Project situation: A certain agricultural breeding base built a pond on the roof for fish breeding and adopted HDPE anti-seepage geotextile membrane as the anti-seepage layer at the bottom of the pond.

Application effect: HDPE geomembrane has excellent waterproof performance, effectively preventing water leakage, ensuring the stability of water level in the pond, and providing a good living environment for farmed fish. Meanwhile, evaporation loss is reduced, enabling the water in the pond to be retained for a longer time. Within the first year after the use of HDPE anti-seepage geomembrane, the survival rate of fish in this base increased by 15%, and the feed utilization rate also improved significantly.

Case Two: Aquaculture Farms in Sri Lanka

Project situation: In a certain aquaculture farm in Sri Lanka, to prevent dirt from seeping into the ponds, 0.6mm HDPE geomembrane linings were laid around the ponds. During construction, professional BPM welders installed the first batch of HDPE linings on site and taught local workers how to weld geomembrane linings.

Application effect: The anti-seepage performance and excellent long-term performance of HDPE geomembrane liner protect underground water resources from pollution. Its good tensile strength, impact resistance, tear resistance and high hydrostatic resistance effectively deal with the dirt in the pool. In addition, it has cut off the transmission route of the virus and played a certain disinfection role.

Case Three: Oxidation Pond in a Pig Farm

Project situation: For the anti-seepage project of the oxidation pond in a certain pig farm, 1.0mm geomembrane is used as the bottom liner and 1.5mm geomembrane as the covering layer. The foundation of the oxidation pond is solid with rammed earth treatment. The bottom is treated with high-density polyethylene geomembrane for anti-seepage, and the top is sealed with HDPE geomembrane. This project is designed and constructed as an energy and ecological biogas project, requiring sufficient farmland around to absorb the biogas slurry and residue after anaerobic fermentation.

Application effect: After the project was completed, the breeding farm initially established a three-dimensional ecological breeding farm with the "pig - biogas - vegetable (fruit)" model. HDPE geomembrane effectively prevents sewage leakage, avoiding pollution to the surrounding environment. At the same time, it turns waste into treasure, obtaining high-quality gas fuel and organic fertilizer, fully exerting the economic, energy, social, ecological and environmental benefits of this project.
