Farm pond liner, also known as HDPE geomembrane pond liner is made of high polyethylene raw materials, adding 2%-3% of carbon black, anti-oxidation, anti-aging and anti-ultraviolet components, and is made by first-class automatic production equipment and three-layer pressing process. HDPE geomembrane pond liner is an excellent product for larger applications requiring UV and ozone resistance, chemical resistance. HDPE geomembrane farm pond liner is a cost-effective option for exposed lining projects and are widely used in aquaculture, solid waste containment, mining, water containment applications and biogas digester projects.
Geomembrane pond liner is important for the overall water containment, protection and health of your shrimp or fish farm ponds. HDPE farm pond liner is the preferred lining material for shrimp or fish farm projects, that is, as the real foundation of your shrimp or fish farm, HDPE geomembrane lining is the best pond lining material.
Case Study
- Destination – Ecuador
- Product – 0.75mm Geomembrane
- Usage – Shrimp farming
Issue
In Ecuador, shrimp farming is usually carried out in coastal areas, as there are brackish or seawater supply ponds. Also, the land is swampy or sandy, and sometimes organic soils may appear. Such land is not suitable for growing crops or plantations, and the price is relatively cheap. Such land is also used to build ponds, and ponds built in soils that contain pyrite (potentially acid sulfate or active acid sulfate soils) can create low pH levels, which can cause problems for shrimp farming. Ponds built in sandy soil do not hold water well. Organic soils do not allow stable dikes and have a high oxygen demand. Due to the low-lying terrain, shrimp ponds built in these areas face difficulties in drainage and drying after harvest. The bottom of the pond is not completely dry, and after a few prawns have been raised, the bottom of the pond can deteriorate, which can stress the prawns and facilitate disease outbreaks.
Solution
A customer in Ecuador encountered the above problems in shrimp farming. After communicating with our company, we recommended the customer a 0.5mm or 0.75m HDPE geomembrane farm pond liner. This method separates the pond water from the soil. It is durable and not easy to break. HDPE geomembrane farm pond liner can not only effectively prevent weeds, sludge and other obstructive pollutants from entering the pond, but also reduce the bacteria in the pond environment, thereby reducing the use of antibiotics. In addition, HDPE geomembrane pond liner can also protect pond slopes from erosion and are extremely convenient for servicing and quick removal of sediment and waste. We provided customers with 0.5mm and 0.75m geomembrane pond liner samples for testing. After receiving the samples for testing, the customer was very satisfied with the results. In the end, the customer purchased a 0.75mm geomembrane for his shrimp farming pond. Our team also provided customers with professional advice and guidance on the installation of HDPE geomembrane farm pond liner.

The benefits of geomembrane pond liner for shrimp farming
- The farm pond liner system is stable. Compared to digging ponds directly, the use of HDPE geomembrane pond liner can make the slope more stable. It is beneficial to eliminate the threats brought by natural conditions such as wind, rain and waves to the fish pond, maintain the stability of the system during design, and prevent the loss of the cultured crops in the fish pond due to environmental damage. Moreover, the use of HDPE geomembrane liner can make the pond have a steeper slope and a deeper depth, which is equivalent to increasing the yield in disguised form. The stability of the system, of course, also reduces the maintenance of fish ponds and the cost of earthwork.
- Increase production. Because geomembrane pond liner is used, there will be no weeds, sludge and other things that affect the salvage speed at the bottom of the pond, so it can be fished more effectively. The fishing time will be greatly reduced, and the vitality and freshness of fish and shrimp will be greatly enhanced.
3.Disease hazards. After using geomembrane pond liner, the environmental adaptability of bacteria in fish ponds will be greatly reduced, thus maintaining the healthy growth of fish and shrimp. Due to the isolation of soil and water contact, the chemicals in the soil and germs will not spread to the pond, reducing the possibility of disease transmission. It can be said that the use of HDPE geomembrane reduces the cost of drugs for fish farming, as well as the risk of large-scale fish and shrimp deaths due to diseases.
4. Pond cleaning. After the geomembrane pond liner is installed, the cleaning of the pond will be easier. And it’s easier to install a clean drainage system inside the pond.
5. Improve the breeding cycle. Because HDPE geomembrane farm pond liner is used, it is easier to clean and fish, saving a lot of cost and time, which can speed up the cultivation of fish ponds and increase the output in disguise. At the same time, the choice of on-site venues is increased.
Technological characteristics of geomembrane pond liner used in shrimp ponds
- HDPE geomembrane pond liner has high flexibility and can meet the anti-seepage requirements of different projects, with strong operability, convenient construction and low mechanical investment;
- The cost is low and the economic benefit is high. According to the actual calculation, the use of this process will save about 50% to 30% of the cost of general projects with ordinary anti-seepage processes such as reinforced concrete self-waterproofing and clay waterproofing;
- The materials used in geomembrane pond liner are all environmentally friendly materials, and the principle of anti-seepage is ordinary physical changes, which do not produce any harmful substances;
- The anti-seepage coefficient is high, which can effectively overcome the uneven settlement of the base surface, and has a long service life under non-sunlight conditions, up to 30 to 50 years;
- The construction progress is fast and the efficiency is high.
Installation method of geomembrane farm pond liner
Base surface treatment
1) Flatness: ±5cm/m2, the base surface is flat and straight;
2) Compaction degree: more than 90%, the anti-seepage film can be laid on it after rolling;
3) Vertical and horizontal slope: the vertical and horizontal slope should be above 2%;
4) Base surface cleaning: There should be no sharp-edged objects within the vertical depth of 2.5cm.
Laying and cutting of HDPE geomembrane pond liner
1) Before laying the geomembrane pond liner, first check and measure the laying area, and transport the anti-seepage membrane with the matching size in the warehouse to the anchoring ditch platform according to the measured size. A convenient way to “push a shop”;
2) When laying geomembrane pond liner, it is necessary to strive for less welds, and on the premise of ensuring quality, try to save raw materials;
3) When laying, it should extend from the bottom to the high position, do not pull too tightly, and leave a margin of 1.50% for local sinking and stretching;
4) The longitudinal joints of two adjacent sheets should not be on a horizontal line, and should be staggered by more than 1m;
5) The longitudinal joint should be more than 1.50m away from the slope toe and the bent foot, and should be set on the plane;
6) Slope first and then the bottom of the field;
7) When laying the side slope, the film spreading direction should be basically parallel to the slope line;
8) After the geomembrane pond liner is laid, it is necessary to minimize walking on the membrane surface, moving tools, etc. Any objects that can cause harm to the geomembrane pond liner should not be placed on the membrane or carried on the membrane for walking. To avoid accidental damage to the geomembrane farm pond liner.
