Large fish pond liners are 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 liners are an excellent product for larger applications requiring UV and ozone resistance, chemical resistance or high quality installation. Large fish pond liners are 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 liners are important for the overall water containment, protection and health of your shrimp or fish farm ponds. HDPE geomembrane tank lining 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 lining material.

- Application – Shrimp Pond in Bangladesh
Issue
Our Bangladeshi customer left a message on social media Facebook telling us that he needed to purchase geomembrane pond liner for shrimp ponds and asked about the price of the geomembrane. In Bangladesh, shrimp farming is usually carried out in coastal areas because of the availability of 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
The customer shrimp farming in Bangladesh encountered the above problem. After communicating with our company, we recommended the customer to use a 0.5mm geomembrane pond liner. This method separates the pond water from the soil. Due to its durable and unbreakable characteristics, Large fish pond liners 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, geomembranes 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 geomembrane pond liner samples for testing. After receiving the samples for testing, the customer was very satisfied with the results. The customer purchased a 0.5mm geomembrane for use in a shrimp farming plant. Our team also provides customers with professional advice and guidance on the installation of geomembrane. During the installation process, we wholeheartedly considered the customer, gave the customer a detailed description of the specific steps of the installation, and reminded the customer to pay attention to three points:
(1) Before laying, the laying surface should be leveled and compacted, and sandbags or heavy objects should be prepared to prevent the laid HDPE geomembrane from being blown away by the wind.
(2) The slope of the breeding pond should not exceed 45°C, otherwise it is easy to collapse and it is not convenient for breeding.
(3) The anchoring ditch shall be dug into a U-shaped ditch or inverted trapezoidal ditch of 40cm-50cm, and then backfilled with soil.
Summary
- Large fish pond linershas high flexibility and can meet the anti-seepage requirements of different projects, with strong operability, convenient construction and low mechanical investment;
- The costof large fish pond linersis 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 large fish pond linersare 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.
