How to Choose Right HDPE Impermeable Liner?

Over the past decade, HDPE impermeable Liner have played an important role in geotechnical projects. Our BPM brand geomembranes have been installed in various aquaculture projects around the world. With 20 years of geotechnical engineering experience, we provide customers with quality HDPE impermeable Liner products and professional geomembrane installation experience. Next, BPM Geosynthetics will discuss HDPE impermeable Liner as the best choice for aquaculture projects from the following aspects.

When building a pond, deciding on the proper cloth is quintessential to make sure its toughness and functionality. High density polyethylene HDPE sheet is a famous desire for lining ponds due to their durability, flexibility, and resistance to a range of environmental factors. However, selecting the terrific HDPE impermeable Liner for your geosynthetics mission requires cautious consideration of various key elements to make certain its overall performance and longevity.

1. What is HDPE Impermeable Liner?

As we all know, HDPE impermeable Liner is the most commonly used waterproof material. It uses polyethylene virgin resin as raw material, adds carbon black, anti-aging agent and anti-ultraviolet absorber, etc. It is produced by three-layer co-extrusion blow molding process or calendering process technology using hdpe sheet equipment. HDPE impermeable Liner is often used in aquaculture projects, garden projects, salt ponds and mining projects and tailings low-sinking and anti-seepage projects.

2. How to Choose the Right HDPE Impermeable Liner for Your Pond?

2.1 HDPE Impermeable Liner Material Cost

In the geotechnical material market, there are many materials for HDPE impermeable Liner, such as HDPE materials, LDPE materials, LLdpe materials, PVC materials, EPDM materials and so on.According to BPM Geosynthetics export experience, HDPE material is often used in pond.

2.1.1 HDPE Impermeable Liner Material cost

HDPE impermeable Liners are known for their chemical resistance and durability, making them ideal for pond liners. HDPE impermeable Liner are resistant to many different chemical elements and are the most widely used pond liners in the world. HDPE sheet geomembranes are not as flexible as LLDPE material, but they are mechanically stronger and HDPE can withstand higher temperatures. Its excellent chemical resistance and UV resistance make it a very cost-effective product.HDPE material has the lowest price among all materials.

2.1.2 LDPE,LLDPE lmpermeable Liner material

Compared with HDPE, LDPE and LLDPE have greater flexibility and are suitable for applications that require better conformity to complex shapes. LLDPE liner is highly flexible and resistant to low temperatures and UV rays. The product is high quality, affordable, long-lasting, and durable. If the pond has complex and varied shapes and requires good flexibility, then customers can choose LLDPE because LLDPE material is more flexible than HDPE, and at the same time, their material costs are almost the same.

2.1.3 PVC material, EPDM material

PVC is a highly flexible thermoplastic waterproof sheet made from a mixture of vinyl compounds, plasticizers and stabilizers. PVC sheet have excellent puncture, abrasion and tear resistance, preventing pollutants from entering groundwater, thereby protecting drinking water sources. Its wide chemical compatibility also makes it the best choice for buried sheet lining applications. Therefore, PVC liner is more commonly used in  agricultural applications due to its flexibility and easy installation. EPDM liner is highly flexible and resistant to UV exposure, making it ideal for exposed applications such as ponds and canals. Both products cost more than HDPE.

To sum up, in terms of chemical properties and price, HDPE impermeable Liner is the best choice in pond projects.

3. Which Factors Matter Most When Selecting an HDPE Impermeable Liner?

3.1 HDPE Impermeable Liner thickness

The thickness of the HDPE impermeable Liner is a key component to consider. Thicker HDPE sheet have higher puncture resistance and durability, offering higher safety from sharp objects and conceivable damage. Choose a thickness that fits the measurement and depth of your pond to make sure ample protection.

HDPE impermeable liners are available in a variety of thicknesses to suit different application needs. The most commonly used thicknesses include:0.2mm, 0.5mm, 0.75mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm

- General Aquaculture Ponds: For fish and shrimp farming or small irrigation ponds, a thickness of 0.75mm to 1.0mm is generally sufficient. This range provides adequate flexibility, puncture resistance, and long-term waterproofing performance.

- Industrial or Tailing Pond: In applications such as mining tailing storage, waste containment, or chemical ponds, a thickness of 1.5mm to 2.0mm is recommended to ensure enhanced durability, chemical resistance, and structural stability under higher environmental stress.

All thickness measurements should comply with the ASTM D5199 standard, which specifies the test method for measuring the nominal thickness of geomembranes. This ensures consistent product quality and reliable performance across projects.

3.2 HDPE Impermeable Liner - UV Resistant Performance

Ponds are uncovered to sunlight, which can motive some substances to degrade over time. Choose HDPE impermeable Liner that are UV stabilized to make sure they can face up to extended daylight publicity barring deterioration. UV resistant HDPE impermeable Liner will preserve their integrity and overall performance over a lengthy duration of time.
