How thick should a HDPE pond liner be?

The main function of high-density polyethylene pond liners is to avoid direct contact with soil and avoid water pollution. High-density polyethylene pond liners prevent waste from accumulating in the soil and prevent harmful chemicals such as ammonia, hydrogen sulfide, acids, iron, and other harmful compounds from entering the pond, thus reducing the risk of disease and Protecting and promoting fish growth.

High-density polyethylene pond liner is a flexible waterproof barrier material produced from high-density polyethylene resin and does not contain any preservatives. The high-density polyethylene pond liner itself has a high anti-seepage coefficient (1×10-17 cm/s), and its use environment temperature is high temperature 110°C and low temperature -70°C. It has a strong anti-aging performance and can be used for a long time. While maintaining the original performance, it can operate in a variety of harsh geological and climatic conditions.

How thick is a high-density polyethylene pond liner generally chosen?

1. Fish pond depth: The thickness of the high-density polyethylene pond liner is generally based on the depth of the fish pond. The depth of the fish pond is an important factor because it involves the ability of the high-density polyethylene pond liner to withstand water pressure. Deep fish ponds may require a thicker geomembrane to ensure waterproofing. Usually, if it is shallower, choose 0.50mm-0.75mm thick, and if it is deeper, choose 0.75mm-1.5mm thick.

2. Fish pond service life: It also depends on the service life of the fish pond. If it is used for 3-5 years, choose a 0.50mm-0.75mm thick high-density polyethylene pond lining. If it is used for 5-10 years, choose a 0.75 mm-1.5 mm thick high-density polyethylene pond lining. pad. If you expect your fish pond and geomembrane to have a longer life, choosing a thicker geomembrane may be a wise choice.

3. Fish pond uses: Different fish pond uses may require geomembranes of different thicknesses. In the case of only fish, you can choose 0.50 mm-0.75 mm thickness. If it is used for shrimp and crab farming, choose a thickness of 0.75 mm-1.5 mm. A thicker geomembrane is needed to deal with potential damage risks.

4. Soil conditions: Different types of soil have different effects on the penetration and durability of geomembranes. If the soil is highly penetrating or contains sharp objects, a thicker geomembrane may be required.

Specifications of High-Density Polyethylene Pond Liner

1. The width of a high-density polyethylene pond liner is 3-10 meters, and the most common one is 5.8-8 meters.

2. The thickness of high-density polyethylene pond liner is 0.3-2.0mm, and the length can be customized.

High-Density Polyethylene Pond Liner Features:

High-density polyethylene pond liner is anti-aging, anti-ultraviolet, very good in tear resistance, puncture resistance, large friction coefficient, low brittleness, small thermal deformation, good chemical stability, adaptable to a wide range of environmental temperatures, and resistant to high temperatures Low temperature, resistant to asphalt, oil and tar, acid, alkali, salt and other chemical solutions, very good anti-seepage effect, short construction period, low cost, resistant to plant roots, chemical corrosion resistance, good anti-seepage effect.

High-density polyethylene pond liner is the geomembrane liner of choice for most applications because of its unique properties such as chemical resistance, puncture resistance, flexibility, and more.
