Pond liner fabric is the impermeable geomembrane liner which is defined as a reinforced bituminous sheet for such lining applications as reservoirs, retention basins, hazardous and nonhazardous surface impoundments. The pond liner fabric is used extensively in tank lining and transportation applications, environmental applications and geotechnical related applications in substitution or in addition to compacted clay, bentonite, concrete, steel and bituminous materials. BPM pond liner fabric is made of finest quality high density polyethylene (HDPE) with specially formulated, virgin polyethylene resin, combined with specified quantity carbon black, antioxidant, anti-aging agent and UV resistance components. Welding or adhesive techniques are used to bond the geomembrane sheet with the inside wall of oil tank together. Pond lining sheet has proven to be far more cost effective, environmentally safe, excellent durable, chemically resistant, fast deployment and easy transportation.

The Essential Characteristics of Quality Pond Liner Fabric

When selecting pond liner fabric, understanding its key characteristics ensures optimal performance and longevity. High-quality liners combine material science with engineering precision to create reliable water containment solutions.

1. Impermeability & Water Retention

Premium pond liners completely prevent water seepage, maintaining consistent water levels. Their ultra-low permeability (typically <1×10-12 cm/s) ensures no liquid escapes into surrounding soil. This characteristic proves vital for irrigation ponds, aquaculture systems, and decorative water features.

2. UV & Weather Resistance

Durable liners incorporate carbon black and stabilizers to withstand prolonged sun exposure. They resist cracking in freezing temperatures and remain flexible in heat. This UV protection allows exposed installations without soil cover, reducing project costs.

3. Puncture & Tear Strength

Reinforced fabrics withstand sharp rocks, roots, and wildlife activity. High tensile strength (25+ MPa) and puncture resistance (500+ N) prevent damage during installation and use. Textured surfaces add extra protection against abrasion.

4. Chemical & Environmental Safety

Fish-safe formulations contain no toxic plasticizers or heavy metals. The inert material won’t leach harmful substances, making it ideal for aquaculture and drinking water storage. It also resists algae growth and microbial degradation.

5. Installation Advantages

Lightweight yet rugged liners adapt to complex contours easily. Thermal welding creates seamless, leak-proof joints. Available in wide panels (up to 9m) to minimize seams, they install 50% faster than concrete alternatives.

Why These Features Matter

  • Durability: 20-30 year lifespan reduces replacement costs

  • Versatility: Suitable for ponds, landfills, and industrial uses

  • Eco-Protection: Safeguards groundwater from contamination

Pond Liner Fabric for Gold Tailing in Guizhou
Pond Liner Fabric for Gold Tailing

Case Study Of Pond Liner Fabric

The large amount of gold tailings will not only occupy a large amount of land and farmland resources but also be stored in the open air, harmful components with harm the atmosphere, soil surface or groundwater due to long-term exposure to the sun, wind or rain the gold tailings lime can decompose. The medium will destroy the ecological environment and affect the physical and mental health of local resident, the dust generated by it will deteriorate the air and environment in the surrounding areas.

Our customer in Guizhou apply pond liner fabric for the gold tailing project on September,2018. After make an on-the-spot investigation for geomembrane manufacturers, they confirmed the quality of our pond liner fabric. We recommend two specifications to our Guizhou customers. One is for ground laying, the other is for steep slope laying. Finally, we reached the agreement on 40,000 square meters of pond liner fabric products for tailing project .We finally determine the specifications and quantity of the HDPE geomembrane products, and suggested BPM 1mm and 1.5mm pond liner fabric for gold tailing project.

Specifications of Pond Liner Fabric for Gold Tailing in Guizhou

• Total quantity – 350,000m2
• Each roll size – 6m×100m, 3m×50m
• Specification–250g/m2, 300g/m2, 500g/m2

How to Choose the Right Pond Liner Fabric

Selecting the ideal pond liner fabric is crucial for durability, water retention, and environmental safety. Below are key factors to consider for different applications, including aquaculture, landscaping, and industrial use.

1. Determine the Right Material

Pond liners come in various materials, each with distinct advantages:

  • HDPE (High-Density Polyethylene): Best for large ponds, landfills, and industrial use due to its strength and chemical resistance.

  • LLDPE (Linear Low-Density Polyethylene): More flexible than HDPE, ideal for irregularly shaped decorative ponds.

  • EPDM (Ethylene Propylene Diene Monomer): Highly flexible and fish-safe, perfect for koi ponds and aquaculture.

  • PVC (Polyvinyl Chloride): Budget-friendly but less durable; suitable for temporary or small water features.

Recommendation: For long-term use, HDPE or EPDM are the most reliable choices.

2. Check Thickness & Durability

  • 0.5mm–1.0mm (20–40 mil): Suitable for small garden ponds with minimal stress.

  • 1.0mm–1.5mm (40–60 mil): Ideal for medium-sized ponds and moderate fish loads.

  • 1.5mm–2.0mm (60–80 mil): Required for large ponds, commercial aquaculture, and harsh environments.

Why It Matters: Thicker liners resist punctures, UV damage, and last decades.

3. Evaluate UV & Weather Resistance

A high-quality pond liner should:

  • Contain carbon black for UV protection.

  • Withstand extreme temperatures (freezing winters to hot summers).

  • Resist algae growth and chemical degradation.

Tip: If the pond is exposed to direct sunlight, ensure the liner has UV stabilizers for a longer lifespan.

4. Consider Fish & Environmental Safety

For fish ponds or drinking water storage:

  • Choose non-toxic, fish-safe liners (EPDM or HDPE with NSF certification).

  • Avoid PVC liners, which may leach harmful chemicals over time.

Bonus: Textured liners provide better traction for fish and prevent slips.
