1. What Is a High Density Pond Liner?

A High Density Pond Liner is a geosynthetic geomembrane, typically made from High-Density Polyethylene (HDPE), designed to prevent water seepage in ponds, reservoirs, and containment systems. Produced through a three-layer co-extrusion process, HDPE liners achieve uniform thickness (0.3–3.0 mm) and high tensile strength (15–30 MPa), meeting ASTM D412 standards. With a density of 0.94–0.96 g/cm³, these liners offer superior puncture resistance (2.5–5.0 kN) and low permeability, ensuring 99.9% water retention, per ASTM D4716. According to BPM Geosynthetics, HDPE pond liners account for 70% of global pond applications due to their NSF/ANSI 61 certification for fish safety, UV resistance for 15–20 years, and 90% chemical resistance against acids, alkalis, and salts, making them ideal for harsh environments like aquaculture farms and industrial wastewater ponds.

HDPE pond liners are supplied in rolls (3–10 m wide, 10–200 m long) or custom-fabricated panels, accommodating projects from small garden ponds (20 m²) to large reservoirs (50,000 m²). Their lightweight design (0.8–2.0 kg/m²) reduces transportation costs by 15–20% compared to alternatives like concrete, per Western Liner. Drain nets, often integrated with HDPE liners, are geocomposite drainage layers (typically 5–10 mm thick) made from HDPE or polypropylene nets encased in geotextile, enhancing water flow and reducing hydrostatic pressure by 80%, per Geotest. This combination ensures structural stability and longevity, critical for dredge-related applications like sediment containment and dewatering.
