Overview

DGSL Pond Liner in a 20 mil HDPE formulation brings a balance of flexibility and strength to outdoor water features. The material is malleable enough to form to irregular banks and gentle slopes, yet robust enough to resist punctures and tears under typical garden conditions. It is plasticizer-free, designed for long-term outdoor use where water clarity and containment matter. This liner helps you create natural-looking edges and smooth contours in a variety of ponds, from koi habitats to decorative water gardens.

Designed with real-world use in mind, the DGSL liner supports projects that blend with landscapes while providing dependable containment. It is sized to fit smaller installations, and the 20 mil thickness offers a practical balance of durability and manageability for weekend DIYers and hobbyists alike.

Key benefits

  • Durable HDPE construction that resists punctures, tears, and chemical spills while withstanding harsh environments.
  • Flexible enough to conform to irregular surfaces and slopes, enabling smooth, natural edges.
  • DIY-friendly 12x12 ft size that’s suitable for smaller ponds and easy to handle during installation.
  • 20 mil thickness provides a robust yet workable barrier for outdoor setups and seasonal changes.
  • Underlayment-friendly design allows a flat base, with optional pebble layering to cushion and beautify.

Versatile applications

This liner supports a wide range of outdoor water features, including koi ponds, water gardens, retention or containment ponds, and backyard waterfalls. It works well on uneven terrain and can be trimmed to fit custom shapes, helping you achieve a natural look without compromising containment.

  • Ideal for koi ponds, small water gardens, and decorative water features with gentle slopes.
  • Suitable for both above-ground and below-ground installations, depending on landscape plans.

Installation tips

  • Lay a flat underlayment first to create a smooth base and reduce wear over time.
  • Unfold and position the liner, leaving extra material at the edges for trimming.
  • Trim to fit your pond shape, following contours and avoiding sharp folds.
  • Consider adding a layer of round pebbles before final placement to cushion edges and enhance appearance.
