    Industrial

    HDPE-lined lagoons are used for chemical containment, tailings impoundment, and food processing waste management.

  • geosynthetic liner for golf courses

    Civil, Infrastructure and Recreational

    Geosynthetic lagoon liners can be used for stormwater retention, golf courses, and civil infrastructure projects.

  • Mining Evaporation Pond

    Mining

    For miners of precious metals, lithium, salts, and carbon products, EFI liners provide reliable containment for leachate ponds, evaporation ponds, and coal ash ponds.

  • Water Deluge for space launch

    Specialty Applications / Space / Deluge

    EFI liner systems are installed at the Kennedy Space Center to contain and retain water deluge system flow during space launches.

Technical Guide: Engineered Geosynthetic Liners & Containment Systems

Geosynthetic liners are impermeable membranes used to stabilize soil and prevent the migration of contaminants in industrial, agricultural, and municipal applications. Selecting the appropriate polymer depends on chemical compatibility, puncture resistance, and UV exposure requirements.

Comparison of Geosynthetic Liner Materials

Liner material is governed by site-specific variables, including subgrade stability and chemical concentrations.

  • High-Density Polyethylene (HDPE): Highly chemical-resistant and strong; the standard for large municipal and mining applications such as landfills and leach pads.

  • Linear Low-Density Polyethylene (LLDPE): More flexible and stretchable; adapts to uneven ground and handles settling—ideal for reservoirs and decorative ponds.

  • Polyvinyl Chloride (PVC): Flexible and easy to weld; suitable for complex shapes or temporary containment.

  • Reinforced Polypropylene (RPP): Strong and chemically resistant; designed for long-term exposure to harsh chemicals.
