Quality Geomembrane Liner Materials

At GM Liners, we specialize in supplying and installing high-quality geomembrane liners for a wide range of civil engineering and environmental containment projects. 

Geomembranes are impermeable membranes used to control fluid or gas migration in a man-made structure or system.

From canals and reservoirs to landfills and mining operations, our liners are engineered to deliver long-term performance in even the most demanding conditions.

Uses for Geomembrane Liners

Geomembrane liners are impermeable membranes used to control fluid or gas migration in a man-made structure or system. 

Our liner solutions support the following benefits:

  • For environmental projects, we supply liners for landfills, wastewater ponds, and lagoons to prevent contaminants from getting into the soil and water system.

  • For conservation projects, including irrigation canals, reservoirs, and tanks, to minimize water loss through seepage.

  • Our liners secure chemical containment for heap leach pads and tailings dams.

  • We offer durable linings for animal waste lagoons, irrigation ponds, and ponds for waste and water management.

  • To protect surrounding areas, geomembrane liners are durable solutions for stormwater systems and secondary containment.

HDPE vs LDPE Geomembrane Liners:

Choosing the right geomembrane material depends on your project’s needs for flexibility, chemical resistance, and UV stability.

Each product page outlines specifications, applications, and downloadable data sheets to support your design and procurement process.

Frequently Asked Questions (FAQs) About Geomembrane Liners:

  • A geomembrane is a very low-permeability synthetic membrane liner or barrier. Its primary purpose is to control the movement of fluids (liquids or gases) in a project. It acts as an impermeable shield to prevent seepage, contain contaminants, and separate different materials.

  • Common applications include lining reservoirs, landfills, wastewater treatment ponds, and mining operations to ensure that potentially harmful liquids do not leak into the surrounding soil and groundwater.

  • When properly selected, installed, and protected, geomembranes have a very long service life. Many are engineered to last for decades, with HDPE liners often having design lives exceeding 30 years and potentially up to 100 years under ideal conditions.

    The key factors that influence their lifespan include:

    • Material Type

    • UV Exposure:

    • Chemical Exposure

    • Installation Quality

    • Physical Protection

  • The core difference is that HDPE is rigid and strong, while LDPE is flexible and conformable.

    HDPE (High-Density Polyethylene) is known for its exceptional tensile strength and high chemical resistance. Its stiff nature makes it ideal for large-scale containment projects with stable foundations, such as landfills, reservoir liners, and tailings dams, where impermeability and durability are the top priorities.

    LDPE (Low-Density Polyethylene) offers superior flexibility, elongation, and resistance to stress cracking. This allows it to conform to uneven subgrades and accommodate minor ground movement without failing. It is often the preferred choice for applications like agricultural lagoons, canal linings, and landfill caps where adaptability is crucial.
