Frequently known within the industry as a liner, a geomembrane is an impervious synthetic material that is used to contain fluids or gasses. Geomembranes primarily serve as a barrier or shield that prevents various contaminates from spilling or leaking into the soil and groundwater. Geomembranes are utilized across various industries including waste management, industrial, energy, oil and gas, agriculture, transportation, and mining. They line landfills, reservoirs, ponds, tanks, canals, dams, sewers, roads, and highways.

Flexible Polyvinyl Chloride films (PVC) have been used in geomembrane applications for over 60 years. PVC, a flexible, elastic material, offers oil resistance, UV stability, low-temperature protection, and excellent puncture resistance. Utilizing a factory prefabricated PVC geomembrane reduces field seaming and overall construction time, producing cost savings for your project.

HDPE (High-Density Polyethylene) Geomembranes are the most widely used liners in the world. HDPE liners provide the highest resistance to chemicals and have excellent ultraviolet resistant properties. Polyethylene liners are fusion welded and air pressure tested. LLDPE (Liner Low Density Polyethylene) Geomembranes offer great flexibility in addition to resistance to low temperatures and ultraviolet exposure. LLDPE liners are easier to elongate or adapt to their environment, which allow for higher impact and puncture resistance.

XR-5®, a proprietary resin blend produced by Seaman Corporation for over 40 years, is the highest-strength and most chemically resistant geomembrane on the market. Engineered for the toughest applications, XR-5®contains and protects against acids, oils, methane, and alkalis. Some of these applications include floating covers, leachate ponds, tank floors, process and wastewater ponds, as well as secondary containment. XR-5® is flexible and can be prefabricated in large panels, allowing for efficient installation.

Polypropylene combines excellent elasticity, elongation, cold temperature stability, UV stability, and chemical defense in one material. Polypropylene allows for some of the most flexible fabricated geomembranes. Large panels can be factory prefabricated for ease of installation.

CSPE, commonly known as Hypalon, is a reinforced flexible and durable geomembrane that offers excellent resistance to chemicals, temperature, UV degradation, as well as organic and inorganic chemicals. Similar to Polyethylene, PVC, and XR-5®liners, Hypalon is prefabricated in large panels, allowing for swift deployment and time saving installation. Having a long-standing history in the industry, Hypalon has often been specified in the fabrication of floating covers. Ask us which Geomembrane is best suited for your next project
