1. What Is Geomembrane Liner?
A geomembrane liner is a synthetic membrane or barrier with very low permeability used in conjunction with geotechnical engineering materials to control the migration of fluids (liquids or gases) in human-made projects, structures, or systems.
Geomembrane liners are impermeable membranes that work together with rocks or soil to prevent the movement of fluids in man-made structures. These liners are typically made of synthetic polymers and are available in sheets ranging from 0.5 to 3.0 mm (20 to 120 mil) in thickness. Common materials used for geomembrane liners include EPDM (Ethylene Propylene Diene Monomer), Linear Low-Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), and Polypropylene (PP). While geomembrane liners are primarily thin continuous polymeric sheets, they can also be made by impregnating geotextiles with asphalt, elastomers, or polymer sprays, or as multilayered bitumen geocomposites. Continuous polymer sheet geomembranes are the most commonly used type. These liners effectively block the movement of fluids, preventing the spread of contaminants, and can be used in combination with soil liners or permeable geotextiles to create composite lining systems that offer additional security.
Among the various types, HDPE geomembrane liners are often preferred for lining projects that require high liner strength. HDPE liners are resistant to many solvents and are the most widely used geomembrane liners worldwide. While they may be less flexible than LLDPE, HDPE liners provide higher specific strength and can withstand higher temperatures. Additionally, their ultraviolet resistance properties make them a cost-effective choice.
BPM geomembrane products are manufactured using durable virgin materials that can have an expected lifespan of hundreds of years. They are resistant to chemicals and wear, ensuring that the integrity of the geomembrane liner remains unaffected by the passage of time and corrosion. Each type of geomembrane liner material has specific characteristics that impact installation procedures, lifespan, and performance. BPM Geosynthetics offers a variety of materials tailored to the specific needs of your project.
