High Density Polyethylene Geomembranes (HDPE)
HDPE geomembranes are the most commonly used geomembrane in the world for a variety of reasons. HDPE geomembranes are used in a variety of primary and secondary applications, such as landfill liner systems, mining and mineral processing operations, ponds, wastewater treatment facilities, agricultural operations. They are also used to transport potable water and waste liquids. They are low-cost, UV resistant, durable, and have a high resistance to chemicals and environmental stressors. In addition to HDPE geomembranes being highly resistant to harsh chemicals, they are non-toxic and chemically inert, making them an ideal choice for lining potable water reservoirs in various countries. In addition, high density polyethylene liners have a long lifespan, which makes them a cost-effective option for long-term projects. As a result, it is no wonder that HDPE geomembranes are the material of choice for so many containment applications.
Linear Low Density Polyethylene Geomembranes (LLDPE)
Liner low density polyethylene geomembrane liners are mostly used in primary and secondary containment applications where flexibility and elongation are important design parameters such as: landfill covers, leachate collection systems, secondary containment liners, canals, reservoirs, golf course ponds, and coal ash impoundments. LLDPE liners are also used in potable water storage applications, aquaculture. and in combination with other geosynthetic systems. One of the properties that make LLDPE geomembrane liners so popular is their chemical resistance. They are resistant to a wide range of chemicals similar to HDPE. Additionally, they have superior flexibility even at low temperatures, making them ideal for use in a variety of buried and exposed containment applications in Canada.
Bituminous Geomembranes (BGM)
Bituminous geomembranes are a popular choice for geosynthetic systems including primary or secondary containment in a variety of industries, including mining in British Columbia, Alberta, the Northwest Territories, Yukon, and Ontario. These geomembranes, made from bitumen and reinforcing materials such as polyester or fiberglass, are known for their high strength, durability, and chemical resistance. They can be used as liners for landfills, ponds, and reservoirs, and also serve as effective waterproofing membranes for roofs, foundations, and underground structures. Available in various thicknesses and sizes, bituminous geomembranes are a versatile solution for a range of containment applications.
Geosynthetic Clay Liners (GCL) - coming soon!
Geomembrane liners, such as geosynthetic clay liners (GCLs), are composite materials specifically designed to provide an impermeable barrier to the passage of fluids in various geosynthetic systems, including landfills, dams, canals, ponds, tunneling applications, and in conjunction with other geosynthetic systems. GCLs consist of a bentonite layer sandwiched between two layers of geotextile that are mechanically stitched together, and they are often used in primary and secondary containment applications where long-term protection is required. The barrier performance of GCLs is derived from the unique properties of bentonite, which swells and seals when it comes into contact with water, creating a low-permeability barrier that prevents the passage of liquids and gases. The use of GCLs offers many benefits over traditional compacted clay liners, including improved flexibility, compatibility with uneven surfaces, and reduced installation costs, and they are less susceptible to cracking and leaching. When used together with geocomposite clay liners, GCLs can reduce the thickness of the traditional clay liner and create a high-performing, impenetrable barrier.
Geomembranes
Geomembranes are low-permeable thin polymeric sheets used in a variety of applications including capture of hazardous liquid spills, containment of leachate and storage of various liquids including potable water, wastewater, oil and chemicals. Geomembranes or commonly referred to as liners, are made of flexible materials that are impermeable to liquid and gas. They are used in a variety of environmental protection containment applications, such as landfill and wastewater containment, mining and oil & gas operations, agriculture, various waste conveyance canals, such as those that carry sewage sludge, liquids, and other wastes. Geomembrane liners provide many benefits over traditional methods of containment, such as compacted clay liners (CCL's). They are less expensive and faster to install, reduce carbon footprint, and more resistant to chemical and mechanical degradation. There are many different types of geomembrane liners (polyvinyl chloride [PVC], polyethylene, polypropylene, geosynthetic clay liners, bituminous , etc.) each with its own unique properties and suitable application.
What are geomembranes?
The selection of an appropriate geomembrane is a critical design decision that must take into account a number of factors, including the intended use of the geomembrane, the chemical and physical properties of the contaminants, and the climatic conditions at the project site. In addition, the thickness of the geomembrane should be carefully considered in relation to its target application. Generally speaking, thicker geomembranes are more resistant to punctures and tears, making them well-suited for high-stress applications. Conversely, thinner geomembrane liners are more pliable and easier to handle during installation, making them a good choice for less demanding containment applications. Ultimately, the goal is to select a geomembrane that is durable enough to withstand the anticipated loads while still being cost-effective. With this in mind, designers must carefully consider all of these factors to find the right type of liner for their projects.
