When selecting a geomembrane liner for a project, there are several important considerations that need to be taken into account. From the material and manufacturing process through to the thickness of the sheet, it is important to carefully evaluate each option in order to choose the best liner for your particular needs. The Geomembrane Material Geomembrane liners are made from a variety of different materials, each with their own unique characteristics and potential benefits. Popular geomembrane liner materials include High Density Polyethylene (HDPE), Linear Low Density Polyethylene (LLDPE), and Ethylene Vinyl Acetate (EVA). Understand the differences between each material in order to select the best one for your particular application. The Thickness of the Liner While each geomembrane liner has its own thickness requirements, generally the thicker the liner, the better it is at protecting against punctures and tears. Keep in mind that although a thicker geomembrane liner can provide more protection, it will also cost more to purchase and install. Consider your project’s unique needs when selecting a geomembrane liner based on thickness. Types of Fittings and Connectors Fittings and connectors are necessary components of any geomembrane liner system. During the installation process, these components are used to make continuous connections between geosynthetic layers as well as transition from one layer to another. When selecting a geomembrane liner, be sure to confirm that compatible fittings and connectors will be available for your project. Cost Analysis When selecting a geomembrane liner, cost analysis of fittings and connectors should be taken into account. While most geosynthetic liners are relatively straightforward in terms of installation requirements, fittings and connectors require additional consideration as they can significantly increase overall project costs depending on the type of connector used. It’s important to check with your supplier or installer to understand the estimated cost of connecting your geomembrane liner before purchasing materials. Installation Guidance Make sure you understand the specific installation guidelines for connecting geomembrane liners when you purchase them. These connectors can be challenging to install, with special tools and procedures required for proper installation. Having a qualified installer on hand is highly recommended when dealing with fittings and connectors. Additionally, some geomembrane liner manufacturers offer installation training courses or evenon-site instruction customized to match your particular project.
