A geomembrane is a film or sheet made of plastic material with a certain degree of impermeability and chemical resistance. It is often used in civil engineering to prevent moisture penetration or to block penetration between layers of different materials. Common geomembrane materials include high-density polyethylene (HDPE), polypropylene (PP), polyester (PET), etc. Different types of

Do Tunnels Need Geotextiles? Geotextiles are usually not required in tunneling projects, but in some cases their use may provide additional advantages and benefits. Here are some possible situations where geotextiles are used: Preventing Soil Erosion: During tunneling, the stabilization and retention of soil is critical. Geotextiles can be used to control and reduce soil

Why is geomembrane used in tunnel engineering? 1. Waterproof protection: geomembrane can play a waterproof role, effectively preventing groundwater, surface water and rainwater from penetrating into the tunnel structure. Tunnel engineering often requires a lot of excavation and groundwater control. Geomembrane can provide a reliable waterproof barrier to avoid water erosion and damage to the
