Geomembranes can generally be divided into two categories: asphalt and polymers (synthetic polymers). Geomembranes containing asphalt are mainly composite (including woven or non-woven geotextiles), and asphalt is used as a wetting binder. Polymer geomembranes are divided into plastic geomembranes, elastic geomembranes, and composite geomembranes based on different main materials. A large number of engineering practices have shown that geomembranes have good impermeability, strong elasticity, and adaptability to deformation. They can be suitable for different construction conditions and working stresses, and have good aging resistance. The durability of geomembranes under water and in soil is particularly outstanding. Geomembranes have outstanding anti-seepage and waterproofing properties

Geocomposite materials

Geotextiles, geomembranes, geogrids, and certain special geosynthetic materials are formed by combining two or more of their materials.

. Geocomposite materials can combine the properties of different materials to better meet the needs of specific engineering, and can play a variety of functional roles. Composite geomembrane is a geotextile composition made from geomembrane and geotextile according to certain requirements Among them, geotextile is mainly used for anti-seepage, and geotextile plays a role in reinforcement, drainage, and increasing the friction between the geotextile and the soil surface. Another example is geotextile composite drainage material, which is a drainage material composed of non-woven geotextile, geotextile mesh, geotextile membrane, or geotextile core materials of different shapes. It is used for soft foundation drainage consolidation treatment, vertical and horizontal drainage of roadbed, underground drainage pipelines in buildings, water collection wells, wall drainage of supporting buildings, tunnel drainage, embankment drainage facilities, etc. The plastic drainage board commonly used in roadbed engineering is a type of geotextile composite drainage material. The geotechnical composite materials widely used for roads abroad are fiberglass polyester anti cracking fabric and warp knitted composite reinforced anti cracking fabric. It can extend the service life of roads, greatly reducing the cost of repair and maintenance. From the perspective of long-term economic benefits, it is necessary for China to actively adopt and promote geotextile composite materials
