Geotextile, geomembrane, geogrid, and certain special geosynthetics, when two or more of them are combined with each other, become geocomposite. Geotechnical composite materials can combine the properties of different materials to better meet the needs of specific projects and play a variety of functions. For example, composite
HDPE geomembrane for sale is a kind of geomembrane and geomembrane made according to certain requirements.
Among them, high quality HDPE geomembrane is mainly used to prevent seepage, and geomembrane plays the role of reinforcement, drainage and increasing the friction between geomembrane and soil surface. And as geotechnical composite drainage material, it is a non-woven geotextiles and geonet, geomembrane, or different shapes of geosynthetic materials drainage material consisting of a core material used in drainage consolidation of soft ground treatment, subgrade drainage, construction of underground pipes, collecting well, retaining wall of the building drainage drainage, drainage dam, tunnel, etc. The plastic drainage board commonly used in roadbed engineering is a kind of geotechnical composite drainage material.
A large number of geotechnical composite materials used in road abroad are glass fiber polyester anti-crack cloth and warp knitted reinforced anti-crack cloth. It can prolong the service life of the road, thus greatly reducing the cost of repair and maintenance. Considering the long-term economic benefits, geotechnical composite materials should be actively adopted and advocated in China.
