Beijing Hualong geotechnical materials company   

        geotextiles are polypropylene, polyester filament for geosynthetic materials through woven, widely used in water conservancy, electric power, railway, highway, harbor construction in geotechnical engineering.  
it has the following characteristics of  
1, high strength, due to the use of plastic, can maintain adequate strength and elongation under dry and wet conditions.  
2, corrosion resistance, can be a long time corrosion in soil and water in different pH.  
3, good water permeability,   there are gaps in the flat, so the seepage properties of good.  
4, microbial resistance good   on microbial, moth eaten are not damaged.  
5, construction is convenient, the material is light, soft, so transporting, laying, convenient construction.  
6, specifications:   up to 6 meters width. Is currently the most wide products, mass per unit area: 100-600g/ square meters.  
is applied to water conservancy, embankment, road, airport, construction, environmental engineering, can play a role in filtration, drainage, isolation,   door, reinforced the role;
