plastic woven film yarn geotextiles
Plastic flat woven geotextile
Woven geotextile is a geosynthetic material woven from polypropylene and polypropylene ethylene tape as raw materials. It is widely used in geotechnical engineering such as water conservancy, electric power, harbor, highway and railway construction.
1. High strength Due to the use of plastic flat wire, it can maintain sufficient strength and elongation in dry and wet conditions.
2. Corrosion resistance It can resist corrosion for a long time in soil and water with different pH.
3. Good water permeability There are gaps between the flat wires, so it has good water permeability.
4. Good anti-microbial properties, no damage to microorganisms and moths.
5. Convenient construction Because the material is light and soft, it is convenient for transportation, laying and construction.
