Engineering Drainage PP/PET Non-woven Geotextile
Non-woven geotextiles have the advantages of good water permeability, high tensile strength, strong pressure resistance, and resistance to acid and alkali corrosion.
It can be used in soil reinforcement, waterproofing, filtration, isolation, protection and other fields.
Non-woven geotextiles are produced using non-woven technology.
Material: PET/PP
Weight:100-800g
Width: 1-7m
Length: 50-200m (customizable)
Color; white, black, orange, supports custom colors
Non-woven geotextiles have the advantages of simple structure, stable performance, and easy use.
Features:
1. Filtration: When water flows from the fine soil layer into the coarse soil layer, the geotextile's good air permeability and water permeability allow the water to pass through and effectively intercept soil particles, fine sand, small stones, etc. To maintain the stability of water and soil engineering.
2. Drainage effect: Geotextile is a good water-conducting material. It can form a drainage channel inside the soil body and drain excess liquid and gas out of the soil structure.
3. Reinforcement: Use geotextiles to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil.
4. Protective effect: When the water flows against the soil, it effectively diffuses, transfers or decomposes the concentrated stress, preventing the soil from being damaged by external forces, and plays a role in protecting the soil.
5. Sealing and anti-puncture: combined with geomembrane to form a composite waterproof and anti-seepage material, which plays a role in preventing puncture.
Application:
1. Used as reinforcement in retaining wall backfill, or used to anchor retaining wall panels. Construct a wrapped retaining wall or abutment.
2. Reinforce flexible pavement, repair cracks on the road, and prevent pavement reflection cracks.
3. The isolation layer between road ballast and roadbed, or the isolation layer between roadbed and soft base.
4. The isolation layer between artificial fill, rock or material field and foundation, and the isolation between different frozen soil layers. Filtering and reinforcement.
5. The isolation layer of geotextile between highways, airports, railway ballast and artificial rockfill and the foundation.
