Tri-Dimension Compound Geonet Durable And Corrosion-Resistant For Various Applications
Product Introduction
Thi-dimension compound geonet for drainage is made of a unique thi-dimension geonet and adhesive with geotextiles on both sides. It has the property of geotextile(filtration) and geonet(drainage and protection), it provide a complete function system" filtration-drainage-protection". The core of net with its unique tri-dimension structure can bear higher compressing load in construction and remanin the certain thickness, provide a good water conductivity.
Product Application
Darinage for the landfill, roadbed and road surface, railway, tunnel, underground structure, back of retaining wall, garden and playground, etc.
Product Property
1. Excellent drainage
The three-dimensional composite drainage network has the drainage performance equivalent to a meter thick of gravel drainage, capable of quickly draining moisture from the soil.
2. High tensile strength
This material has high tensile strength, reducing the chances of geotechnical fabric embedding into the mesh core, ensuring long-term stable drainage performance.
3. High Load-bearing Capacity
Three-dimensional composite drainage network can withstand about 3000 kPa of compressive load, and can maintain good drainage performance even under high load.
4. Durability
The material is corrosion-resistant, acid and alkali resistant, and has a long service life.
5. Easy Construction
Due to its lightweight and easy-to-lay features, the three-dimensional composite drainage net can shorten the construction period and reduce engineering costs.
In summary, three-dimensional composite drainage networks are an efficient and durable drainage material suitable for a variety of engineering scenarios.
