Three-Dimensional Composite Drainage Network Next-Generation Geosynthetic Material
Product Introduction
Three-dimensional composite drainage mesh is a new type of geosynthetic material, which is composed of three-dimensional geomesh core and needle-perforated non-woven geotextiles stuck on both sides. This structure makes the three-dimensional composite drainage network have high drainage performance and good filtration effect, and can effectively protect the soil and buildings from the influence of seepage deformation.
Product Property
1. Strong drainage: Its drainage performance is equivalent to one meter thick gravel drainage.
2. High tensile strength: can withstand high external forces without breaking.
3. Corrosion resistance, acid and alkali resistance: It has good chemical stability and is not easily affected by environmental factors.
4. Long service life: Due to its durable characteristics, it can maintain long-term performance in a variety of harsh environments.
Product Application
Three-dimensional composite drainage network is widely used in underground drainage projects in civil engineering, transportation, water conservancy, civil construction and mining, environmental protection and other fields because of its unique drainage and filtration performance. Especially in the application of landfill, roadbed and tunnel wall, it can effectively collect and discharge water seepage in the soil, reduce groundwater pressure, and protect the safety of soil and buildings.
