Product Description
Description:
Drainage geonet, also called Composite Geonet, is a two or three-layer three-dimensional drainage geosynthetic product which are often made with polypropylene PP or regenerated HDPE (called geonet) and covered with single- or double-sided thermally heat-bonded nonwoven geotextile on both sides or one side.
The geonet has high drainage performance which is made of high quality polyethylene resin, adding 2-3% carbon black, anti-UV and anti-oxidant processed by special extruding technology. Nuolian brand drainage net has excellent performance than traditional draining gravel. The 3D composite drainage net combines the characteristics and functions of geonet and geotextile, it has the comprehensive charateristics of anti-filtration, good drainage, air permeability and high strengthen and protection reinforcement. It is an ideal new drainage geo material.
What is Composite Triplanar Geonet?
Composite triplanar geonet, also known as triplanar geocomposite, is a type of geosynthetic material used in civil engineering and environmental applications. It combines different components to achieve specific engineering properties. The term "triplanar" refers to its three-dimensional structure, which typically consists of three layers
Functions and features of Composite Triplanar Geonet:
1.Drainage: One of the primary functions of composite triplanar geonets is drainage. The three-dimensional structure of the geonet core allows for efficient drainage of water from soil or other materials. This helps to reduce hydrostatic pressure, control groundwater levels, and prevent waterlogging in various applications such as retaining walls, landfills, and roadways.
2.Filtration: Composite triplanar geonets typically include geotextile layers on either side of the geonet core. These geotextile layers act as filters, allowing water to pass through while preventing the migration of fine particles. This helps to maintain the integrity of the drainage system by preventing clogging and ensuring long-term performance.
3.Separation: The geotextile layers of composite triplanar geonets provide separation between different soil layers or materials. This prevents the mixing of materials, maintains the stability of engineered structures, and enhances overall performance. Separation is particularly important in applications such as roadways, railways, and landfill liner systems.
4.Reinforcement: Composite triplanar geonets can also provide reinforcement to soil and fills materials. The three-dimensional structure of the geonet core helps to distribute loads more evenly, reducing stress concentrations and improving the mechanical properties of the soil or fill. This reinforcement enhances the stability and performance of structures such as embankments, slopes, and retaining walls.
5.Environmental Protection: Composite triplanar geonets play a crucial role in environmental protection by preventing the migration of contaminants in applications such as landfill liner systems and groundwater protection measures. The combination of filtration, drainage, and separation functions helps to contain pollutants and prevent them from contaminating the surrounding soil and groundwater.
