Appearance: The finished product is in the shape of cloth, with a texture similar to felt, soft to the touch, and has a certain degree of flexibility.
Core functions:
Isolation: Materials with different physical properties, such as soil and sand, soil and concrete, can be isolated to maintain the overall structure and function of the materials and enhance the load-bearing capacity of the structure.
Filtering: When water flows from the fine soil layer into the coarse soil layer, it can allow water to pass through while effectively intercepting soil particles, fine sand, etc., maintaining the stability of the water and soil engineering.
Drainage: It has good water conductivity and can form drainage channels inside the soil to discharge excess liquids and gases from the soil structure.
Reinforcement: can enhance the tensile strength and deformation resistance of soil, improve soil quality, and enhance foundation stability.
Protection: When water flows on the soil, it can diffuse, transmit or decompose concentrated stress, preventing the soil from being damaged by external forces and protecting the soil.
Main features:
High strength puncture resistance: With high tensile strength, some products can grip and stretch up to 380 pounds, withstand significant tensile forces, and resist sharp object punctures.
Good durability: UV resistant, anti-aging, acid and alkali resistant, non rotten, non moldy, resistant to rodent and insect damage, and can be used outdoors for a long time.
Good permeability: With high permeability, it can effectively discharge water and prevent soil particle loss, providing a good filtering effect.
Convenient construction: The material is lightweight, soft and easy to bend, convenient for transportation and laying, able to adapt to complex terrain, reduce construction difficulty, and improve construction efficiency.
Dimensional stability: The needle punching process stabilizes its fiber structure, making it less prone to significant deformation or shrinkage under stress or environmental changes

Product Application
Road construction field
16 ounce geotextile plays an important role in road base and subgrade treatment. It can be laid between the subgrade soil and the sand and gravel base, serving as a barrier to prevent mixing of different materials, avoiding deformation of the subgrade soil caused by sand and gravel compression, and enhancing the overall stability of the subgrade. In road maintenance engineering, laying it between the old road surface and the new layer can effectively disperse vehicle loads, reduce the risk of road cracking, and extend the service life of the road. In addition, in embankment construction, it can improve the anti settlement ability of embankments through reinforcement, especially suitable for soft soil foundation sections.
Water conservancy engineering field
In hydraulic engineering, 16 ounce geotextile is widely used. In the construction of flood control embankments and dams, it can be used as an anti filter layer to be laid on the upstream or downstream surface of the dam, which can not only facilitate the smooth discharge of seepage, but also block the loss of soil particles, prevent the occurrence of dangerous situations such as pipe surges in the dam, and ensure the safety of the dam. In channel lining engineering, laying between soil and lining materials can serve as isolation and drainage, reducing damage to the channel caused by soil settlement or water flow erosion. Meanwhile, in river regulation projects, it can be used for riverbank protection, resisting the erosion of water flow on the riverbank and protecting the riverbank structure.
Mining engineering field
In the construction of tailings dams in mining engineering, 16 ounce geotextile is an important protective material. It can be installed in the dam structure of the tailings dam to play a filtering and drainage role, effectively removing water from the tailings and preventing dam collapse accidents caused by excessive water accumulation. In addition, in the land reclamation project after mining, the use of this geotextile can isolate different levels of soil, improve soil structure, and create favorable conditions for vegetation restoration.
Landscape greening and agricultural field
In landscaping, 16 ounce geotextile can be used for base treatment of landscape roads and parking lots to prevent road settlement and weed growth. In the planting area, laying it on the surface or bottom of the soil can play a role in water retention, drainage, and preventing soil compaction, which is beneficial for the growth of plant roots. In the field of agriculture, it can be applied to the anti-seepage and drainage of irrigation channels in farmland, improving the efficiency of water resource utilization. At the same time, in the foundation treatment of greenhouses, it can enhance the stability of the foundation and reduce the deformation of the greenhouse caused by foundation problems.
16 ounce geotextile has wide and important applications in road construction, water conservancy engineering, mining engineering, landscaping, and agriculture due to its high strength, durability, and good permeability. It effectively enhances the stability, safety, and durability of various engineering projects through functions such as isolation, filtration, drainage, reinforcement, and protection, reduces maintenance costs, and provides reliable material support for engineering construction and sustainable development in different fields.
