Geotextile 110g m2
1. Lightweight and easy to construct
Geotextile is lightweight and easy to transport and lay, which can significantly reduce the dependence on construction machinery and lower labor costs. It is especially suitable for operations in complex terrains or narrow spaces.
2. High strength and good durability
Polymer materials themselves have high tensile strength, tear strength, acid and alkali resistance, corrosion resistance, and UV aging resistance, making them suitable for harsh engineering environments.
3. Balance between permeability and filtration
It can not only allow water to pass through, but also prevent soil particle loss, avoiding "piping" or foundation settlement in engineering.
Product Introduction:
Geotextile 110g m2 is a permeable geosynthetic material made from high molecular weight polymers (such as polypropylene, polyester, polyethylene, etc.) through processes such as needle punching, weaving, and spinning. It is mainly used in fields such as geotechnical engineering, water conservancy engineering, and transportation engineering. Through its mechanical properties, filtration performance, drainage performance, etc., it achieves engineering functions such as reinforcement, protection, isolation, and filtration.
Simply put, geotextile is a "textile in geotechnical engineering" that retains the flexibility of the fabric while also possessing durability to adapt to the engineering environment.
characteristic
1. Clear classification
Needle punched non-woven geotextile: made by randomly arranging short fibers and needle punched reinforcement, with good breathability and strong filtration, suitable for soft foundation treatment and drainage engineering.
Woven geotextile: woven from long or flat fibers, with high tensile strength and good wear resistance, suitable for dam reinforcement and road base.
Composite geotextile: Combining non-woven and weaving techniques, it combines filtration and high strength, and is used in complex engineering scenarios such as landfills.
2. Multifunctionality
A single material can simultaneously achieve multiple functions, such as isolating different soil layers (avoiding mixing), draining (preventing water accumulation), and enhancing the bearing capacity of the foundation (reinforcing effect) in the roadbed.
3. Strong adaptability
It can customize specifications according to engineering requirements (such as thickness, strength, and width), and can adapt to different terrains (such as steep slopes and wetlands), even working normally in underwater environments.
4. Stable weather resistance
Capable of withstanding temperature changes ranging from -40 ℃ to 80 ℃, resistant to ultraviolet radiation and biological erosion (such as microbial decomposition), with stable performance in outdoor or underground environments.

Product Applications:
1. Water conservancy engineering
Dam protection: As a filter layer and drainage layer, it prevents infiltration damage and enhances flood resistance.
Channel lining: reduces water leakage, improves water delivery efficiency, and protects slope soil.
2. Transportation Engineering
Road base: Isolate aggregates of different particle sizes to prevent mixing and ensure road surface smoothness and durability.
Railway track bed: Drainage isolation to prevent ballast from being embedded in the roadbed and reduce track deformation.
3 Environmental Protection Engineering
Landfill site: forms an anti-seepage system with geomembranes, drainage networks, etc., to prevent leachate pollution.
Wastewater treatment plant: As a biological filter material, it improves the efficiency of wastewater treatment.
4. Architecture and Municipal Administration
Basement waterproofing: In combination with waterproof coatings and rolls, it enhances the ability to resist tearing and punctures.
Roof greening: Fixed planting soil, water retention and ventilation, promoting vegetation growth, and achieving ecological restoration.
5. Family and Horticulture
Grass proof cloth: Covering garden and vegetable fields, suppressing weeds, and reducing pesticide use.
Emergency waterproofing: Temporarily cover the roof leakage point to prevent indoor water immersion.
Moving and storage: Wrap furniture corners to prevent scratches, and lay them at the bottom of the carriage to prevent goods from sliding.
Geotextiles use "small materials" to solve the problems of "big projects". From thousands of miles of highways to home gardens, from flood control embankments to landfills, their value has surpassed the traditional material category and become the "connector" between modern engineering and ecological protection. In the future, with technological iteration, geotextiles will continue to demonstrate the hardcore strength of "invisible guardians" in more fields.
