Product Introduction:
Geotextile 300gr is a permeable geosynthetic material made from synthetic fibers such as polyester, polypropylene, nylon, etc., through processes such as needle punching, weaving, weaving, or spinning. It is not a traditional "fabric", but a functional material with specific engineering properties, mainly used for contact with media such as soil, rock, water, etc., to play a role in reinforcement, isolation, filtration, drainage, etc.
characteristic
1. Excellent physical performance
High strength: Strong tensile, tear resistance, and puncture resistance, capable of withstanding construction and long-term loads.
Good flexibility: able to adapt to foundation deformation, closely adhere to soil, and reduce the risk of uneven settlement.
Strong durability: Wear resistant, UV resistant (some parts have been specially treated), long service life.
2. Permeability and Filtration
Excellent permeability: allowing water to pass freely while effectively preventing soil particle loss and clogging.
Anti filtering effect: It can replace traditional sand and gravel filter layers in hydraulic engineering and protect the stability of soil structure.
3. Chemical stability
Corrosion resistance: acid and alkali resistance, mold resistance, suitable for harsh environments such as saline alkali land and swamps.
Anti biodegradation: Not easily damaged by microorganisms, insects, and ants, maintaining stable performance over the long term.
4. Construction convenience
Lightweight and easy to lay: Lightweight, convenient for transportation, cutting, and mechanized construction, improving efficiency.
Strong adaptability: can be applied to different terrains (such as steep slopes, soft foundations) and complex engineering requirements.
5. Environmental Protection and Economy
Reduce natural material consumption: Replace traditional materials such as sand, gravel, and clay to reduce resource extraction.
Recyclable: Some geotextiles are recyclable, in line with the concept of sustainable development.
Low overall cost: fast construction, minimal maintenance, and significant long-term economic benefits.
