Geotech Fabric for Driveways
1. Enhance foundation stability: disperse loads and reduce uneven settlement.
2. Isolate different soil layers: prevent soil mixing and maintain structural integrity.
3. Drainage and water diversion: Accelerate the discharge of water and prevent the foundation from softening due to accumulated water.
4. Protective function: prevent soil erosion, protect slopes and riverbanks.
5. Convenient construction: lightweight, easy to cut, and high laying efficiency.
Product Introduction:
Geotech Fabric for Driveways is a permeable geosynthetic material made from synthetic fibers such as polyester (PET) and polypropylene (PP) through needle punching, weaving, or thermal bonding processes. The finished product is in the form of a cloth, with a width of generally 4-6 meters (some up to 9 meters) and a length of 50-100 meters. It is divided into woven geotextile (fiber oriented arrangement, high strength) and non-woven filament geotextile (fiber random arrangement, high porosity, good flexibility).
characteristic
1. High strength and ductility
Plastic fiber materials (such as polyester and polypropylene) endow geotextiles with sufficient strength and elongation in both dry and wet states, high tensile strength, and the ability to withstand large tensile forces without easily breaking.
2. Corrosion resistance and aging resistance
Long term acid and alkali corrosion resistance, microbial and insect resistance, and adaptability to different geological environments (such as saline alkali land and humid soil).
With a lifespan of several decades, it reduces maintenance costs in the later stages.
3. Permeability and Filtration
The gaps between fibers form permeable channels, allowing water to pass through but blocking soil particles, fine sand, etc., preventing soil erosion.
4. Lightweight and easy to construct
The material is soft and easy to transport, cut, and lay, and construction can be completed manually, reducing labor costs.
Supports multiple connection methods such as stitching, welding, and overlapping to adapt to complex terrains.
5. Environmental protection and multifunctionality
Non toxic and harmless, recyclable and in line with green engineering requirements.
It has functions such as isolation, reinforcement, protection, drainage, and insulation, and is versatile.

Product Applications:
1. Transportation Engineering
Roadbed reinforcement: isolate soil and sand to prevent material mixing from causing collapse and enhance the bearing capacity of the foundation.
Road maintenance: repair cracks, prevent reflection cracks, and reduce maintenance frequency.
2. Water conservancy engineering
Embankment protection: resist water erosion, protect structural integrity, such as river embankments and slope protection projects.
Drainage system: As a drainage material for reservoirs, mines, and farmland irrigation, it improves drainage efficiency.
3. Environmental Protection Engineering
Landfill: Wrap waste to prevent harmful substances from seeping into soil and groundwater.
Wastewater treatment: As a filtering material, it purifies water quality.
4. Architecture and Municipal Administration
Foundation treatment: As a reinforcement material for weak foundations, it enhances the bearing capacity.
Anti seepage and anti filtration: combined with geomembrane to form a composite waterproof material, used for anti-seepage in tunnels and basements.
5. Agriculture and Landscape Architecture
Grass proof cloth: Covering the soil surface, inhibiting weed growth, and maintaining soil moisture.
Irrigation and drainage: Improve the efficiency of farmland irrigation and prevent soil salinization.
6. Emergency and Civil Use
Temporary leak prevention: When there is water leakage on the roof or balcony, use geotextile to temporarily cover the drainage.
Moving and storage: Fragile items in the package are scratch resistant and placed at the bottom of the carriage to prevent slipping.
Outdoor camping: Lay it under the tent to prevent moisture and mud, and cut it into picnic mats for use.
Geotextile solves the problem of "large-scale engineering" with "small materials", and its high strength, corrosion resistance, permeability and other characteristics make it a core material in fields such as transportation, water conservancy, and environmental protection. With the advancement of technology, geotextiles are moving from professional engineering to daily life, such as home grass prevention, emergency leak prevention and other scenarios, demonstrating the infinite possibilities of "hardcore technology close to life". In the future, with material innovation (such as PET spunbond filament geotextiles) and process upgrades, the application boundaries of geotextiles will continue to expand, providing stronger support for global infrastructure construction.
