Products Introduction：
Geo Fabric Material is a type of functional geosynthetic material made from high molecular weight polymers such as polypropylene (PP) and polyester (PET) through processes such as weaving, needle punching, non-woven, and thermal bonding. It is the "foundation protection and reinforcement core" in the field of civil engineering. Its core value lies in the flexible combination of the five basic functions of "isolation, filtration, reinforcement, drainage, and protection" to solve common problems such as unstable soil structure, mixed engineering materials, and water retention, providing lightweight and low-cost structural optimization solutions for various projects.
Product Features：
1. Multi functional integration, adapted to common engineering requirements
It has five core functions: isolation, filtration, reinforcement, drainage, and protection. The isolation function can separate soil and building materials of different grades to prevent mixing between layers; The filtering function intercepts fine particles to ensure smooth drainage; Strengthening function enhances the bearing capacity of soil; Drainage function to divert moisture and prevent water accumulation; The protective function reduces the wear and impact of external forces on the structure. Different types of geotextiles can focus on a specific function or collaborate with multiple functions to meet the diverse needs of engineering.
2. Adjustable mechanical properties, suitable for different stress scenarios
By selecting raw materials and adjusting processes, the mechanical properties are flexible and controllable: the longitudinal and transverse fracture strength of woven geotextiles can reach 15-150kN/m, suitable for heavy-duty reinforcement scenarios; The fracture elongation rate of non-woven geotextile is 20% -50%, suitable for flexible bonding requirements. At the same time, it has excellent tear resistance and puncture resistance, and can resist external forces such as construction machinery rolling and soil friction, ensuring the stability of the engineering structure.
3. Weather resistant, corrosion-resistant and durable, with a wide range of environmental adaptability
The raw materials have undergone anti UV, anti acid and alkali, and anti microbial degradation treatment, and can be stably used in the extreme temperature range of -40 ℃ to 90 ℃. They are resistant to saline alkali soil, groundwater immersion, outdoor sun and rain exposure, and industrial environment erosion. The buried service life can reach 5-25 years, and the exposed service life can reach 3-10 years, significantly reducing the frequency and cost of maintenance in the later stage of the project.
4. Flexible and easy to lay, compatible with complex working conditions and processes
The texture is soft and has good extensibility, which can naturally fit irregular terrains such as undulating surfaces, curved slopes, narrow ditches, etc., without blind spots for laying; Lightweight and easy to cut, the length of a single roll can reach 50-200m, and only manual labor or small machinery is needed to complete the laying, with a construction efficiency of 500-1000 square meters per day. Simultaneously compatible with subsequent processes such as asphalt paving, concrete pouring, and crushed stone compaction, without the need to adjust the engineering process.
5. Economic and environmental protection, optimizing the full cycle cost of engineering
The material cost is only 1/5-1/2 of traditional rigid materials such as concrete and steel plates, and the construction does not require large equipment, reducing labor costs by more than 30%; In long-term use, due to the improvement of structural stability, the maintenance cycle of the project is extended by 2-5 times, and the overall cost advantage is significant. In addition, polymer raw materials can be recycled, and some products are made of recycled materials, which is in line with the concept of green engineering.
