Products Introduction：
Soil Stabilization by Geotextiles and Fabrics is an engineering solution that enhances soil structural stability by laying functional geotextiles or geotextiles and utilizing their reinforcing, isolating, and restraining effects. This system uses polymer fibers such as polypropylene (PP) and polyester (PET) as the core raw materials to produce woven, needle punched composite or reinforced geotechnical products, which are laid inside or on the surface of the soil. Through the "soil fabric synergy", it solves the problems of "insufficient bearing capacity, easy settlement, weak erosion resistance" of soft soil, loose soil, backfill soil and other foundation soils, and provides lightweight and low-cost soil reinforcement solutions for road, slope, building foundation and other projects.
Product Features：
1. Reinforcement synergy enhances soil bearing capacity
Geotextile/fabric is a three-dimensional network structure formed by interweaving fibers, tightly interlocking with soil particles to form a "composite stable layer". Its longitudinal and transverse fracture strength can reach 20-80kN/m, effectively transmitting and dispersing local loads borne by the soil (such as vehicle compaction and building self weight), reducing soil shear stress, increasing soil shear strength by 30% -60%, and bearing capacity by 2-3 times, avoiding settlement and collapse caused by load concentration, and adapting to heavy load scenarios such as roadbeds and building foundations.
2. Constraint resistance to prevent soil erosion and migration
The dense structure of fabrics can constrain the displacement of soil particles and prevent loose and sandy soils from undergoing particle migration under the influence of rainwater erosion and water flow infiltration; At the same time, as a physical barrier, it isolates soil layers of different gradations to prevent fine soil from mixing with coarse aggregate layers and causing structural failure. In slope protection, it can effectively suppress soil collapse and soil erosion, maintain slope stability, and adapt to erosion prone scenarios such as slopes in rainy areas and river bank slopes.
3. Flexible and adaptable, suitable for complex terrain conditions
The product combines toughness and ductility, with a fracture elongation controlled at 15% -40%. It can naturally fit irregular terrains such as potholed roadbeds, curved slopes, and steep base surfaces (with a slope of ≤ 60 °), without blind spots for laying. Lightweight design (with a weight of 150-500g/m ²) makes it easy to handle and cut, even in narrow excavations, curved ditches and other limited construction spaces, laying can be completed manually, solving the pain points of traditional rigid stable materials that are difficult to bend and prone to cracking.
4. Weather resistant and creep resistant, ensuring long-term stability effect
The raw materials have undergone anti UV, anti acid and alkali, and anti biodegradation treatments, and can work stably in the extreme temperature range of -35 ℃ to 85 ℃. They are resistant to erosion from saline alkali soil, groundwater immersion, and outdoor sun and rain exposure. Excellent creep resistance, with a deformation rate of less than 5% under long-term constant load, ensuring that the soil structure maintains a stable shape for a long time, with a service life of up to 10-20 years, greatly reducing the frequency of later maintenance.
5. Environmental protection economy, optimizing the full cycle cost of engineering
No need to add chemical amendments, avoiding damage to the soil ecological environment, in line with the concept of green engineering; Compared with traditional replacement and concrete reinforcement methods, the material procurement cost is reduced by 25% -45%, the construction efficiency is improved by 2-3 times (the manual laying speed reaches 500-800 square meters/day), the construction period is shortened while reducing labor and equipment investment, and the long-term maintenance cost is reduced by more than 40%. It is suitable for cost sensitive rural roads, large-scale slope reinforcement and other projects.
