Products Introduction：
Geotextile Erosion Control is a functional geosynthetic material designed specifically to prevent soil erosion. It is made from polypropylene (PP) and polyester (PET) as core materials, and is produced through needle punched non-woven, woven or composite processes. Its core positioning is the "integrated barrier of ecological protection and erosion barrier". Through the triple functions of "physical interception, water flow diversion, and soil constraint", it resists rainwater erosion, water flow erosion, and wind erosion, solves problems such as "soil loss, slope collapse, and ecological damage" in scenarios such as slopes, bank slopes, and roadbeds, and is compatible with vegetation growth, providing a collaborative solution for engineering protection and ecological restoration.
Product Features：
1. Anti erosion soil consolidation, intercepting erosion sources
Adopting high-density fiber structure or composite reinforcement technology, with a surface friction coefficient of ≥ 0.5, it can effectively disperse rainwater impact force (withstand rainfall intensity up to 50mm/h) and constrain soil particle displacement; The longitudinal and transverse fracture strength is ≥ 15kN/m, and the tear resistance strength is ≥ 3kN. It can resist fabric damage caused by water flow erosion, prevent the migration and loss of loose soil and sandy soil particles, and reduce soil erosion by more than 80% in slope protection.
2. Ecological compatibility, assisting vegetation restoration
Needle punched non-woven or porous woven structures reserve vegetation growth space with a porosity of 60% -75%, allowing water and nutrient infiltration without hindering grass seed germination and root growth; Some products can be directly compounded with natural materials such as coconut fiber and straw to form an "geotextile+natural fiber" ecological blanket, which combines protection and greening functions, achieving synchronous "engineering protection ecological restoration" and adapting to ecologically sensitive erosion protection scenarios.
3. Flexible and snug fit, suitable for complex slopes
The product has a fracture elongation rate of 20% -45%, and can naturally fit curved slopes, steep slopes (slope ≤ 70 °), and irregular shorelines without any protective blind spots; Lightweight design (weight 100-400g/m ²) facilitates handling and cutting, even in narrow slopes in mountainous areas, curved bank slopes in rivers, and other construction space limited scenarios. It only requires manual installation and fixation, solving the pain points of rigid protective materials that are difficult to bend and prone to hollowing.
4. Weather resistant and corrosion-resistant, ensuring long-term protection
The raw materials have been treated with UV resistance, acid and alkali resistance, and biodegradation resistance, and can work stably in the extreme temperature range of -30 ℃ to 80 ℃. They are resistant to salt alkali soil, river water immersion, and outdoor strong sunlight aging; When buried or used on slopes, the service life can reach 5-15 years, during which there is no need for frequent replacement, greatly reducing maintenance costs in the later stage, and adapting to complex climate environments such as rainy, coastal, and high-altitude.
5. Efficient construction and controllable cost
Support roll laying, with a single roll length of 50-100m and a width of 2-6m, reducing the number of overlapping and splicing times, and achieving a manual laying efficiency of 600-1000 square meters per day; Without the need for large mechanical equipment, it can be fixed by simple methods such as nailing and overlapping. The material cost is reduced by 30% -50% compared to concrete slope protection, and the cost advantage of full cycle protection is significant, making it suitable for large-scale erosion protection projects.

1. Slope protection of transportation roads
Highway/railway slope: laid on the surface of road slopes to resist soil erosion caused by rainwater erosion and vehicle vibration, combined with spray greening to form a "protection greening" composite layer to prevent slope collapse, suitable for slope protection along mountain roads and high-speed railways.
Roadbed Slope and Shoulder: Used for roadbed slope and shoulder edges to prevent rainwater from infiltrating and softening the roadbed, while also preventing soil erosion and erosion of the shoulder, avoiding pavement overturning and cracking, and suitable for roadbed protection of highways and rural roads.
2. Water conservancy and river bank slope protection
River/reservoir bank slope: laid on the upstream slope of rivers and reservoirs to resist bank slope collapse caused by water flow erosion and water level changes, protect the ecological environment of riverbanks, and adapt to urban river ecological management and small and medium-sized reservoir bank slope protection projects.
