Geocell Silknet
1.Three-Dimensional Reinforcement:
The honeycomb structure effectively confines infill materials, significantly enhancing overall shear strength and stability.
2.Lightweight yet High-Strength:
Made of polymer materials with excellent corrosion resistance and anti-aging properties, offering high load-bearing capacity with minimal weight per unit area.
3.Permeable Drainage:
Cellular structure allows water penetration, effectively reducing hydrostatic pressure.
Product Introduction:
Geocell Silknet is a three-dimensional honeycomb-structured geosynthetic material made of polymers (such as HDPE, PP, etc.), formed by stretching, welding or plugging. After unfolding, it can form a three-dimensional grid structure. Filled with materials such as earth-rock, sand-gravel or concrete, it can significantly enhance the bearing capacity of the foundation and prevent soil erosion. It is widely used in projects such as subgrade reinforcement, slope protection, and river regulation.
Performance Characteristics
High Strength and Stability: The geocell is made of high-strength HDPE or PP materials, featuring high tensile strength and tear resistance, enabling it to withstand large external loads. The strength at the welded points is also high, ensuring the integrity and stability of the geocell structure, making it less likely to be damaged during long-term use.
Good corrosion resistance and anti-aging properties: HDPE and PP materials have stable chemical properties, are resistant to photo-oxidative aging, acids and alkalis, can withstand the erosion of various natural environmental factors and chemical substances, are suitable for different soil conditions such as different soils and deserts, can be used in harsh environments for a long time, and have a long service life.
Powerful lateral confinement effect: The lateral confinement and reinforcement effect of the cell's vertical surface is remarkable. After filling with loose materials such as soil, gravel, and concrete, the cell walls can exert a powerful lateral confinement effect on the fillers, effectively preventing the lateral displacement and deformation of the fillers, and enabling the structure to have higher stability and bearing capacity.
Drainage and Permeability Performance: Geocells have good permeability, allowing rainwater to freely penetrate inside and outside the cells. This avoids the damage to the engineering structure caused by the water pressure generated by water accumulation, helps maintain the natural moisture balance of the soil, promotes vegetation growth. At the same time, it can also quickly drain the water in the soil, preventing the soil from softening or collapsing due to water accumulation.

Product Applications:
1.Road Engineering: In the construction of highway and railway subgrades, it can be used to treat soft foundations, improve the bearing capacity of the foundation, reduce subgrade settlement, and prevent pavement deformation and cracking. In the construction of special sections such as semi - filled and semi - excavated subgrades, subgrades in sandy areas, subgrades in permafrost regions, and loess collapsible subgrades, geocells can play a unique role in effectively solving problems such as uneven settlement, frost heave, and mud pumping.
2.Hydraulic Engineering: It can be applied to projects such as dike construction and shallow - water river channel treatment. It enhances the stability and anti - scouring ability of dikes, preventing accidents such as dike landslides and dam breaches. In riverbank slope protection projects, geocells can slow down the water flow velocity, reduce the water flow energy, disperse the water flow, and reduce the erosion of the slope soil by the water flow.
3.Slope Protection Engineering: It is used in protection projects such as mountainous highway slopes, railway slopes, and riverbank dike slopes. It can fix the soil on the slope surface, prevent soil sliding and collapse, and resist the damage to the slope caused by natural factors such as rainwater scouring and weathering erosion. Combined with slope vegetation protection, it can also form an ecological, environmentally friendly, and efficient protection system, beautify the environment, and promote the restoration of the slope ecological environment.
4.Other fields: In desert governance, it can be used to fix sand dunes, prevent wind and sand erosion, and at the same time collect and store a small amount of rainwater, providing conditions for vegetation growth and improving the desert ecological environment. In projects such as airport construction, wharf construction, and mine tailings treatment, it can also play a role in strengthening the foundation and stabilizing the structure.
The selection of geocell specifications should be "guided by engineering requirements and based on geological data". Through the coordinated optimization of parameters such as materials, height, and welding distance, the goal of "technically reliable and economically reasonable" can be achieved. It is recommended to conduct on - site geological surveys before selection, and jointly formulate plans with material suppliers and design institutes. If necessary, verify the applicability of the specifications through small - scale test sections.
