Perforated Geocell
1.Convenient Construction:
Geocells are lightweight and foldable, facilitating easy transportation and laying, which leads to high construction efficiency.
2.Excellent Performance:
They possess functions such as reinforcement, separation, drainage, and protection, effectively enhancing the stability and durability of engineering projects.
3.Strong Adaptability:
Different materials, specifications, and types of geocells can be selected according to various engineering requirements and environmental conditions, demonstrating strong adaptability.
4.Environmentally Friendly and Energy-Saving:
Made of high-molecular polymer materials, geocells are recyclable, cause no pollution to the environment, and meet environmental protection standards.
Product Introduction:
Perforated Geocell is a three-dimensional net-like cellular structure formed by high-strength high-molecular polymers (such as HDPE, PP, etc.) through forceful welding or riveting. It features the ability to stretch and contract freely, can be folded for transportation, and can be tensioned into a net-like shape during construction. After being filled with loose materials like soil, gravel, or concrete, it can form a structural body with strong lateral restraint and high stiffness.
Functional Characteristics：
Reinforcement: It can significantly enhance the shear strength and bearing capacity of soil, and reduce soil settlement and deformation.
Separation and Protection: It can separate soil materials or fillers with different particle sizes to prevent them from mixing with each other, thus ensuring the stable performance of materials in each layer.
Drainage: The grid structure of the geocell has a certain degree of water permeability, enabling it to quickly discharge water from the soil and improve the soil's shear strength.
Vegetation Protection: It provides favorable attachment conditions for vegetation growth, promotes vegetation development, and plays a role in soil consolidation, slope protection, and environmental beautification.

Product Applications:
1.Road Engineering：It can be used for the treatment of semi-filled and semi-excavated subgrades, subgrades in sandy areas, reinforcement of abutment backfill for subgrades, subgrades in permafrost regions, and the treatment of collapsible loess subgrades.
2.Slope Protection: Geocells can be used to reinforce slopes, preventing soil erosion and landslides.
3.Dam Engineering: They are employed to prevent issues such as dam sliding and breaching, enhancing the stability and durability of dams.
4.River Regulation: Suitable for both natural and artificial river channels, geocells can address problems such as river erosion, riverbank collapse, and severe siltation of riverbeds. They can also be used for the restoration of river and lake aquatic ecosystems, improving water quality and protecting the aquatic ecological environment.
5.Other fields: It is used for tunnel lining, track support, etc., in subway projects; in some ecological restoration projects, it can prevent soil erosion, protect vegetation growth, help maintain soil moisture, promote plant growth, and achieve the goal of ecological restoration.
As a high-performance geosynthetic material, geocell, through technological innovation and application optimization, will play a more significant role in infrastructure construction, driving the realization of the dual objectives of engineering safety and sustainable development.
