2. Save materials: reduce the amount of traditional stone and concrete used, and lower project costs.
3. Environmental friendliness: Support ecological greening (such as grass planting) to reduce damage to the natural environment.
4. Long term stability: significantly improving the compressive, shear, and erosion resistance of engineering structures.
5. Multifunctionality: It can be used independently or combined with other geotechnical materials such as geotextiles and geogrids.
Product Introduction:
Geocell Driveway Mat is a three-dimensional mesh structure formed by ultrasonic welding, riveting, and other processes using high-strength polyethylene (HDPE) or polypropylene (PP) sheets. The core principle is to use a honeycomb shaped three-dimensional confinement system, which significantly improves the load-bearing capacity and deformation resistance of the filling material through the lateral constraint of the cell wall and the frictional force between the filling material and the cell. The material can be folded and transported, and during construction, it is unfolded and filled with soil, concrete, etc. to form a structure with high lateral stiffness.
characteristic
1. Three dimensional reinforcement
Compared to the planar reinforcement of geogrids, geogrids provide upward support in the vertical direction, forming a three-dimensional reinforcement system and significantly improving structural stability.
2. High lateral restraint and deformation resistance
The lateral constraint of the grid wall and the frictional force of the filling material effectively suppress the lateral movement of the soil. Experiments have shown that the apparent cohesion of medium dense sand can be increased by more than 30 times.
3. Permeable and Drainage Performance
The drainage holes on the membrane can quickly drain excess water, maintain suitable soil moisture, and promote plant root growth, especially suitable for high water flow scenarios such as river slopes.
4. Flexibility and adaptability
Parameters such as grid height and welding distance can be customized to meet different engineering requirements; The grid size can be adjusted, with small welding distance used for larger slopes and large welding distance used for smaller slopes.
5. Durability and environmental friendliness
The material is resistant to light and oxygen aging, acid and alkali, and suitable for harsh environments; Recyclable and reusable, meeting the requirements of sustainable development.

Product Applications:
1. Transportation Engineering
Roadbed reinforcement: Treatment of semi filled and semi excavated roadbeds, roadbeds in windy and sandy areas, and soft foundations, reducing uneven settlement through lateral confinement effects. For example, when building roads in desert areas, geogrids can be filled with sand and gravel locally to quickly construct stable roadbeds.
Backfill and reinforcement of the abutment: solves the problem of "bridge head jumping" at the connection between the abutment and the roadbed, and reduces differential settlement through friction.
Remediation of railway subgrade diseases: replacing traditional sand and gravel replacement methods, reducing construction difficulty and costs, and shortening the construction period.
2. Water conservancy engineering
River and embankment protection: As a revetment structure, it enhances soil erosion resistance and protects riverbank vegetation. For example, in shallow water channel management, geogrids can prevent water erosion and maintain channel stability.
Retaining walls and cofferdams: constructing flexible retaining walls, reducing the cost by more than 50% compared to concrete walls, while supporting vegetation greening.
3. Slope and geological hazard prevention and control
Slope protection: Install geogrids on the slopes of highways and railways, fill them with soil, and plant grass and shrubs to form ecological slope protection, alleviate water flow velocity, and prevent slope runoff.
Landslide control: By using the three-dimensional confinement effect of the grid, the stability of the slope is improved and the risk of landslides is reduced.
4. Engineering under special geological conditions
Permafrost areas: Ensure the minimum filling height to prevent embankment settlement caused by a decrease in the upper limit of the frozen layer.
Loess collapsible area: Treat collapsible loess foundation to enhance bearing capacity to meet vehicle load requirements.
Saline soil and expansive soil: Their corrosion resistance makes them suitable for reinforcing shoulders and slopes in the construction of high-grade highways.
5. Agriculture and ecological restoration
Greenhouse construction and soil improvement: improve soil structure, enhance fertility, and promote crop growth.
Wetland restoration and desert greening: filling with renewable materials, constructing vegetation growth substrates, and accelerating ecosystem restoration.
Geocell have become an indispensable material in modern geotechnical engineering due to their unique three-dimensional structure and engineering performance. They are economical, environmentally friendly, and efficient, especially suitable for reinforcement and protection needs under complex geological conditions.
