Smooth geocell， Smooth geogrid is a three-dimensional honeycomb structure made of high-density polyethylene (HDPE) material welded by ultrasonic technology. This material can be flexibly folded and unfolded at transportation and construction sites to form a mesh structure, which can be filled with soil, particles, cement, or other on-site filling materials. Smooth geocell is widely used in various engineering requirements due to its smooth surface and strong lateral and vertical constraints.

1.Load Distribution and Soil Stabilization
Load-bearing capacity: Geocells, especially those made from HDPE, distribute the weight of traffic loads more evenly across the surface, reducing stress on the underlying soil and preventing deformation or rutting of the road. The 5mm thickness provides an optimal balance of strength and flexibility.
2.Prevent soil erosion: The geocell structure helps confine and stabilize the infill material, preventing erosion due to water runoff and traffic pressure.
3.Improved Structural Integrity
Soil reinforcement: By confining the granular material within the geocell cells, the structure prevents lateral movement of the infill material, which improves the structural integrity of the roadbed and foundation.
Enhancement of subgrade performance: When installed over weak or expansive soil, HDPE smooth geocells provide a stable foundation by improving the subgrade performance, reducing settling and minimizing cracking.
Cost-Effective Solution
4.Reduces material use: By effectively stabilizing and reinforcing the soil, geocells reduce the need for expensive materials such as thick gravel or concrete. This makes the overall road construction more cost-effective.
Quick installation: The geocells are easy to install, reducing construction time and labor costs. Once unrolled and filled with infill material, the geocell structure is ready to function immediately.
Long-term Durability
5.Weather-resistant: HDPE is highly resistant to UV radiation, chemicals, and temperature extremes. This makes 5mm HDPE smooth geocells highly durable and suitable for long-term use in all weather conditions.
6.Maintenance-free: Geocell structures generally require minimal maintenance once installed, as they are robust and resistant to the wear and tear of heavy traffic and environmental factors.
Application Areas；
1.Road Base Reinforcement；One of the most common applications of 5mm HDPE smooth geocells is for reinforcing the road base. It can be used to stabilize subgrade soils that have low load-bearing capacity, especially in areas with high moisture content or soft soils.
2.Geocells are commonly employed in:Access roads/Sub-base reinforcement/Heavy traffic roads where high load-bearing capacity is necessary.
3.Slope Protection and Embankments；The smooth HDPE geocell structure can also be used in road embankments and slopes. By stabilizing the embankment material, the geocell prevents soil erosion, reduces slippage, and increases the lifespan of the slope.
4.Steep slopes: In areas where roads are built on hillsides or steep gradients, geocells help prevent erosion and landslides.
Bank protection: Geocells protect the slopes from erosion caused by runoff water or wind.
5.Drainage Systems；Geocells help in creating drainage systems by improving the permeability of the roadbed. This is especially important in roads built in areas prone to heavy rainfall or flooding. The 5mm thickness and smooth surface allow for the proper flow of water through the geocell structure, while still stabilizing the ground underneath.
6.Temporary Roads or Construction Sites；In temporary roads or construction sites, where quick and cost-effective reinforcement is required, HDPE geocells are an excellent choice. They can easily be installed and removed, and provide the necessary stability and load-bearing capacity for construction machinery and heavy vehicles.

Geotechnical materials refer to various materials used in civil engineering to improve soil properties, enhance structural stability, isolate, drain, and prevent seepage. They are usually made of synthetic fibers, polymers, and other materials, and are widely used in infrastructure construction such as roads, railways, water conservancy, environmental protection, and landfills.
The service life of geotechnical materials usually depends on the type, quality, construction method, and application environment of the material. Generally speaking: The service life of geotextiles varies from 10 to 30 years, and if exposed to strong ultraviolet radiation and harsh weather conditions, the service life will be relatively short. The service life of geomembrane is relatively long, generally up to 20-50 years, especially HDPE geomembrane, which has a relatively long anti-aging ability in a good environment. The service life of geogrids and geonets is usually between 20-30 years, depending on the corrosiveness of the application environment.
When selecting geotechnical materials, the following factors need to be considered: Project requirements: such as whether anti-seepage, reinforcement, filtration, or drainage functions are needed. Soil and environmental conditions: such as soil type, humidity, temperature, chemical corrosiveness, etc. Design parameters: such as strength, permeability, aging resistance, etc. Construction conditions: including laying thickness, construction method, etc. After understanding the specific application scenarios, the most suitable material type can be determined through communication with material suppliers or professional engineers.
Geotextiles: Used for functions such as separation, reinforcement, filtration, and drainage. Geomembranes: Used for anti-seepage, commonly used in anti-seepage projects such as landfills and reservoirs. Geogrids: used to reinforce soil, enhance the stability of roadbeds and foundations. Geonets: mainly used for drainage and soil reinforcement. Geobags: commonly used for river management and slope protection. Geosomposites: composed of multiple layers of geosynthetic materials with different functions, possessing multiple functionalities, such as composite geomembranes.
Roads and railways: Used to reinforce soil, improve roadbed stability, and prevent settlement, commonly used materials include geotextiles and geogrids. Water conservancy engineering: used for anti-seepage, drainage, reinforcement of dams, river treatment, etc. Common materials include geomembranes, geotextiles, geogrids, etc. Landfill site: used for anti-seepage and isolation to prevent leachate from polluting groundwater. Commonly used materials are geomembranes and geotextiles.

Ecological restoration and landscape construction: used to prevent soil erosion, stabilize soil, and promote vegetation growth, commonly using geotextiles, geonets, etc.
What are the construction precautions for geotechnical materials? Avoid damage: During the construction process, geotechnical materials should be protected from mechanical damage or excessive stretching. Material laying: Ensure even and wrinkle free laying, avoid incomplete or uneven coverage. Seam treatment: Use appropriate welding or bonding methods where seams are needed to ensure good sealing of the seams. UV protection: If the material is exposed to sunlight for a long time, it may degrade due to UV radiation. Measures need to be taken to protect the materials, such as using coverings or adding anti UV agents.
