HDPE/PP Geocell

Geocell Performance Comparison

(Remarks: perforated or double-sided weave available)

Product description  

The geocell is a grid cell structure formed by strong welding of high-strength thermoplastic sheets. It can expand and contract freely, and can be collapsed during transportation, and then opened and filled with earth, stone or concrete materials during use, forming a structure with strong lateral restraint force and high rigidity. It can be used as a cushion to increase the bearing capacity of weak foundations, it can also be laid on slopes to form slope protection structures, and it can also be used to build retaining structures.

Geocells play a crucial geocells in road construction. They are used to reinforce the road base, enhancing its load-bearing capacity. This helps to prevent settlement and deformation, ensuring a more stable and durable road surface.

In road construction, geocells provide excellent confinement of the fill materials. This leads to improved strength and stiffness of the pavement, allowing it to better withstand traffic loads and environmental stresses.

The use of geocells in road construction offers benefits such as reduced construction time and costs. They are easy to install and can be filled with a variety of materials, making them a flexible and efficient solution for building strong and long-lasting roads.

Features

1. It can be stretched freely, can be collapsed during transportation, can be stretched into a net shape during construction, and filled with loose materials such as soil, gravel, concrete, etc., to form a structure with strong lateral restrictions and high rigidity;

2. The material is light, wear-resistant, stable in chemical properties, resistant to light and oxygen aging, acid and alkali resistant, suitable for different soils and deserts and other soil conditions;

3. High lateral restriction and anti-slip, anti-deformation, effectively enhance the bearing capacity of the subgrade and disperse the load;

4. Changing geocell height, welding distance and other geometric dimensions can meet different engineering needs;

5. Free expansion and contraction, small transportation volume; convenient connection and fast construction speed.

Application range

1.Provides a convenient construction technique for access on soft ground that is not adversely affected by wet weather conditions.

2.Can be filled with angular rock, concrete or vegetated soil. A stable layer is formed that protects the slope from erosion.

3.GeoCell can be installed on slopes with slopes up to 60 degrees, and on channels with flow velocities greater than 25 ft/s (7.6 m/s), depending on the fill material. Use angular rock when flow velocities are up to 10 ft/s (3 m/s), vegetated soil when flow velocities are up to 20 ft/s (6 m/s), and concrete when flow velocities are greater than 20 ft/s (6 m/s).

4.Can be used in cut and fill applications on retaining walls. The flexible HDPE panels were custom-made to the front and rear dimensions required by the project engineer. Easily installs around curves, pipes or other structures. The strips on the front of the panels are green or tan to blend in with their surroundings. GeoCell panels can be stacked to create 90-degree walls or stepped at each level to create exposed cells for vegetation to grow on.

Construction Method
1. Geomembrane laying should be carried out from top to bottom on the slope, avoiding excessive tension.

2.Adjacent longitudinal joints should not be aligned horizontally and should be staggered by at least 1 meter.

3.Longitudinal joints should be at least 1.50 meters from the dam foot and bend foot, and should be located on the same plane.

4.When laying the membrane on a slope, the direction of laying should be roughly parallel to the slope.

5.During construction, first level the base with small-particle sand or clay, then lay the geomembrane. The geomembrane should not be stretched too tight, so that the ends embedded in the soil have a corrugated shape. A transition layer of sand or clay approximately 10 cm thick should be laid on top of the geomembrane.
