A honeycomb three-dimensional confinement system that can significantly improve the performance of common filler materials in load bearing and insect erosion control applications over a wide range.

Geocell Definition

Geocell is a three-dimensional mesh cell structure formed by high-strength welding of reinforced HDPE sheet material. Generally, it is welded by an ultrasonic needle. Due to engineering needs, some holes are punched into the diaphragm. Also named”geo web” or “geocell ground grid”.



Geocell Characteristics

1. The geocell is flexible and can be retracted for transportation. It can be stretched into a mesh during construction and filled with loose materials such as soil, gravel, and concrete to form a structure with strong lateral restraint and high rigidity.
2. The geocell is light in the material, wear-resistant, stable in chemical properties, resistant to light and oxygen aging, acid, and alkali, and is suitable for soil conditions such as different soils and deserts.
3. The geocell has a high lateral limit and anti-slip, and anti-deformation, and effectively enhances the bearing capacity of the roadbed and disperses the load.
4. Changing the geocell height, welding distance and other geometric dimensions can meet different engineering needs.
5. The geocell can be expanded and contracted freely, and the transportation volume is small; the connection is convenient and the construction speed is fast.

Geocell Engineering Application

1. Treatment of semi-filled and semi-excavated subgrades
When building an embankment on a slope whose natural slope is steeper than 1:5, the base of the embankment should be dug with steps, and the width of the steps should not be less than 1M. When excavating steps, the width of high-grade highway steps is generally 2M. Geocells are laid on the level surface of each layer of steps, and the geocell’s own façade reinforcement effect is used to better solve the problem of uneven subsidence.
2. Subgrade in a sandy area
The subgrade in the sandy area should be mainly low embankment, and the filling height is generally not less than 0.3M. Due to the professional requirements of low subgrade and heavy load for the subgrade construction in the sandy area, the use of geocells can limit the loose filler. The guaranteed subgrade has high stiffness and strength within a limited height to withstand the load stress of large vehicles.
3. Reinforcement of backfill roadbed
The use of geocells can better achieve the purpose of reinforcement on the back of the platform. Sufficient friction can be generated between the geocells and the filler, which can effectively reduce the uneven settlement between the subgrade and the structure, and finally can effectively alleviate the “abutment jumping”. Early impact damage to the bridge deck due to “car” disease.
4. Subgrade in permafrost areas
When building fills subgrades in permafrost areas, the minimum fill height should be reached to prevent the occurrence of slurry churn or the lowering of the upper limit of the frozen layer, resulting in excessive settlement of the embankment. The unique façade reinforcement effect of the geocell and the overall confinement of the effective implementation can ensure the minimum filling height in some special sections to the greatest extent, and make the filling have high-quality strength and rigidity.
5. Loess Collapsible Subgrade Treatment
When expressways and first-class highways pass through collapsible loess and loess with good compressibility, or when the allowable bearing capacity of the foundation of a high embankment is lower than the pressure of the cooperative load of vehicles and the self-weight of the embankment, the embankment shall also be adjusted according to the bearing capacity requirements. At this time, the superiority of the geocell is undoubtedly manifested.
6. Saline soil, expansive soil
The highways, first-class highways, road shoulders, and slopes built with saline soil and expansive soil adopt reinforcement measures. The facade reinforcement effect of the cell is the most excellent of all reinforcement materials, and it has excellent corrosion resistance. It can fully meet the requirements of building high-grade highways in saline soil and expansive soil.

Geocell Price or Geocell Cost

The price of the geocell is determined by the finished sheet thickness, sheet strength, sheet height, and welding point distance. The price of the commonly used geocell finished products is affected by many factors, and customers need to provide specific design indicators to calculate.
We calculate the geocell price based on the geocell per square meter, and the area is calculated based on the length × width of each finished product.
Geocell price factors:
1: Sheet thickness, the thickness is usually 1 mm, 1.1 mm, 1.4 mm, and 1.5 mm. Under the same height and welding distance, the larger the thickness, the higher the price; the smaller the thickness, the lower the price;
2: The strength of the sheet, the strength of the sheet is mainly reflected in the quality grade of the raw materials, and the price of the finished plastic pellets of the original packaging material is higher than that of the recycled material;
3: The height of the sheet, under normal circumstances, the larger the thickness of the sheet, the more expensive the price;
4: The smaller the distance between the welding points, the higher the price; the larger the distance between the welding points, the lower the price.

Geocell Components

The geocell is a mesh-like cell structure formed by strong welding or riveting of high-strength HDPE or PP copolymer broadband. It can be stretched and retracted freely, can be folded when transported, opened, and filled with earth, stone, or concrete when in use, forming a structure with strong lateral restraint and high rigidity. It can be used as a cushion to deal with weak foundations to increase the bearing capacity of the foundations, it can also be laid on the slope to form a slope protection geocell structure, and it can also be used to build a retaining structure.

Geocell Use

1. It is used to stabilize road, geocell driveway, and railway subgrades.
2. It is used for the management of embankments and shallow water channels that bear the load.
3. Hybrid geocell retaining wall used to prevent landslides and load gravity.
4. When encountering soft ground, the use of geocells can greatly reduce the labor intensity of construction, reduce the thickness of the roadbed, and the construction speed is fast, the performance is good, and the project cost is greatly reduced.

Geocell Precautions

Of course, even if the performance and characteristics of the geocell are much better than many previous road construction methods, there are bound to be some precautions and usage requirements. Otherwise, in all aspects of life, as long as this structure is used, all difficulties will be easily solved.
In fact, when using geocells to pave the road, it is necessary to ensure that the road surface is smooth, and the paved road surface must be cleaned thoroughly. The main reason for this step is to ensure that the force distribution is complete and uniform.
Assuming that there is a certain protrusion or depression in the layer laid in the geocell, the geocell will experience uneven stress. The force that should have been dispersed on each support surface was eventually concentrated in a single geocell, which would inevitably cause a chain reaction. Like dominoes, the entire road structure began to gradually crumble.
In addition, when using geocells, you should try to ensure the integrity of your own geocells. One or two gaps may not have much impact, and the geocells in other locations can share the force that the missing geocell needs to bear. But if it is a large area of damage, the construction team must use a new geogrid to build the road.


What is Geocell used for?
1. Geocells are used to prevent road (ground) ground collapse or cracks and keep the ground clean and beautiful.
2. The geocell is used to improve the bearing capacity of the subgrade and prolong the service life of the subgrade.
3. The geocell is suitable for various dams and roadbeds, slope protection geocell, and reinforcement of cave walls.
4. Geocells are suitable for load-bearing reinforcement of major airports, parking lots, wharf freight yards, etc.

What is Geocell material?
HDPE high-density polyethylene geocell is made of HDPE high-density polyethylene plastic, with a three-dimensional honeycomb structure appearance. It is a geotechnical material product for slope protection geocell, greening, and reinforcement. High-density polyethylene (HDPE) is one of the chemical commodities, its high toughness, plasticity, excellent chemical resistance, low water vapor permeability, very low water absorption, and ease of processing, make various densities grades. Polyethylene of high quality provides an attractive option for making a variety of products.

Can you fill Geocell with concrete?
Geocells are geosynthetics with a three-dimensional grid or honeycomb structure made of polymer strips interconnected. After laying, cells are formed between the interlaced strips to be filled with soil, gravel, and sometimes concrete. Geocells are mainly used for road base layer reinforcement or foundation reinforcement, and can also be used for erosion control projects. Therefore, it is possible to fill the geocell with concrete.

What is Geocell reinforcement?
After laying the geocell cushion, when a load is applied to the geocell filled with filler, most of the vertical force is converted into The lateral forces scattered around, because each cell is independent of each other, the lateral forces of adjacent cells are equal in magnitude and opposite in direction and cancel each other, thereby reducing the actual load of the foundation. In addition, the confinement effect of the cell has a certain control effect on the formation or development of the sliding surface of the base, so that the damage to the foundation develops to the deep layer, so the bearing capacity of the foundation can be improved.
Under the action of load, the geocell has a restraining effect on the lateral deformation of the filling in the cell, which is equivalent to increasing the lateral dynamic stress and improving the shear strength of the reinforced sand. The improvement of the shear strength of the reinforced sand cushion is explained by the Mohr-Coulomb strength theory. The unit body produces lateral deformation under the load. When it is in the critical state of failure, the stress circle is tangent to the strength envelope. The limiting effect on lateral deformation when using geocell is equivalent to increasing the critical point of failure by adding a stress increment to the element.
