In this article, we will discuss Geocell in Road Construction.


Geocell has great potential to be employed as a cost-effective solution to various technical problems. Modem construction methods also extend the use of geocell-reinforced soil retaining walls which contain new cladding elements, reduce construction time and costs, and permit better aesthetic needs for the final structure. Generally, geocell is commonly employed in various environmental projects.


Geocells are 3D, expandable panels prepared of high-density polyethylene (HDPE), polyester, or other polymeric material. During installation, the connected strips expand to form flexible, 3D cellular structural walls where backfill materials such as sand, earth, stone, etc., are positioned and compacted.

It makes a free-drainage system that carries the filling materials and controls movement by delivering traction through tensile reinforcement. Geocells thus enhance the structural and functional behavior of soil and aggregate filling material.




  1. Different Types Of Geocell  

Geocells come in different types and specifications that solve various problems in different soil types. Geocells are mainly categorized into two types:


1. Perforated Geocell

Perforated geocells own regular holes in the cell walls that enhance stress distribution and decrease deformation. This is accomplished through a big number of edges that turn into cells. The integrity of the geocell relies on the strength of the perforated strip and weld.

The tensile strength and seam weld strength of the geocell is specified by a tensile testing machine. The weld strength of the strip must be equivalent to or greater than the tensile strength of the strip itself.

2. Non-Perforated Geo Cells  

Non-perforated Geo cells possess thick and smooth walls. It is usually a polymer sheet with a 3D mesh structure having a revetting link or ultrasonic welding.

Normally, unpaved roads are usually constructed on unstable soils, such as wide clay, peat bogs, or sand. If these roads are not constructed with suitable technology, then there is a huge chance that these materials will crumble and threaten road stability.

Geocells provide the solid stiffness and creep resistance required to reinforce soft soiLs. They control the shrinking and cracking of the clay, facilitate lateral dispersion and filtration of sandy soils, and strengthen the subsoil in all soft soils.

Road maintenance with cellular restraint systems keeps them in the right situations. Roads can have maintenance problems due to inappropriate underground needs (due to improper characteristics of subsoil), which can guide to damage, cracking, washing out, and settlement of unpaved surfaces.

By employing geocells permanent and temporary roads can be made, and their ground stability requirement can be enhanced. Geocell enhances the load-bearing capacity of granular pavements and porous surfaces employed in heavy machines, are and, at the exact time, decreases costs.

The system decreases the quantity of water on the surface and replenishes groundwater supplies. In addition, the traffic or parking lot can be covered with plants or small weeds, which is a useful solution for saving space.

No equipment is needed to expand the geocell sections, which facilitates installation because the cells can be positioned in the softest substrates, and no low-pressure equipment is needed for filling. Fully loaded dump trucks can effortlessly unload cargo and disperse granular material inside and on the geocell.

  5. Disadvantages Of Geocell In Road Construction  

The following are the disadvantages of geocells in road construction:

a. The Long-term performance of the specially formulated resin employed to make the geocell must be guaranteed by utilizing appropriate additives, including antioxidants, ultraviolet filters, and fillers.

b. Management, storage, and installation must be ensured by careful quality control and quality assurance.
