What Is Geocell？

A geocell is a three-dimensional, honeycomb-like geosynthetic structure made from high-density polyethylene (HDPE) strips that are ultrasonically welded together. When expanded on-site and filled with soil, gravel, or concrete, geocells form a stable confinement system that distributes loads and prevents erosion, settlement, and soil migration.

Geocells are widely used in roadbeds, slopes, retaining walls, embankments, and erosion control applications.

Key Technical Specifications:

• Material: High-Density Polyethylene (HDPE)

• Cell Height: 50–200 mm (common: 100 mm, 150 mm)

• Welding Distance: 330–1000 mm

• Tensile Strength (per strip): ≥ 10–23 kN/m

• UV and Chemical Resistance: Excellent

• Cell Size: Customizable (commonly 356×356 mm expanded)

Applications of Geocell

The Geocell is ideal for a wide range of civil engineering and construction applications. Key uses include:

Soil Stabilization: Geocells provide reinforcement to soft or loose soils by preventing soil displacement. Common applications include roadbed reinforcement, railway embankments, and airport runways.

Slope Protection: Used to stabilize sloping terrains and prevent soil erosion. It is commonly applied in hilly areas, riverbanks, coastal areas, and highway embankments.

Retaining Walls: Geocells are ideal for constructing reinforced retaining walls, particularly for areas with unstable soil or high water tables.

Load Distribution: Geocells can improve the load-bearing capacity of soil in paved roads, parking lots, military airfields, and construction sites.

Erosion Control: When applied to areas prone to erosion, the honeycomb structure of geocells anchors soil particles, reducing water runoff and improving vegetation growth.

Vegetation Establishment: Geocells provide a stable environment for vegetation roots, making them ideal for green slopes, land reclamation projects, and green roofs.

Drainage Improvement: Geocells can be used in landfill projects and drainage systems, where they help manage water flow and reduce the risk of flooding.

 

The three-dimensional honeycomb structure tightly interlocks the filling material, greatly improving the lateral restraint of the soil and forming a highly stable composite bearing layer. The retractable unit freely fits the undulating base surface, effectively absorbing the uneven settlement of the foundation and reducing the risk of cracking of the rigid structure.

 

The cell space promotes the penetration and entanglement of vegetation roots, realizes the synergy of engineering reinforcement and natural greening, and curbs the erosion of the topsoil. The modular design supports rapid deployment of anchoring, reduces the use of traditional hard slope protection materials, and significantly reduces construction energy consumption and disturbance.
