#geocells

Geocells are cellular confinement systems made from polymer sheets or strips that are formed into a honeycomb grid pattern and then flattened for shipment. When expanded on-site, they form three-dimensional mats that can be filled with soil, gravel, or other granular materials to serve as reinforced turf reinforcement structures. Typically made of high-density polyethylene (HDPE) or polypropylene (PP), they come in forms ranging from tubular to rectangular to hexagonal shapes.

Advantages for Erosion and Slope Protection

Geocells offer several key advantages compared to conventional erosion control methods like seeding and sodding or riprap placement. As confinement cells, they help prevent soil particles from migrating and allow vegetation to establish deep and strong root systems. The layered cellular structure also improves soil shear strength and bearing capacity. Some major benefits include:

- Increased infiltration and retention of rainfall, which assists with vegetation growth and reduces surface water runoff. The honeycomb design slows water flow across slopes.

- Reinforced soil strength from infill materials contained within each individual cell. Properly installed geocells can increase shear resistance by up to 600%.

- Accommodation of uneven subsidence and shifting of infill due to settling, without structural failure like a rigid barrier might experience.

- Support for slopes up to 1:1 or 45° gradients, allowing development of steeper slopes than typical soil conditions permit.

- Fast and easy installation process once the geocell materials arrive folded and compact on pallets. Large areas can be covered rapidly.

Common Geocell Applications in Infrastructure Projects

Given their multifaceted erosion and stability enhancements, Geocells find widespread use for protecting slopes, channels, shorelines and other vulnerable surfaces. Some prominent real-world applications include:

- Roadway and railway embankments: Strengthening cut and fill slopes along transportation corridors.

- Stormwater management: Stabilizing swales, detention ponds, spillways and outlets subject to flowing water.

- Coastal engineering: Protecting shorelines, revetments, breakwaters and jetties from wave action.

- Mining reclamation: Remediating mining spoil piles, tailing dams and containment dikes.

- Landfill development: Allowing steeper side slopes at waste containment facilities to maximize airspace.

- Land development: Enabling construction on previously unbuildable hillsides and slopes upgraded using geocells.

Selecting the Proper Geocell for Specific Site Conditions

With the variety of available geocell products, correctly matching the material and installation design to anticipated loads and performance needs is important. Key factors to consider include:

- Type and size of infill material - Smaller cell sizes for angular rocks, larger for soils.

- Subgrade strength and compressibility - Deeper cells penetrate weaker substrates.

- Drainage requirements - Ribbed, channeled or dimpled surfaces improve internal drainage.

- Settlement tolerance needs - Regular or irregular cell shapes influence flexibility.

- Erosion thresholds - Cell dimensions affect permissible flow shear stresses.

- Maintenance access - Opening dimensions impact equipment access.

- Design life expectations - Material thickness and oxidative resistance specifications.

Proper Installation Is Critical for Geocell Performance

While they are easier to put in place than hard structures, success still hinges on attention to proper subgrade preparation, installation sequences and infill compaction:

- Clear and level the foundation area of rocks and debris, and proof-roll to identify soft pockets.

- Unroll geocells across slope, securing the edge flaps and seams against slippage.

- Load infill materials in lifts no thicker than 8", compacting each with a light roller or track vehicle.

- For large fills, complete initial lifts before rolling out additional geocell layers up the slope.

- Seed or hydromulch the slope promptly after final grading to establish vegetation for long-term protection.

- Inspect periodically, especially after high rainfall events, to identify any issues requiring attention.

As sustainable solutions for erosion and infrastructure protection, they have revolutionized land development, construction, and protection of vulnerable surfaces. When properly selected and installed, they form durable reinforced structures promoting soil and vegetation retention over conventional methods. Their versatile confinement capabilities make geocells a smart choice for stabilizing slopes, channels, shorelines and other applications in both temporary and permanent installations.

Geocells are versatile and multi-functional because to their high-quality design. One of the most common applications is for structural protection. Large firms, for example, use the cells as protective linings for hydraulic structures and many types of industrial equipment.

Because of their propensity to expand, Geocells Market are highly useful for compacting materials inside. This extension creates a free-draining system that yet prevents mass movements that are impossible to prevent with other construction materials and procedures. The protection and stabilisation of steep slope surfaces is another wonderful application for the cells. In mountainous places, geocells are used not just to stabilise the ground, but also to strengthen and extend the life of roads.

Geocells are cellular confinement devices that were developed as a simple and long-lasting material for stabilising and protecting the environment. Cellular confinement methods successfully preserve the compaction of the soil, resulting in a stronger structure for both the infill and the pavement. 

The Geocells three-dimensional honeycomb shape ensures its strength and durability. This format establishes a framework for better load distribution. The cell is built of high-density polyethylene (HDPE), which is used to stabilise soil that is weak or unstable. This is due to their capacity to minimise soil particle lateral movement while vertically loading on the enclosed infill.
