Coir Geo Cell

A Coir Geo Cell is a three-dimensional cellular confinement system made from natural coir fibre. When filled with soil or aggregate, the honeycomb structure provides all-round confinement, preventing lateral movement of the infill and creating a stable, reinforced layer that improves soil strength and erosion resistance.

The Geo Cell structure distributes loads across a wider area and reduces shear stresses within the soil. Laboratory and model-scale studies have shown that Coir Geo Cells significantly reduce soil displacement and erosion under rainfall and hydraulic loading, maintaining slope integrity where unreinforced slopes may crack or slip.

Yes. Testing under simulated rainfall conditions has demonstrated that slopes reinforced with Coir Geo Cells retain cohesion even during high-intensity rainfall. The confined soil layer resists surface run-off and sheet flow, while the cellular structure helps retain moisture and supports vegetation growth.

Yes. Research indicates that smaller Geo Cell sizes generally provide greater confinement efficiency, increased stiffness and reduced soil displacement compared to larger cells. Cell size selection should be based on slope gradient, loading conditions and project requirements.

Analytical modelling shows that a Coir Geo Cell layer behaves like a flexible reinforced slab. It mobilises tensile, bending and membrane actions, redistributing stresses within the soil mass and reducing deformation compared to conventional two-dimensional reinforcement systems.

Yes. Experimental shake-table testing in saturated sandy soils has shown that Coir Geo Cell reinforcement reduces excess pore-water pressure generation and improves liquefaction resistance. Full-depth Geo Cell configurations provided the greatest improvement by limiting lateral soil movement and enhancing particle interlocking.

Coir Geo Cells are manufactured from natural coconut fibre, making them biodegradable and environmentally compatible. They support vegetation growth, improve soil health and provide a low-carbon alternative to synthetic reinforcement systems, making them well suited to environmentally sensitive and sustainable infrastructure projects.

Common applications include slope and embankment stabilisation, erosion control, road bases, access tracks, coastal protection works, drainage channels and green infrastructure projects where both structural performance and environmental outcomes are important.

Coir Geo Cells are designed to provide structural support during the critical early stages of soil stabilisation and vegetation establishment. Over time, as vegetation takes hold and root systems develop, the reinforced soil mass becomes increasingly self-supporting.

Yes. Coir Geo Cells work particularly well when used with vegetative cover. The cellular structure creates micro-climate zones that retain moisture, protect seeds and encourage root development, resulting in improved long-term erosion control and slope stability.
