Geocell Retaining Walls

2. Key Benefits

✅ High Load-Bearing Capacity – Supports up to 1,000 kPa (10 t/m²)
✅ Flexible & Durable – Withstands settlement and seismic activity
✅ Eco-Friendly – Uses on-site fill materials, reducing transport costs
✅ Fast Installation – 3–5x quicker than traditional concrete walls
✅ Cost-Effective – 30–50% cheaper than gabion or concrete walls

3. Design Considerations

3.1 Material Selection

3.2 Fill Material

• Granular soil (well-graded, ≤50mm particle size)

• Recycled aggregates (crushed concrete, 20–40mm)

• Reinforced concrete (for ultra-high-strength walls)

3.3 Slope & Height Limits

• Maximum height: 15m (with proper reinforcement)

• Recommended slope: 1:0.3 (70°–90°)

4. Construction Steps

4.1 Site Preparation

✔ Clear & level the foundation
✔ Compact subgrade (95% Proctor density)
✔ Install drainage (perforated pipes + geotextile filter)

4.2 Geocell Installation

1. Anchor the base (300mm trench + backfill)

2. Expand geocells along the slope

3. Secure with spikes (every 1m²)

4. Connect panels (thermal welding or clips)

4.3 Fill Placement & Compaction

• Layer thickness: 150–200mm

• Compaction: 92–95% density (vibratory plate)

• Reinforcement options: Geogrid layers every 1–2m

4.4 Surface Protection

• Vegetation: Hydroseeding or turf mats

• Armor layer: Riprap or shotcrete (for erosion control)

5. Quality Control & Testing

✔ Seam strength tests (peel & shear)
✔ In-place density checks (nuclear gauge)
✔ Slope alignment verification (laser scanning)

6. Applications

• Highway embankments

• Landslide stabilization

• Bridge abutments

• Coastal erosion barriers
