Nigeria loses billions of naira every year to premature road failure – potholes, rutting and collapsed embankments caused by weak soils and heavy traffic. Geogrids are a proven engineering solution that makes roads stronger, lasts longer and reduces lifetime maintenance costs.
What is a geogrid?
A geogrid is a polymer mesh with open apertures that interlock with soil and aggregate particles. This interlock creates a stiff, mechanically stabilized layer that spreads loads over a wider area, preventing the movement that leads to rutting and cracking.
Types of geogrids
- Uniaxial geogrids – high strength in one direction, ideal for retaining walls and steep slopes.
- Biaxial geogrids – equal strength in two directions, ideal for base reinforcement under roads and platforms.
- Triaxial geogrids – multi-directional stiffness for superior load distribution.
Benefits for Nigerian roads
- Reduced aggregate thickness – saving on imported stone.
- Longer pavement life and fewer repairs.
- Stable construction over soft, waterlogged subgrades.
- Faster construction and lower lifecycle cost.
Where geogrids are used
Geogrids are used in highways and access roads, car parks and hardstandings, railway formations, retaining walls and steep reinforced slopes. They are often paired with a separation geotextile for the best results.
