Build Smarter, Not Thicker 🏗️

Ever wonder how to keep roads from rutting or driveways from sinking? It all starts with the 2020 Biaxial Geogrid.

By locking aggregate in place, this 20kN/m powerhouse creates a "mattress effect" that reinforces the ground from the inside out. It’s the go-to solution for high-traffic and heavy-load environments, including:

📍 Car Parks & Industrial Yards: Prevents surface deformation and keeps paving level under constant use.
📍 Road Construction: Ideal for permanent highways, temporary haul roads, and rural access tracks.
📍 Foundations & Working Platforms: Creates a stable base for heavy machinery and piling rigs on soft sub-soils.
📍 Retaining Walls & Embankments: Provides the internal strength needed for steep slopes and soil reinforcement.
📍 Railway Track Beds: Stabilises ballast to reduce long-term maintenance and improve safety.

The 20/20 Advantage:

✅ Increases Load-Bearing Capacity: Supports heavy vehicles on even the weakest ground.
✅ Reduces Costs: Cuts down on the amount of expensive stone/aggregate needed by allowing for thinner layers.
✅ Extends Project Life: Prevents cracking and rutting for up to 100 years.
