Overview
Engineered for the conditions beneath every journey.
Cellular confinement and filtration layers retain topsoil or aggregate on vulnerable highway slopes. The system limits surface washout, supports vegetation and can reduce dependence on heavy conventional pitching where project conditions permit.
Project value
What the system is designed to deliver.
Supports vegetation
Uses locally suitable infill
Adapts to irregular slope profiles
Park highway systems
From assessment to installation
A disciplined, project-led approach.
Map water movement
Runoff paths, slope gradient and discharge points guide the protection strategy.
Prepare and anchor
The surface and anchorage zones are prepared for stable placement of the system.
Infill and finish
Selected soil, aggregate or concrete infill completes the required surface finish.
