Maintaining roadsides in proper technical condition is a key aspect of safety and durability of public roads. Ecogrid offers a modern solution to the problem of rutting and degradation of asphalt edges caused by heavy vehicles, reducing the costs of ongoing road infrastructure maintenance.
- Edge stabilization: Installing the grids at the interface between the bituminous pavement and the soil roadside absorbs the impact energy and prevents asphalt edge chipping.
- Resistance to shear forces: The cells prevent the aggregate of the roadside from being spread by vehicle tires, keeping the fill material in place.
- Permeability: Water flowing off the profiled roadway freely infiltrates into the ground through the grids, eliminating the risk of water pooling and aquaplaning.
Implementation example: The modernization of a provincial road with high transit traffic, where standard crushed stone shoulders required constant leveling. The application of the grid system on a 1-meter-wide strip reduced roadside maintenance costs by 80% over 5 years.
Key investment benefits:
- Extended lifespan of the bituminous pavement thanks to protection of its lateral edges.
- Dramatic reduction in financial outlays for regular replenishment and profiling of roadsides.
- Increased safety for road users through a stable surface in case of an emergency pull-off.
Recommended models for this application: The requirements of road infrastructure are best met by models with the highest load-bearing index and resistance to dynamic loads: Hydrogravel and the grid from the PRO series.

The system installed according to best practice (where the top of the grid is flush with the asphalt level or slightly below) is safe. A plow striking it does not cause the modules to be pulled out.
Recycled polyethylene (HDPE/LDPE) is completely chemically inert, guaranteeing resistance to sodium chloride (road salt) and petroleum-derived substances.
