- Interlocking Paver Edge Restraints for Curved Pull-Out Resistance
Modular interlocking restraints with spikes and optional geogrid improve paver alignment, installation flexibility, and pull-out resistance on curves.
- Permeable Paving Structure With Stabilized Drainage Layers
Layered permeable paving uses multi-plane stabilizers and underdrains to absorb water, cut runoff, and limit freeze-thaw damage.
- Curbstone Electronic Cover With Rotatable Flush Alignment
A rotatable top cover lets a curbstone-mounted electronic unit stay flush on oblique surfaces, improving drainage while avoiding step hazards.
