Proven Permeability
Our proprietary grouting sand and base mix allow high rates of water flow through the pavement surface. Runoff is naturally filtered by the ground. Our green products include:
- Proprietary permeable grouting sand
- Proprietary certified mix design
- Proprietary porous subbase
Together they result in water flow and dissipation rates greater than 40 gallons per hour!
