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!
