Grass Porous Paving
Our Grasspave2 system combines structural integrity with natural aesthetics, creating durable green surfaces that handle heavy vehicle traffic while maintaining permeability. The lightweight, roll-out design allows rapid installation with 92% void space for root development and stormwater infiltration. Ideal for fire lanes, parking areas, and erosion-prone slopes, this solution reduces CO2 emissions through bioremediation while meeting strict environmental regulations.
Stormwater Storage
Rainstore3 modular units create efficient subsurface water management systems with 94% void space and no gravel requirements. These stackable, preassembled units handle depths from 4 inches to 8 feet, supporting parking areas and building foundations while providing 25 gallons of storage per unit. Certified for H-20 loading, they meet demanding urban stormwater detention and harvesting needs with LEED-compliant sustainability.
Erosion Control
Slopetame3's interlocking grid system permanently stabilizes slopes up to 45 degrees using UV-resistant recycled plastic with integrated geotextile fabric. This lightweight solution supports pedestrian and light vehicle traffic while enabling vegetation growth for natural erosion control. Duckbill anchors ensure secure installation in steep slope applications, stormwater trenches, and bank stabilization projects requiring long-term durability.
Gravel Porous Paving
Gravelpave2's high-strength plastic matrix maintains gravel stability while allowing complete water infiltration, with 5X concrete's compressive strength supporting all vehicle types. Available in five colors including UV-stable Granite, this modular system features permanent filter fabric that prevents weed growth and rutting. Ideal for fire lanes, event spaces, and ADA-compliant pathways requiring low-maintenance, sustainable surfacing solutions.
Accessible Walkways
Beachrings2 ADA-compliant mats provide temporary or permanent access across challenging terrain like sand, mud, and snow. The slip-resistant surface remains cooler than surrounding environment while supporting wheelchairs and strollers. Interlocking design allows customizable walkway lengths, with lightweight, easy-clean construction that's 100% recyclable and UV-resistant for long-term outdoor use in recreational and emergency access applications.
