PaveDrain
PaveDrain
Permeable Articulating Concrete Block Pavement System
PaveDrain combines durability and infiltration to manage stormwater in urban environments.
Nexterra's PaveDrain is an advanced permeable articulating concrete block (P-ACB) pavement system engineered to deliver exceptional load support while managing stormwater efficiently. Featuring a patented arched reservoir design, PaveDrain creates substantial on-site water storage that reduces peak flows, improves storm hydrographs, and supports regulatory compliance.
Rainwater infiltrates directly through the permeable concrete blocks, penetrating the engineered stone reservoir below to restore groundwater and limit first-flush pollutants. By replacing traditional pavements, PaveDrain transforms surfaces into multifunctional infrastructure that balances durability, sustainability, and water quality.
Engineered Hydrologic Performance
Stormwater control begins with surfaces that combine infiltration and storage capacity. PaveDrain's modular design not only captures rainfall on site but stores it within the arch-shaped chambers beneath the blocks, smoothing runoff and lessening downstream infrastructure demands. This integrated hydrologic function enhances stormwater retention, reduces erosion, and improves site resilience. Key benefits comprise:
- Patented arched reservoir for expanded stormwater storage and detention
- Direct vertical infiltration facilitating aquifer recharge and pollutant capture
- Reduced reliance on costly detention ponds or underground chambers
- Cost savings through minimized infrastructure and maintenance requirements
Robust Durability and Installation Versatility
Designed to withstand rigorous urban and industrial applications, PaveDrain offers a durable, permeable surface that supports heavy vehicular loads without rutting or settlement. The system's articulating blocks interlock for stability while allowing for efficient installation using conventional equipment or hand placement, suitable for both new construction and retrofit projects. Key structural features include:
- High-strength concrete blocks meeting ASTM C936 standards with freeze-thaw resistance
- Modular mats assembled with polyester cables, enabling flexible layout and quick deployment
- Seamless surface with enhanced skid resistance and snowplow compatibility
- Multiple design and color options including high Solar Reflectance Index (SRI) values for heat mitigation
Seamless Upstream and Downstream Integration
PaveDrain excels as a pivotal component within a comprehensive stormwater ecosystem. Upstream impervious surfaces such as rooftops, sidewalks, and traditional pavements collect runoff that is channeled into PaveDrain systems via gutters and conveyance infrastructures. This expertly engineered flow management reduces velocity and sediment load, protecting the permeable pavement's infiltration capacity.
Downstream processes extend the system's water management efficacy. PaveDrain integrates with bioswales, detention basins, infiltration trenches, and subsurface storage structures from Nexterra's full portfolio. These components work in concert to enhance pollutant removal, extend detention time, and optimize groundwater recharge. Together, they support low-impact development initiatives, reduce infrastructure strain, and maintain watershed health for sustainable site stewardship.
