Presto GEOBLOCK
Porous Pavement System for Turf and Fire Lanes
Presto GEOBLOCK stabilizes turf for fire access, parking, and green infrastructure while managing stormwater.
Nexterra's GEOBLOCK® is a high-performance porous pavement system designed to stabilize turf in demanding environments such as fire lanes, overflow parking, and green infrastructure. The GEOBLOCK and GEOBLOCK5150 systems provide exceptional load support while maintaining natural infiltration across the entire surface, ensuring stormwater remains on site instead of entering the drainage network. With an engineered base that meets HS25 load ratings, GEOBLOCK combines structural strength, long-term sustainability, and visual harmony in one refined system.
Discover the capabilities of permeable grass paving that supports the weight of modern traffic while preserving the natural look and vitality of a living landscape.
Performance Advantages of GEOBLOCK
The GEOBLOCK system distributes weight efficiently through an interconnected structure that prevents surface rutting and preserves infiltration rates. Ideal for contractors seeking durable, low-maintenance solutions, GEOBLOCK strengthens turf-covered areas while enhancing stormwater performance and site longevity.
- Engineered strength: base structure supports HS25 vehicle loading
- Stormwater smart: permeable surface promotes infiltration and limits runoff
- Green growth: topsoil infill supports healthy, resilient turf
- Versatile use: ideal for fire lanes, overflow parking, and green infrastructure projects
- Minimal maintenance: stable performance and reduced surface repair over time
Upstream and Downstream Integration
GEOBLOCK serves as a key component in complete stormwater systems. Upstream, its permeable surface captures rainfall and begins infiltration at the point of contact, significantly reducing peak flow. Downstream, it connects smoothly with bioswales, detention basins, and subsurface storage areas to ensure water continues to move, filter, and recharge naturally. This seamless integration supports regulatory compliance, improves site hydrology, and enhances overall landscape performance.
When included as part of a connected site design, GEOBLOCK brings engineering precision together with natural water balance.
Environmental Benefits
Every GEOBLOCK installation helps reduce impervious cover, protect native soil structure, and increase groundwater recharge. Its porous design filters stormwater, mitigates runoff, and supports healthy vegetation growth for greener, cooler, and more resilient landscapes. These benefits align with LEED®, Envision, and other sustainable design frameworks, helping projects achieve higher environmental performance standards.
The recyclable materials and extended lifespan of GEOBLOCK reduce long-term maintenance costs and resource use, transforming working surfaces into enduring, eco-conscious assets.
Engineered for Site Efficiency
Efficient installation and dependable performance define GEOBLOCK. Lightweight, modular panels connect quickly to form a continuous load-bearing surface that can be placed using standard construction equipment. This design simplifies logistics and ensures consistent results even across challenging site conditions. When installed over a properly engineered base, GEOBLOCK delivers reliable infiltration, rapid drainage, and exceptional stability while shortening project timelines and reducing waste.
Contractors gain both operational efficiency and long-term client satisfaction through proven performance that endures from project start to finish.
Applications That Perform
Whether you are designing fire access routes, adaptive event overflow areas, or resilient green infrastructure that must integrate stormwater performance, GEOBLOCK provides dependable strength, permeability, and lasting aesthetic value. Its compatibility with both upstream and downstream site systems enhances performance across an entire stormwater network.
Ideal applications include:
- Fire access lanes and emergency routes
- Overflow and occasional-use parking areas
- Service drives, maintenance roads, and golf course paths
- Vegetated swales and infiltration zones
