Porous Paver Systems: Engineered Load Support & Stormwater Management
Sustainable Infrastructure Solutions Since 1982
If your project demands elite load support and permanent surface stabilization—from high-traffic fire lanes to sensitive resort trails—the choice of system is critical. Rigid Porous Paver systems, pioneered by Presto Geosystems, represent the highest standard in Low Impact Development (LID).
As an industry leader for over four decades, GeoCHEM, Inc. provides the technical expertise and factory-direct inventory required for mission-critical civil engineering projects where flexible "rolled" products or low-tier imitations often fail under torque.
The GeoCHEM Advantage: Rigid System Integrity
In a market saturated with lightweight fabrics and flexible "turf mats," GeoCHEM provides ORIGINAL & GENUINE rigid polyethylene technology. Manufactured in the USA, our porous pavers are engineered to maintain structural ductility across extreme temperature swings.
Unlike flexible products that can suffer from "mechanical unzipping" or torsional rutting under heavy vehicle tires, our rigid units are designed to create a consistent, high-strength footprint that performs in both southern heat and northern freeze-thaw cycles.
Engineered 3D Confinement
The GeoBlock® and GeoPave® systems utilize interlocking, high-density polyethylene (HDPE) units to create a high-stiffness structural mattress that:
-
Distributes Heavy Loads: Specifically engineered to meet AASHTO H-20 and HS-25 loading requirements, supporting vehicles up to 80,000 lbs (with a site-specific engineered base).
-
Facilitates Infiltration: Transforms paved surfaces into high-percolation zones, recharging groundwater on-site and significantly reducing or eliminating detention pond requirements.
-
Protects Root Zones: In vegetative applications, the rigid cell walls are designed to resist soil compaction, safeguarding the turf root zone even under emergency vehicle traffic.
-
Reduces Maintenance: Significantly lowers the need for constant regrading, infill replacement, and pothole repair compared to unconfined aggregate or soil.
High-Performance Product Lines
-
GeoBlock® 5150 (The Structural Standard) Grass Paver: Featuring a 2-inch (50mm) depth, the 5150 is the premier choice for heavy-duty traffic applications, including fire lanes and utility access. Its deeper cell structure allows for a larger root zone and superior load-spreading capabilities over softer subgrades.
-
GeoBlock® (The Versatile Original) Grass Paver: With a 1.2-inch (30mm) depth, the original GeoBlock is engineered for high-use pedestrian areas, golf cart paths, and overflow parking. It provides a rigid, interlocking surface that prevents soil compaction and turf damage while offering a more cost-effective profile for lighter-duty projects.
-
GeoPave® Aggregate Pavers: Features a monolithic mesh bottom for unparalleled aggregate retention. Ideal for stabilized gravel parking, ADA-compliant pathways, and utility staging.
-
GeoWeb® Cellular Confinement: The original 3D geocell for pervious soil stabilization in extreme terrain and industrial-scale load support.
Green Building & Low Impact Development (LID)
Our porous paving solutions are critical for modern green infrastructure and sustainable site design:
-
Stormwater Compliance: Significantly reduces or eliminates the need for expensive traditional drainage infrastructure (pipes, catch basins, and curbing) by allowing water to flow directly back into the ground at the source.
-
LEED® Credits: Contribute to high-level green building credits by managing stormwater quantity and quality, reducing site disturbance, and utilizing 100% recycled content.
-
Heat Island Mitigation: Provides a breathable, permeable alternative to asphalt. These surfaces stay significantly cooler and promote natural evaporation, reducing the "Heat Island" effect in urban environments.
