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 and ATV 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 the authorized exclusive distributor for Presto Geosystems in the State of Alaska, 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. Unlike flexible products that suffer from "mechanical unzipping" or torsional rutting, our rigid units create a high-strength, consistent footprint that performs in both extreme heat and harsh freeze-thaw cycles.
Engineered Interlocking Load Support
The GeoBlock® and GeoPave® systems utilize interlocking, high-density polyethylene (HDPE) units to create a high-stiffness structural mattress that:
- Distributes Heavy Loads: Engineered to meet AASHTO H-20 and HS-25 requirements, supporting vehicles up to 80,000 lbs (with site-specific engineered base).
- Facilitates Infiltration: Transforms surfaces into high-percolation zones, recharging groundwater on-site and reducing detention pond requirements.
- Protects Root Zones: Rigid cell walls resist soil compaction, safeguarding the turf root zone even under heavy emergency vehicle traffic.
- Reduces Maintenance: Significantly lowers the need for constant regrading, infill replacement, and pothole repair.
High-Performance Product Lines
- GeoBlock® Grass Paver: The premier choice for heavy-duty traffic (5150 model) and high-use pedestrian areas. Its rigid structure ensures a healthy root zone and superior load-spreading.
- GeoPave® Aggregate Pavers: Features a monolithic mesh bottom for unparalleled aggregate retention. Ideal for stabilized gravel parking, ADA-compliant pathways, and utility staging.
Green Building & Low Impact Development (LID)
- Stormwater Compliance: Allows water to flow directly back into the ground at the source, eliminating expensive drainage infrastructure.
- LEED® Credits: Supports high-level green building credits by managing stormwater quantity/quality and utilizing 100% recycled content.
- Heat Island Mitigation: Provides a breathable, permeable alternative to asphalt, promoting natural evaporation and cooling urban environments.
