Contractors across Northern California are facing increasing pressure to build smarter, not just for structural performance, but for sustainability, long-term maintenance, and water management. Whether it’s for equipment yards, jobsite access roads, fire lanes, or commercial parking lots, TRUEGRID® geo cell pavers offer a technical and environmentally responsible alternative to traditional concrete or asphalt.
At Stevenson Supply & Tractor Co., we’re proud to offer TRUEGRID, a rugged, American-made geo cell paving system designed to stabilize soil, control runoff, and handle the demands of heavy construction traffic. Let’s break down how geo cell systems work, when to specify TRUEGRID, and why they’re fast becoming the contractor’s go-to for permeable paving.
A geo cell paving system consists of a cellular structure (often made from recycled HDPE) that locks aggregate or other fill material into place. The cells distribute loads laterally across the subgrade, preventing rutting, soil displacement, or ponding.
TRUEGRID pavers feature a patented, modular honeycomb grid design with integrated connectors, making installation fast, consistent, and highly scalable. The system uses open cells filled with gravel or other permeable aggregate, offering both strength and drainage.
Factor | Asphalt/Concrete | TRUEGRID® Geo Cell |
Drainage | Requires slope and storm drains | Fully permeable, reduces runoff |
Load Bearing | High strength but cracks over time | Handles up to 8000 psi when filled |
Installation Time | Curing & compaction required | Instant use after fill & compaction |
Maintenance | Prone to cracking and patching | Minimal, no re-sealing or striping |
Environmental | Impervious, contributes to heat island | 100% recycled plastic, LEED eligible |
Contractors need systems that are more than marketing fluff, TRUEGRID delivers real-world specs:
TRUEGRID PRO PLUS™ can withstand over 8,000 psi when properly filled, making it suitable for Class 8 truck traffic, forklifts, and tracked equipment.
Over 100% pervious surface when filled with clean ¾” aggregate, TRUEGRID eliminates the need for stormwater detention in many cases.
TRUEGRID pavers install at a rate of 1000–1500 square feet per man-hour, and can be compacted with standard plate compactors or drum rollers.
Unlike asphalt, which softens above 140°F, TRUEGRID remains stable from -58°F to 194°F, ideal for NorCal’s seasonal extremes.
UV-resistant and resistant to degradation from fuels, de-icers, and solvents, TRUEGRID doesn’t chip, spall, or buckle under pressure.
TRUEGRID doesn’t cut corners, and neither should you. For optimal load capacity and longevity, follow this 3-layer system:
Install edge restraints (concrete curbs, steel edging, or heavy timber) to maintain shape over time, especially in high-turn or soft-soil areas.
TRUEGRID isn’t just tough, it’s part of your SWPPP compliance toolbox.
This makes it ideal for sites under erosion control regulations, especially near wetlands, drainage courses, or sensitive habitat.

One of our general contractor clients in Napa County needed a durable parking solution for equipment trailers, while maintaining stormwater compliance for county permits. They installed TRUEGRID PRO PLUS™ over 8” of compacted Class II base with ¾” crushed drain rock fill. The result?
The entire install took just two days with a crew of four.
TRUEGRID pavers aren’t just a green solution, they’re a contractor-grade system engineered for high traffic, rapid installs, and long-term results. Whether you’re bidding a municipal site or upgrading your own yard, geo cell systems are the future of heavy-duty permeable paving, and TRUEGRID leads the way.
