Limitations: Grid panels from different manufacturers have different coverage areas — verify your product spec. Does not include geotextile fabric, edge restraint, or filter-fabric liner. Very soft subgrades may need a thicker base than estimated.

What to do next: Compact the base in 2–3-inch lifts. Fill the grid completely with a sharp angular gravel (pea gravel can migrate). Typical grid panel coverage is ~5 sq ft per panel — verify your product label.

Planning estimate only. Vehicle-rated grid systems vary significantly; follow the manufacturer's installation requirements.
