Create a strong, stable surface with this 3 in. gravel grid system, designed to reinforce soft or unstable ground on slopes or flat areas. Each unit covers 151.15sq. ft. and features a 3D honeycomb structure that securely holds gravel, soil, or grass in place while reducing erosion and allowing immediate foot or vehicle traffic. Made from heavy-duty, recyclable HDPE, the grid resists aging, corrosion, and weather damage, and can be easily cut, expanded, or folded for custom installations. With the ability to support up to 1,885 PSI when filled, it evenly distributes weight while allowing water to permeate naturally. Ideal for driveways, patios, parking areas, pathways, landscaping, and shed bases, this ground grid installs quickly-just roll it out, secure it, and fill for long-lasting performance. Color: Black. Material: Plastic.
