CORE's flagship foundation
CORE Gravel 60-40 HDV
Heavy-duty permeable gravel stabilization for driveways, parking areas, trails, slopes, fire access lanes, and public pathways.
Proven Since 2010
Designed for stable, accessible gravel surfaces that reduce rutting, washout, gravel migration, and drainage issues. Suitable for contractors, municipalities, landscape architects, and commercial projects.
12.4sq.ft per unit
These larger units help larger projects go down fast.
The only gravel grid in its class with a non-rotting, welded geotextile backing designed for long-term stability and drainage.
Geo-textile backing
Our grids feature a welded, non-woven geotextile that will not rot and remains fully permeable. It helps suppress weeds, separates clean infill from the subbase, and prevents gravel from migrating underneath and dislodging the grids overtime (essential for slopes).
CORE Gravel 60-40 Paver Structure
One unit measures in at 45" x 39"
Each full unit can be divided into four sections, each measuring 22.7" × 19.7". Before unclipping the sections, cut the geotextile backing along the connecting joints.
Lateral Drainage
The openings between cells allow water to move freely beneath the gravel, following the natural slope and maintaining uninterrupted drainage.
Unmatched strength
Our grid system is engineered to withstand extreme loads, making it perfect for driveways, parking areas, and heavy-duty applications.
Supports heavy vehicles and equipment
Prevents ground erosion and rutting
Durable and long-lasting construction
