Treating #78 Crushed Stone as though it will form a dense pad is a common placement mistake. The material is washed, angular chip stone with few fines, so it does not have the fine content needed to make a tightly closed course. Its role is in drainage layers, around pipe, and in permeable paver, walkway, or patio bedding where the stone layer needs to remain open.
Flat prairie clay can drain slowly in Illinois, and northern freeze-thaw conditions can keep moisture in a project area. Use #78 Crushed Stone around drainage pipe or in the paving layer intended to pass moisture, rather than mixing it into a fine-filled section of the build. This keeps the material doing the job its grading supports. Local aggregate naming can differ, so #78 Crushed Stone may be provided as the closest local equivalent, with the material confirmed before delivery.

Common Uses
Permeable Paver Bedding
For permeable pavers, use this small stone in the setting bed and joints so water can filter downward through the paver surface.
Drainage Layers
For drainage through prairie clay, place clean chips along foundation edges, behind retaining walls, and below walkways.
Pipe Bedding
Set drain and utility pipe in small angular stone for even support without gaps around the line.
Walkway & Patio Base
Under patios, paths, and shed pads, this material forms a compacted layer that lets water pass through.
Why Choose #78 Crushed Stone
Free Draining
Washed chips contain little to no fines, leaving water a quick path through the layer.
Locks in Place
Angular pieces bind together instead of shifting like rounded gravel, helping the placed layer hold its position.
Easy to Spread
On confined residential sites, the small chips can be spread with a rake and leveled by hand.
One Stone, Many Jobs
Use it across a project for base layers, drainage, and bedding.
