#78 Crushed Stone in Michigan

A pole-barn project in Michigan must account for deep frost, but #78 Crushed Stone should be chosen for drainage and bedding work rather than assumed to replace all base materials. Its washed, angular chips have few fines, allowing the stone course to stay open while the pieces hold together better than rounded gravel.

Glacial sand often drains readily, yet freeze-thaw conditions can still affect work around patios, walks, and drainage lines. Place #78 Crushed Stone around drainage pipe or beneath permeable pavers when the goal is to maintain an open bedding layer. The material may be supplied under a nearby equivalent grading, so confirm what is selected before the project begins.

Permeable Paver Bedding

For paver systems that need surface water to pass through, use this stone in the setting bed and joints.

Drainage Layers

Water can move through these clean chips behind retaining walls, around foundations, and beneath walkways.

Pipe Bedding

Their small angular shape supports drain and utility pipe evenly while limiting open spaces around it.

Walkway & Patio Base

Use beneath paths, patios, and shed pads for a firm layer that drains freely after spreading and compaction.

Free Draining

With few or no fines, washed chips allow water to pass through quickly.

Stays Put

Its angular shape lets the pieces nest together, making the layer less likely to shift than rounded gravel.

Simple Hand Placement

For smaller residential spaces, the chips can be leveled with a rake or screed by hand.

Multiple Uses

A single stone type can handle drainage, bedding, and base tasks across a project.
