A paver walk across Montana ground can handle water differently east and west of the Continental Divide. Gumbo clay can stay slick after moisture, while gravelly valley soils drain sooner, and deep frost affects both. #78 Crushed Stone provides clean, washed crushed chips with angular faces and very little fine material. The spaces between those chips suit drainage layers, pipe bedding, permeable paver work, and walk or patio bases.
Use this stone for the drainage or bedding function, not as a substitute for the supporting base layer beneath a walk or patio. That distinction matters through freeze-thaw weather, especially where clay holds moisture. Chip labels can vary by area, so the exact material offered is checked with you before delivery.

Common Uses
Permeable Paver Support
Used beneath and between permeable pavers, this stone allows water to pass directly through the finished surface.
Drainage Courses
Washed chips provide an open-draining layer behind retaining walls, beside foundations, and beneath walkways.
Pipe Bedding
Placed around drain and utility pipe, these angular chips provide consistent support while reducing open pockets.
Walkway & Patio Base
Use beneath paths, patios, and shed pads to create a stable layer that allows drainage.
Why Choose #78 Crushed Stone
Free Draining
Because the washed chips have few or no fines, water can pass readily through the layer.
Locks in Place
The stone’s angular shape meshes together more effectively than rounded gravel, helping it remain in place.
Easy to Spread
On confined residential sites, these small chips can be placed and leveled by hand with a rake or screed.
Multiple Site Uses
The same stone can serve drainage, bedding, and base applications within one project.
