Put #78 Crushed Stone where a landscape or paving detail needs a clean stone layer that does not close up with fine material. The chips are crushed and angular, while washing removes most of the dust-sized content. That leaves spaces through the layer, a useful trait for wet ground west of the Cascades where water can sit above glacial hardpan.
For drainage work, use it as bedding around pipe after the route for the drain has been established. It also fits beneath permeable pavers and in walkway or patio base work. On the Olympic Peninsula, around Puget Sound, or in other rainy settings, this material belongs in the part of the installation intended to pass moisture, not in a tightly packed driving surface. East of the mountains, the same open structure can serve paving and drainage details where winter freezing is a consideration.

Common Uses
Permeable Paver Bedding
Use beneath and between permeable pavers to leave an open route for water through the finished surface, a useful detail where Puget Sound rain meets hardpan.
Drainage Layers
Placed below walkways or beside foundations and retaining walls, these clean chips maintain open paths for water.
Pipe Bedding
These small, angular chips form a consistent bed around utility and drain pipe, supporting the pipe while reducing empty spaces.
Walkway & Patio Base
Use it beneath paths, patios, and shed pads for a stable layer that drains rather than holding water.
Why Choose #78 Crushed Stone
Free Draining
The washed chip contains little to no fine material, allowing water to travel through it quickly.
Locks in Place
Compared with rounded gravel, the angular particles fit together more securely and help keep the layer in position.
Hand Placement
Small chips can be placed and leveled by hand with a rake or screed in confined residential areas.
Versatile Stone
Use it for drainage, bedding, and base work within a single project.
