#78 Crushed Stone in California

A patio beside a California structure can collect wet-season runoff when the bedding course closes up with fines. #78 Crushed Stone is washed, angular chip stone that leaves room for drainage within the layer. It is suited to permeable paver bedding, walkway bases, and drainage work where a clean stone course is called for.

In the Central Valley, along the Pacific coast, or near the Sierra Nevada, site drainage needs can differ with season and ground conditions. For a permeable paver surface, set #78 Crushed Stone beneath the pavers as the open bedding layer rather than using it as a fine finishing material. Fire-safe ground-cover planning near structures is a separate consideration from choosing drainage stone. Confirm the exact local equivalent before ordering.

Permeable Paver Bedding

For permeable paver installations, use it in the bedding and joints to let water move downward through the pavers.

Drainage Layers

Place these clean chips behind retaining walls, beside foundations, or below walkways to help water travel through the layer.

Pipe Bedding

The angular chips sit uniformly around drain and utility pipe, providing support while limiting open gaps.

Walkway & Patio Base

Under paths, patios, and shed pads, it forms a compacted layer that allows water to pass through.

Free Draining

With little to no fines, washed chips allow water to move quickly through the material.

Locks in Place

Its angular shape helps the pieces grip each other more than rounded gravel does, keeping the layer settled.

Easy to Spread

You can rake and screed these small chips by hand, including on close-quarter residential work.

Uses Across a Project

Use it for drainage, bedding, or base layers on a single job.
