#78 Crushed Stone in Maryland

Choosing this stone for a tightly packed finish is a common mistake. #78 Crushed Stone consists of washed, angular chips with very few fines, so it leaves open spaces within the material rather than forming a closed surface. That makes it a fit for drainage-related work and permeable paver bedding.

Piedmont clay can hold moisture near a patio or walk, while Eastern Shore sand behaves differently beneath the same project. Keep #78 Crushed Stone in its intended drainage role, such as bedding beneath permeable pavers, instead of substituting it for a fine material meant to close and level a surface. Material names and grading can vary, so confirm the exact stone supplied for the job.

Permeable Paver Bedding

Use it as bedding and joint fill in permeable paver installations, allowing water to pass through the paved surface.

Drainage Layers

Place these clean chips behind retaining walls, beside foundations, or below walkways to promote water flow.

Pipe Bedding

Its small angular stone settles around drain and utility pipe, offering support while limiting open gaps.

Walkway & Patio Base

For paths, patios, and shed pads, it forms a compactable base that lets water pass through.

Free Draining

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

Angular Hold

Its sharp-edged pieces press together, helping the stone layer resist shifting compared with rounded gravel.

Simple Hand Work

You can level these small chips with a rake or screed by hand on compact residential sites.

Multiple Uses

Use this material for drainage, bedding, and base tasks within a single project.
