Everything You Need to Know About #57 Stone
Size and Grading
- Size
- 3/16 inch to 1 inch
- Grading
- #57
- Type
- Angular crushed rock
Beneath shallow topsoil west of the Cascades, glacial hardpan can hold rainfall close to a drive or shop pad. #57 Stone is useful where a drainage system needs room for water to move through the stone rather than remain at the work area. It is also suited to concrete placements that use crushed aggregate. Conditions east of the mountains can be drier and frozen during winter, so site drainage should follow the ground actually present.
For a pipe drain through hardpan near Puget Sound or on the Olympic Peninsula, install #57 Stone around the pipe route so the drainage material can collect water from the surrounding area. Plan the outlet before covering the run. A draining stone layer helps only when the system has a path that carries collected water beyond the hardpan.

Common Uses
Concrete Aggregate
Concrete commonly uses #57 stone as a main aggregate. The 3/16 to 1-inch material forms a load-bearing stone matrix in foundations, slabs, and structural concrete, helping it carry compressive loads over time.
French Drains & Drainage Systems
For French drains, curtain drains, and perimeter systems, #57 stone forms open spaces between particles. Those spaces move water through the drain and help limit clogging or settlement, which is useful where water sits above hardpan.
Retaining Wall Backfill
Place #57 stone behind a retaining wall as backfill that lets water move away from the wall. The graded stone also forms a supporting layer and helps avoid hydrostatic pressure buildup.
Driveway & Parking Surfaces
Used as a finish layer, #57 stone provides a draining surface for driveways and parking areas. Compaction locks its angular pieces together, while the larger stone helps tires maintain traction.
Why Choose #57 Stone
Consistent Stone Size
#57 stone has a controlled range of particle sizes for predictable placement. Review your project requirements before using it in engineered work.
Superior Drainage
#57 stone in the 3/16 to 1-inch range leaves connected openings between the pieces for water movement. It can be used for drainage at residential and commercial sites.
Structural Strength
In concrete and base courses, #57 stone supports load distribution and helps limit settlement. Its angular particles lock together when compacted to create a stable base.
Multi-Purpose Value
#57 stone serves concrete mixes, drainage work, and decorative landscape areas. One material can cover several phases of a project.
