#57 Stone in New Hampshire

Number 57 stone is one of the most widely specified aggregate products in the construction industry. Designated by the American Society for Testing and Materials (ASTM), #57 stone consists of angular crushed rock pieces sized between 3/4 inch and 1 inch in diameter. This precise gradation makes it the standard choice for concrete aggregate, drainage systems, and a wide variety of structural and landscaping applications where consistent sizing and reliable performance are essential.

The popularity of #57 stone stems from its ideal balance of size and function. Large enough to provide excellent drainage and void space, yet small enough to work easily in concrete mixes and fit tightly in confined areas, this aggregate handles virtually any task thrown at it. When used in drainage applications, the uniform sizing creates consistent channels for water flow, preventing clogging and ensuring long-term performance. In concrete production, #57 stone provides the structural backbone that gives the finished product its compressive strength.

Contractors rely on #57 stone for its predictability and proven track record. Whether you are pouring a concrete foundation, installing a French drain system, or building a retaining wall, #57 stone meets the engineering specifications required for these critical applications. For homeowners, it is equally valuable as a driveway surface material, decorative ground cover, or general-purpose aggregate. Bulk delivery makes it easy and economical to get the exact quantity needed for projects of any size.

Concrete Aggregate

#57 stone is one of the primary aggregates used in concrete production. Its consistent 3/4 to 1-inch sizing provides the structural framework that gives concrete its compressive strength and durability for foundations, slabs, and structural elements.

French Drains & Drainage Systems

The uniform sizing of #57 stone creates ideal water channels in French drain installations, curtain drains, and perimeter drainage systems. Water flows freely through the consistent void spaces without clogging or settling.

Retaining Wall Backfill

#57 stone is commonly specified for backfilling behind retaining walls. Its consistent sizing ensures proper drainage behind the wall while providing stable structural support that prevents hydrostatic pressure buildup.

Driveway & Parking Surfaces

As a surface material, #57 stone creates durable, well-draining driveways and parking areas. The angular pieces interlock under compaction while the slightly larger size provides excellent traction for vehicles.

Industry-Standard Sizing

#57 stone meets ASTM specifications for aggregate gradation, ensuring consistent quality and predictable performance. This standardization means you can trust it to perform as expected in engineered applications.

Superior Drainage

The uniform 3/4 to 1-inch sizing creates consistent void spaces that promote excellent water flow. This makes #57 stone one of the most effective drainage aggregates available for both residential and commercial applications.

Structural Strength

As a concrete aggregate and base material, #57 stone provides the structural backbone that supports heavy loads and resists settling. Its angular shape interlocks under compaction for maximum stability.

Multi-Purpose Value

From concrete mixing to drainage to decorative landscaping, #57 stone handles a remarkably wide range of applications. This versatility means fewer material types to order and manage on multi-phase projects.
