Bluestone Sandstone (3/8")

Bluestone Sandstone (3/8"): Properties, Uses, and Practical Information

Bluestone Sandstone (3/8"), also known as 3/8" Crushed Bluestone, 3/8" Bluestone Chips, or 3/8" Bluestone Aggregate, is a natural, crushed stone product. It features an angular shape and a blue-gray color, which may include tan or brown hues depending on the quarry source. The material is produced by crushing sedimentary rock, typically sandstone, to a nominal particle size of 3/8 inch. This size passes a 3/8" sieve and is retained on a #4 or #8 sieve. The product is dense, hard (Mohs scale approximately 6-7), and has good compaction properties. It is generally washed or screened to remove fines, but some dust may remain, depending on processing.

Physical and Technical Characteristics

The stone's density ranges from about 1.3 to 1.5 tons per cubic yard, varying by source. It is inert and non-reactive, with low to moderate absorption rates. Particle color may vary slightly between batches, as it is a natural product. Bluestone Sandstone (3/8") is free from organic material and debris, making it suitable for many landscaping and construction uses. The product meets ASTM C33 standards for concrete aggregate when specified. Size variation and the presence of fines may occur, typically within a 5% range.

Common Applications

Bluestone Sandstone (3/8") is used in a variety of settings. Its angular shape helps it lock in place, providing stability for surfaces. It is often used as a decorative ground cover in landscaping, for pathways and walkways, as a top layer for driveways, and for drainage applications such as French drains or pipe bedding. The material is also suitable as a base or bedding layer for pavers and flagstones, as well as a concrete aggregate where ASTM C33 standards are met. Other uses include erosion control, mulch alternatives, and as a surface for playgrounds when installed with a proper subbase and safety considerations.

• Decorative ground cover for garden beds and landscaping
• Pathways, walkways, and patios
• Driveway surfacing (top layer)
• Drainage solutions (French drains, pipe bedding)
• Base or bedding for pavers and flagstone
• Concrete aggregate (if gradation and specs are met)
• Erosion control in sloped or runoff-prone areas
• Mulch alternative for weed suppression and moisture retention

Limitations and Incorrect Applications

Bluestone Sandstone (3/8") is not intended for all uses. It should not be used as a structural base material for heavy load-bearing applications; larger stone is more appropriate in those cases. The product is not recommended for high-traffic vehicular areas unless proper compaction and a suitable subbase are provided. It is not ideal for areas where a smooth, fine-graded surface is needed, as the angular stones may shift or scatter. Bluestone Sandstone (3/8") is not suitable as a sand replacement in mortar or concrete unless it meets specific gradation requirements. Natural color variation may occur, so it is not the best choice where strict color uniformity is needed. It should not be used in areas prone to frequent flooding unless contained, and its chemical resistance in highly acidic or alkaline environments is not established.

• Not suitable as a primary structural base for heavy loads
• Not recommended for high-traffic vehicle areas without proper subbase
• Not for fine grading or perfectly smooth surfaces
• Not a sand substitute in mortar/concrete unless gradation is verified
• Color may vary; not for applications requiring exact uniformity
• May not be suitable for uncontained flood-prone areas
• Chemical resistance in extreme pH environments is unknown

Comparison to Other Aggregates

Bluestone Sandstone (3/8") differs from pea gravel, which is rounded and tends to shift more. It is harder and less reactive to acids than limestone. Compared to decomposed granite, it is larger and less likely to compact into a very firm surface. The 3/8" size gives a smoother surface than larger crushed stone, but is less suitable for heavy structural bases. As a natural stone, it is more color-consistent and may have fewer impurities than recycled concrete aggregate. Bluestone is much coarser than sand and is not suitable for applications needing fine material.

Pricing for Bluestone Sandstone (3/8") varies by location, reflecting local sourcing and delivery costs. For example, in Amawalk, NY, the price per ton is $75 with a $132 delivery fee, while in Hunlock Creek, PA, the price is $27 per ton with a $135 delivery fee.
