Black Star Sand Screenings (3/8" Minus): Material Overview

Black Star Sand Screenings (3/8" minus) is a crushed stone aggregate made mostly from black basalt, a dense volcanic rock. It consists of particles up to 3/8 inch in size, along with smaller fines. The material is well-graded, with angular, sharp-edged particles that allow for strong compaction and surface stability. Its color ranges from deep black to dark gray, and it appears nearly black when wet. Black Star Sand Screenings is known for its durability, resistance to weathering, and minimal dust content when properly processed. It is free from excessive clay, silt, or organic matter, and is typically supplied in bulk or bags for landscaping and construction use. Bulk density is typically between 100 and 110 lb/ft³, and the material is pH neutral to slightly alkaline.

Common Names and Synonyms

• Black Star Sand Screenings (3/8" minus)
• Black star screenings
• Black star sand
• Black star gravel screenings
• Black star crushed screenings

Physical Properties and Performance

Black Star Sand Screenings is composed of hard, angular crushed basalt. The particle size is 3/8 inch and smaller, with fines included to enhance compaction. This material compacts well, creating a stable and firm surface. Its structure allows for good drainage, making it suitable for applications where water must move through the base. The screenings are non-reactive and chemically stable, and they resist degradation from weather and traffic. The product is typically clean, with low moisture content at delivery, and is free from organic debris. When installed properly, it creates a smooth, level base that minimizes settlement and surface shifting.

Typical Uses and Limitations

Black Star Sand Screenings is widely used in both residential and commercial projects. It is suitable as a base or sub-base for paving, driveways, and walkways. It works well as a bedding material for pavers and flagstones, and as a drainage layer in landscaping and construction projects. Other applications include fill for trenches and retaining walls, erosion control, decorative ground cover, and use as a stable base in playgrounds and sports fields. It can also be used for road shoulder repair and as utility bedding and backfill around pipes and conduits.

• Base and sub-base for driveways, walkways, and patios
• Bedding for pavers and flagstones
• Drainage fill for retaining walls and landscaping
• Fill material for trenches and utility lines
• Erosion control and decorative ground cover
• Aggregate for certain concrete mixes (limited use)

This material should not be used where a pure sand or organic topsoil is required. It is not suitable as a finished surface for areas requiring a dust-free or soft walking environment. Excessive traffic without proper compaction or edge containment may cause displacement.

Material Specifications and Standards

Installation and Site Preparation

A well-prepared base is important for best performance. The subgrade or gravel base should be compacted before applying Black Star Sand Screenings. Install the screenings in layers no thicker than 3 to 4 inches, compacting each layer with a mechanical plate compactor or roller. Use edge restraints such as metal or plastic edging to keep the screenings contained and maintain clean boundaries. Site grading should direct water away from structures to prevent pooling, as overall drainage depends on both the material and site design.

Limitations and Misuse

Black Star Sand Screenings is not suitable for applications requiring pure sand, organic soil, or dust-free surfaces. It should not be used as a finished surface in areas where a soft or cushion-like material is needed, such as some playgrounds. Proper compaction and edge containment are necessary to prevent displacement and washout, especially on slopes or high-traffic areas. Allow for up to 5% size variation and fines in each load. The material is not certified for all specialized construction uses; check project requirements before ordering.
