Limestone (1/2")

1/2" Limestone (Crushed Limestone Aggregate): Product Overview

1/2" Limestone, also known as 1/2" crushed limestone, #8 limestone, 1/2" clean limestone, 1/2" stone, or 1/2" aggregate limestone, is a natural, sedimentary rock product sourced from limestone quarries. This aggregate consists of angular, crushed stone particles with a nominal size of approximately 1/2 inch (actual sizes typically range from 3/8" to 5/8", varying by supplier). The material is gray to light tan in color and is valued for its hardness, durability, and free-draining properties when washed.

1/2" Limestone is non-reactive with most construction materials, pH alkaline, and typically weighs between 2,600 and 2,800 lbs per cubic yard. Its bulk density is around 95-105 lb/ft³. This stone may be supplied as "clean" (washed with little to no fines) or unwashed (containing fines). The product is often specified by sieve analysis and may meet standards such as ASTM C33 for concrete aggregate, depending on the source and local requirements.

Key Characteristics of 1/2" Limestone

• Crushed, angular stone with nominal 1/2" particle size
• Natural gray to light tan color
• Hard, durable, and pH alkaline
• Free-draining when washed; may be available with or without fines
• Weight: approx. 2,600-2,800 lbs per cubic yard
• Non-reactive with most construction materials

Typical Applications

• Drainage systems (French drains, pipe bedding, septic leach fields)
• Concrete aggregate (if ASTM C33 compliant)
• Driveways, walkways, and patios (top layer or base)
• Landscaping and decorative ground cover
• Backfill for retaining walls and erosion control
• Base material for pavers and slabs

Technical Specifications

Limitations and Not Recommended Uses

1/2" Limestone is not suitable for all applications. It is not recommended as a surface for playgrounds or barefoot areas due to its angular and abrasive nature. This material is not suitable for high-traffic surfaces without compaction or a binding agent, as loose stone may shift under repeated use. It should not be used in asphalt mixes unless specified by the mix design, or where a smooth, compacted surface is required, such as finished concrete or fine grading. The alkaline nature of limestone makes it unsuitable for acid-sensitive environments and for aquariums or aquatic environments requiring neutral pH, as it may raise water pH.

Installation and Handling Information

For best results, prepare the installation area by removing organic material and compacting the soil. When used as a base or subbase, layer and compact the stone in lifts to achieve optimal density and strength. For drainage, avoid mixing soil with the limestone to maintain permeability. Always grade the installation area to direct water away from structures. Material can be supplied as washed (clean) or unwashed (with fines), depending on drainage needs.
