6 Rock
A family tradition spanning over 60 years. Serving Cobb, Bartow, Cherokee, Floyd, Polk, Gordon and surrounding counties.
6 Rock is a fine, clean aggregate that plays a critical role in projects demanding precise material placement and high permeability. Typically sized between 3/4 inch and 1/2 inch, this stone is smaller than the widely used 57 Stone and significantly smaller than 5 Rock. Its uniform size and angular, washed nature make it a specialized material of choice for protecting utilities, backfilling trenches, and creating effective filtration layers across North Georgia and Metro Atlanta. At Kevin Westmoreland Trucking, we recognize that precision logistics are as important as the material itself, and our 60-year family tradition guarantees the reliable delivery of this essential aggregate.
The Key Function of Finer Clean Aggregate
As a “clean” stone, 6 Rock contains virtually no dirt or fines. This is its most important characteristic, allowing it to perform critical functions that larger, coarser stones cannot:
- Uniform Bedding: The smaller, uniform size of 6 Rock allows it to be spread easily and evenly, creating a consistent bedding layer for pipes and conduits. This uniformity ensures the utility line is supported across its entire length, preventing localized stress that can lead to failure.
- Superior Filtration: While highly permeable, the stone’s smaller fragments create a dense barrier that effectively filters out finer soil particles from the surrounding backfill, preventing them from contaminating drainage systems or settling around utility lines.
- Compaction Protection: When used as backfill around pipes, 6 Rock compacts neatly without the large, sharp edges of coarser aggregates that could potentially damage the utility’s surface. This cushioning effect is vital for long-term integrity.
Essential Applications for 6 Rock
Our high-capacity MACK fleet ensures that bulk loads of 6 Rock (up to 18.5 tons per trip) are delivered punctually to utility and site development projects across our service area, including Cartersville, Kennesaw, and Acworth.
Utility Trench Backfill and Bedding
The primary use for 6 Rock is as utility pipe bedding and backfill. Placed beneath and directly surrounding utility pipes (gas, water, sewer, and electrical conduits), it provides:
- Protection: Shields the piping from direct contact with sharp native soil or large, damaging rocks.
- Drainage: Creates a permeable envelope that rapidly moves groundwater away from the utility, minimizing the risk of corrosion or damage from freezing.
Drainage Filtration Layers
In sophisticated drainage systems, 6 Rock is used in layers to prevent siltation. It can be placed directly above a larger aggregate layer or inside a French drain trench to prevent fine soil from infiltrating the system, ensuring the drain remains fully functional over time.
Asphalt and Concrete Mixes
Due to its precise grading, 6 Rock is sometimes specified as an aggregate component in certain asphalt mixes or for producing specialty concrete, where a smaller, uniform stone size is required for surface finish or structural integrity.
Landscaping and Walkways
In landscaping, 6 Rock provides an excellent, neat surface for paths and decorative areas where a finer, well-draining gravel is desired.
