Bank Run Gravel

Definition

Bank run gravel is a type of naturally occurring gravel excavated directly from a gravel pit. It typically contains a mixture of particles ranging in size from ¼ inch minimum to 6 inches maximum. This material is generally used in construction and landscaping without further processing.

Purpose

The primary purpose of bank run gravel is to provide a versatile and cost-effective material for various construction and landscaping applications. Its mixed particle sizes make it suitable for use as a base material for roads, driveways, and foundations, as well as for backfill and drainage projects.

Examples of Use

1. Road Construction: Bank run gravel is commonly used as a base layer for road construction, providing stability and support for the subsequent layers of pavement.
2. Driveways: It is often used in residential and commercial driveways as a durable and stable foundation material.
3. Foundations: Bank run gravel can be used as a base material for building foundations, helping to ensure proper drainage and support.
4. Drainage Projects: Its varied particle sizes make bank run gravel suitable for drainage applications, such as around pipes and in French drains, to facilitate water movement and prevent erosion.
5. Landscaping: In landscaping, bank run gravel is used for paths, garden beds, and other features where a natural, unprocessed appearance is desired.

Related Terms

• Processed Gravel: Gravel that has been screened and sorted into specific sizes for uniformity and consistency, often used for more precise construction applications.
• Crushed Stone: Stone that has been mechanically broken down into small pieces, typically with more angular edges, used for similar purposes as bank run gravel but with different properties.
• Aggregate: A broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, and recycled concrete.
• Subbase: The layer of material, often gravel or crushed stone, placed beneath the base course in road and pavement construction to provide additional support and drainage.

Notes

• Cost-Effective: Bank run gravel is often more cost-effective than processed materials due to its natural state and minimal processing requirements.
• Variation in Quality: The quality and composition of bank run gravel can vary significantly depending on the source, so it is important to ensure that it meets the specific requirements of the project.
• Compaction: Proper compaction of bank run gravel is essential to achieve a stable and durable base, particularly in load-bearing applications such as roads and driveways.
• Environmental Considerations: Using locally sourced bank run gravel can reduce transportation costs and environmental impact, making it a more sustainable choice for construction projects.
