Fill Material (3/4″ Minus, Shale)

Fill Material - Shale, 3/4” Minus

Fill material composed of shale in a 3/4" minus size range is a versatile aggregate commonly used in construction and landscaping. Shale is a fine-grained sedimentary rock that breaks down into angular fragments, making it suitable for stable fill applications. The "3/4" minus" designation means the material includes pieces up to 3/4 inch in size, along with smaller particles and fines, which help the material compact tightly.




This specific size and composition make shale fill material ideal for backfilling, site grading, and sub-base preparation for roads, driveways, and building pads. The presence of fines allows for excellent compaction, reducing the risk of settling over time. However, because shale can be less permeable than other aggregates, it may not be the best choice for drainage-critical applications. Overall, 3/4" minus shale fill is valued for its affordability, ease of compaction, and suitability for both residential and commercial earthwork projects.
