Recommended uses
- For the intended layer, gradation, drainage and compaction in the project.
- To correct grade, bearing or drainage after checking slope, soil and buried services.
- For work where volume, mass, delivery access, equipment and disposal are planned together.
When to avoid this material
- Avoid organic, frozen, saturated or unprepared soil.
- Do not substitute clear stone, screenings, sand and graded aggregate without understanding their function.
- Avoid compacting in lifts that are too thick or at unsuitable moisture.
Compatibility and installation
- Separate from soil where needed with a compatible geotextile and keep drainage outlets open.
- Coordinate lift thickness, compaction equipment and final elevation.
- Confirm water will not be directed toward the foundation, a neighbour or a sensitive area.
Storage, care and service life
- Protect stockpiles from contamination and runoff; do not mix layers.
- Watch settlement, rutting, erosion and ponding after early rains and freeze-thaw cycles.
- Correct the cause of movement before simply adding another surface layer.
Common mistakes
- Ordering from area alone without calculating compacted thickness.
- Confusing loose delivered volume with volume after compaction.
- Creating an attractive surface that holds water against the house.
Alternatives to compare
- Compare excavation/rebuild, local stabilization and drainage improvement based on the cause of movement.
- The lowest delivered price may cost more if it requires greater compaction or on-site handling.
