A decision you can check
- 01
State the application
Describe driveway base, decorative path, drainage trench or another use so the supplier can discuss a suitable locally available product.
- 02
Record gradation and cleanliness
Write the quarry designation, size range and whether fines or washing are required. Photograph the selected sample.
- 03
Convert with supplier data
Use calculated compacted volume and the supplier's bulk density or ordering factor to obtain tons. Round to delivery increments.
- 04
Approve the dump plan
Confirm truck size, overhead clearance, pavement limits, turnaround, pile location and responsibility if the driver cannot safely access the requested point.
Write a specification someone else can check
Mass on a weigh ticket confirms delivered weight, not installed depth or compaction.
Moisture changes bulk behaviour and can influence a volume-to-weight estimate.
- State the application
- Record gradation and cleanliness
- Convert with supplier data
- Approve the dump plan
Convert the decision into quantities
Enter the measured geometry in the Gravel Calculator, replace defaults with the selected product coverage and round only at the final purchasable unit. List accessories and preparation materials separately so a coverage change does not silently scale unrelated items.
Do not direct a heavy truck across septic systems, weak slabs, soft lawns or unverified structures.
Verify at order and delivery
Check the exact local designation or product code, performance class, size, colour or batch where relevant, stated coverage, yield, density or capacity, ordered quantity and accessory compatibility on the written order. Inspect delivered aggregate surface before installation and isolate damaged or mismatched material while return and replacement options remain open.
What usually throws the order off
- Ordering by a generic gravel name
- Assuming every crushed stone drains the same
- Using a universal density after choosing a quarry product
- Selecting a dump point without truck access
Frequently asked questions
What must the aggregate surface specification identify?
Make the scope checkable against these decisions: state the application; record gradation and cleanliness; convert with supplier data; approve the dump plan. Record the exact local designation or product, performance class, dimensions, finish where relevant, accessories and controlling technical document.
Which calculator default changes after product selection?
Replace whichever default the exact aggregate surface controls—coverage, yield, density, dimensions, package quantity or capacity—while keeping the verified project geometry unchanged.
Who should approve a substitution?
The owner and responsible designer or installer should confirm in writing that the substituted aggregate surface preserves required performance, appearance, compatibility, installation method and documented supplier or project acceptance criteria.
