Gravel Weight Verification Checklist

🕒 Last updated: June 18, 2026

A gravel weight verification checklist is used before procurement to confirm that the selected project shape, dimensions, layer depth, gravel type, bulk density, compaction allowance, wastage, bags, and delivery loads have been checked.

Gravel shortages often occur when compacted layer volume is ordered as loose volume, the wrong shape or depth is measured, or drainage gravel is treated like dense road base. This checklist records the assumptions behind the order quantity.

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓6 Inspection Points

✓1 Verification Categories

✓Before You Order+

Dimensions were measured on site.
Depth was confirmed against the intended application.
Compaction is included for bases and set to 0% for drainage gravel.
French drain gravel is single-size and open graded.
Roof ballast has structural engineer approval.
The final quantity with wastage is used for purchase.

Inspection Notes+

Confirm that rectangle, circle, L-shape, triangle, or direct-volume mode matches the measured area.

Record finished layer depth and apply compaction only to materials intended to be compacted.

Confirm supplier terminology, vehicle payload, bag size, delivery charges, and final quantity with wastage.

Common Mistakes+

Applying Compaction to Drainage Gravel

Open-graded drainage gravel relies on void space for water movement and normally uses no compaction allowance.

Ordering Finished Volume for a Compacted Base

Driveway and road-base layers need additional loose material before compaction. Use the specified compaction allowance.

Using the Wrong Shape or Layer Depth

Circular, triangular, and L-shaped areas require different geometry. Verify the selected shape and measure depth at representative locations.

FAQ

Verify it after measuring the project geometry and again before ordering whenever the gravel type, layer depth, compaction, bag size, or truck capacity changes.

No. Dense road base and driveway sub-base normally require compaction, while single-size drainage or decorative gravel may use zero or only light compaction.

No. It verifies quantity and ordering assumptions. Required layer thickness, bearing capacity, drainage design, and structural suitability must follow the project specification.
