The dip to lay each layer, measured down from the top of the kerb
Uses the standard densities (or your saved ones) and the thickness of each layer. The waste allowance is shared with the Tonnage Calculator. Estimate only: confirm with your supplier.
These are the finished (compacted) levels, measured down from the top of the kerb. Tap a layer to look at it in the picture. Check against your job specification and allow for roll-down as you normally would.
How thick did you actually lay it?
Estimate only. Always confirm quantities with your supplier.
Keep each job's build up, calculations and dip sheets together
The current job fills in your dip sheet details and files your saved calculations, build up and sheets under it. All of it stays on this device.
