Brief the supplier properly
Start with material and lift depth
Clay needs kneading (padfoot, rammer); sand and crushed rock respond to vibration (plate, smooth drum). Tell the supplier your loose layer thickness.
Ask what density is specified
If a geotechnical engineer or council requires a percentage of maximum dry density, choose a machine and number of passes that can reach it and allow for testing.
Plan water
Material that is too dry or too wet will not compact properly. Confirm the water source, a water cart or a hose supply before rollers arrive.
Watch vibration near structures
Heavy vibratory rollers can damage adjoining buildings, services and retaining walls. Consider static mode or a smaller machine near sensitive structures.
For Townsville specifically, tell the supplier the exact site address so they can confirm the depot the machine will come from, the travel or float charge and any QLD permit needs.

- Hand-arm vibration and noise exposure must be managed for plate and rammer operators—rotate tasks and supply hearing protection.
- Rollers operating near edges and batters need rollover protective structures and seatbelts in use.
- WHS regulator for Townsville: Workplace Health and Safety Queensland. Oversize transport: Oversize and overmass movements are permitted through the NHVR, with Department of Transport and Main Roads consent on state roads.
