Know what to have ready

Estimate the volume

For a rectangular pour, volume is length × width × thickness. Rock-Tuff’s calculator converts thickness from millimetres and gives an estimated cubic-metre figure.

Check the specification

Use the strength or mix stated on the project specification. Do not choose an MPa based only on a website example if structural requirements apply.

Prepare the site details

Have the delivery address, site access information, required date and the on-site contact person ready before sending your quotation request.

Plan the delivery booking

A quotation does not reserve a delivery slot. Concrete delivery booking is essential, and the applicable payment requirements must be met before delivery.
