The present invention relates to a settable material aligning arrangement that allows for settable material to be aligned to a desired level before the settable material sets. It can be used for ensuring that a poured concrete floor or shotcreted wall is levelled accurately. The settable material aligning arrangement is fixed to a support base and includes a base arrangement and an aligning formation that can be fixed at varying distances from each other by a coupling arrangement.
