About Us

Wagners Precast Concrete, formerly Dowstress, is a wholly owned subsidiary of the Wagner Group of Companies. The Dowstress business has been in operation as a precast and prestressed concrete operation for over forty five years at its current location in Wacol and under current ownership of Wagners for over eleven years.


Our location in Wacol gives easy access to the Ipswich Motorway and connections to other major arterials and access to other Wagner sites regionally.

We have also manufactured a range of client specified precast concrete elements including post tensioned water reservoir panels, concrete batch plant bins, dam wall face panels and fish way structures.
