Cracks are often thought of as a consequence of using concrete but they can be planned for and designed out in advance. This seminar highlights how by understanding the causes of cracking and control methods, cracking can be effectively and successfully managed. The seminar details two crack control techniques post tensioning and steel fibres. A water retaining structure is the ultimate test of an anti-crack  design – we will see how the Denham Water Tank for Watercorp was designed and constructed. The CIA’s new draft guideline on cracking and crack control is presented which will prove a handy addition to the design and construct handy attention to the design and construct bookshelf, highlighting the causes and factors affecting cracking in concrete structures and overview of procedures for minimising the adverse effects of cracking.

Graeme Dundas, Technical Director, BG&E

Denham Water Tank.

This structure highlights how post-tensioning as a design technique, can be used to control cracks. This structure is an elevated water retaining tank for Water Corp constructed using post tensioning with no joints. Graeme will discuss all aspects of the design strategy to meet client requirements of 100 year design life and the construction challenges of the tank.


Dr Tian Sing Ng, Engineering Manager, BOSFA

Fibres for Crack Control

Steel fibre reinforcement is another technique which can be designed in advance to control cracks. Tian will outline how to design for limiting crack width/crack control of a conventional reinforced concrete as per current available codes and guidelines, the fundamental basis of crack control section in Australian Standards, the use of fibres in crack control and predicting the crack width.


Rodney Paull, Principal Materials Engineer and Durability Consultant, GHD.

 Z7/06 “Concrete Cracking and Crack Control”.

Rodney is the Chair of the Concrete Institute’s Durabilty committee and will discuss the Concrete Institute’s draft durability guideline to be launched later in 2017.  This is an Australia first scoop on this document and a great opportunity to review what it covers.


This document Z7/06 provides up-to-date guidance on concrete cracking and the design for crack control for Australian structures, as well as the assessment, monitoring and repair of cracks. The causes and factors affecting cracking in concrete structures are discussed and procedures for minimising the adverse effects of cracking are presented. In addition to providing reliable design guidance on the control of cracking in new structures to ensure serviceability and durability, the advice provided will also assist designers to diagnose the cause of cracks in existing structures and, where appropriate, to specify effective remedial measures.
