Cracking in reinforced concrete structures is inevitable. Cracks occur wherever and whenever the tensile stress in the concrete exceeds the tensile strength of the concrete. This can occur because of the design, supply, construction, and the project management processes.

Michael examines the influence on cracking by the Structural Designer, Contractor, Concrete Placer / Finisher and Supplier.

Should it go wrong and end up in court, who is liable?
