Long and narrow concrete slabs and reinstatements tend to crack more than square ones. Mitigation of this risk typically includes the use of a mesh in the upper part of the slab. Reinstatement mesh is preferred to bar reinforcement for ease of installation.
Where there is any conflict at corners of reinforced concrete reinstatements then precedence for reinforcement positioning should be given in line with traffic flow.
Recoding the type of reinforcement within an excavation forms part of any quality assurance process. This can be done by taking photographs or by writing down the reinforcement position and measurements.
