- S7.6.1
- If the existing concrete is unreinforced and the trench is more than 1.5 times longer than it is wide, or where the reinstatement covers more than one slab, the reinstated concrete must be reinforced to mitigate early life non-structural cracking.
- S7.6.2
- In this case, the reinforcement must be placed in the upper part of the slab (with a minimum cover of 60 mm).
- S7.6.3
- In all other cases, when the existing concrete has no reinforcement, no reinforcement is needed.
