Tying up those slabs
Another change since the Canterbury earthquakes is that all reinforcing in slabs on the ground must now be tied into the foundation wall reinforcing.

Another change since the Canterbury earthquakes is that all reinforcing in slabs on the ground must now be tied into the foundation wall reinforcing.
Lessons from the Canterbury earthquakes mean that all concrete floor slabs must now be reinforced with steel bars or welded mesh with a reasonable degree of ductility.
The BRANZ House insulation guide details the expected thermal performance for common construction options. It didn’t include the thermal performance of floor slab systems with polystyrene pods, but recent modelling means this data is now available.
All timber floors deflect to some degree under load, but a floor that deflects too much when walked on can be disconcerting. Floors rarely fail, but a bouncy floor often indicates a problem with the floor joists.
