Christchurch's rocky foundations and cheap fixes

Christchurch has such crap house foundations, says Aucklander Bevan Craig of Underfoot Services. No, really.

It was using rubble concrete in its ring foundations until the 1960s when the practice ought to have been phased out in the 1920s. And right up to the earthquakes, new homes were being built without reinforcing mesh in their concrete pads because it saved a buck or two. That is the penny-pinching mentality you are up against.

You’ve got 65 per cent of the foundations not featuring in the guidelines at all. That means 65 per cent of the houses in Christchurch have been assessed wrongly. And if repaired, repaired wrongly too
