Now pouring our Firth TC3 re-levellable RibRaft® foundation designs.

This system consists of beams and ribs separated by a grid of 220mm deep polystyrene pods.

Firth’s TC3 system incorporates built in jack ducts (see the white pipes hidde…n in the mesh) which can be used to re-level the slab after future settlement, uses a strong fibre concrete mix and offers time savings on site, less excavation and cleaner construction whilst being seismically strong.

Davis Ogilvie is completing many specific structural engineering designs for this system each week as part of the on-going Canterbury rebuild. See More
