MAXRaft
Description

MAXRaft is the solution for an insulated slab being built on less stable ground, in particular the TC2 type ground encountered in Christchurch. MAXRaft is engineered to be seismically stronger in earthquake conditions compared to traditional concrete foundations. 

The perimeter footings and load bearing thickenings from the standard MAXRaft remain similar, ensuring that your perimeter and load bearing walls can be supported while maintaining the thermal envelope around the house.

With MAXRaft, the infill area of the slab is engineered to provide stiffened ribs throughout the floor with the additional advantage of maintaining a thermal break around the foundation rather than transferring heat directly to the ground between the ribs where it is lost, as is the case with traditional waffle floors.
