The MAXRaft Concrete Slab Floor System (MaxSlab) can be used to construct steel reinforced, concrete slab-on-ground floors subject to specific engineering design for buildings within the following scope:

• Ground floor slabs for timber-framed buildings, within the scope of NZS 3604, or other similar lightweight constructions where they are subject to specific engineering design; and
• Built on 'good ground' as defined by Acceptable Solutions and Verification Methods for NZBC Clause B1 Structure; or,
• Built on 'TC2' type ground within the 'Canterbury earthquake region' or moderately to highly expansive soils, subject to verification and assessment by a Chartered Professional Engineer

See BRANZ Appraisal 1054 for full information.
