Description

CUPOLEX® is a concrete floor system which includes plastic, dome-shaped concrete void formers to create concrete slab-on-ground floors. Concrete is placed over the modular pod void formers to create a waffle raft slab.

The system consists of CUPOLEX® Pods, Beton Stops, Flat Stops, Reinforcing Chairs and Load Spreaders which are all identified by the CUPOLEX® brand on the individual components.

The concrete used with the CUPOLEX® system is specified by the Reference Document or by the Chartered Professional Engineer.

CUPOLEX® is a concrete floor system intended for use within slab-on-ground floors on ground with design considerations of:

• on ‘good ground’ and ‘TC1’ type ground within the ‘Canterbury earthquake region’, as defined by the Acceptable Solutions and Verification Methods for NZBC Clause B1 Structure, using design details from the Reference Document; and,
  
• on ground with an ultimate bearing capacity of minimum 200 kPa pressure (as defined in the Reference Document) and with all other classification details of ‘good ground’ and ‘TC1’ type ground, using design details from the Reference Document; or,
  
• on ‘TC2’ type ground within the ‘Canterbury earthquake region’ or moderately to highly expansive soils, when subject to Specific Engineering Design by a Chartered Professional Engineer.

Scope

CUPOLEX® is a concrete floor system intended for use within slab-on-ground floors for either timber-framed buildings within the scope limitations of NZS 3604, or steelframed buildings within the scope of limitations of NASH Standard Part 2, or other similar light weight constructions where floor slabs are subject to Specific Engineering Design; and within the following conditions and limitations:

• Built on ground with an ultimate bearing capacity of minimum 200 kPa pressure (as defined in the Reference Document) and with all other classification details of ‘good ground’ or ‘TC1’ type ground within the ‘Canterbury earthquake region’; or,
• When built on ‘TC2’ type ground within the ‘Canterbury earthquake region’ or moderately to highly expansive soils, CUPOLEX® is subject to Specific Engineering Design as well as to verification and assessment by a Chartered Professional Engineer.
• Compliance with H1 Energy Efficiency is dependent on CUPOLEX® and project-specific details (including supplementary insulation where required) complying with:
  
  • a. NZBC Acceptable Solution H1/AS1 Fifth Edition and Verification Method H1/VM1 5th Edition for all housing, and buildings up to 300 m²; or,
  • b. NZBC Acceptable Solution H1/AS2, First Edition and H1/VM2, First Edition for buildings greater than 300 m²; or,
  • c. for building consent applications submitted before 3 November 2022, NZBC Acceptable Solution H1/AS1 Fourth Edition, Amendment 4 for all buildings within the scope of this certification.
