CUPOLEX® foundation slab System is, the most cost effective, advanced and sustainable solution for residential and commercial buildings. It is manufactured in New Zealand using 100% recycled non-toxic polypropylene.

Each dome easily inter-connects to create a self supporting permanent form-work structure that uses the age old principals of arches, domes and columns to give strength and transfer loads across the slab. That structural element eliminates the requirement for any internal reinforcing steel in non load bearing areas of the slab, (In typical soil conditions found in New Zealand) less concrete is required and the domes act as a chair meaning mesh sits directly on top of the Cupolex. All this means labour and materials are significantly reduced.

CUPOLEX® provides an air void under the foundation which lends itself perfectly for the venting of Volatile Organic Compounds (VOC's), Radon Gas and humidity or moisture to be passively vented away from the slab.

Developments built on former dump sites with high levels of methane or areas with high levels of thermal activity are particularly suited to the use of CUPOLEX®
