Quake-stricken Christchurch was the ideal location for the 1st of the new Allied READY Super Slab using QPOD™ as a sustainable alternative to traditional polystyrene pod void formers within the flooring system. Polystyrene pods can be directly substituted for QPOD™, with four pods replicating the standard 1100mm x 1100mm square and 220mm deep polystyrene pods.
This was the first of many to come following Allied Concrete’s alignment with QPOD™ Flooring System jointly bringing to the market the first CodeMark Certified plastic pod raft flooring system in New Zealand.
READY Super Slab has a BRANZ apprasial and is CodeMark Certified. Having a CodeMark Certification means building consent authorities will accept READY Super Slab as complying with the New Zealand Building Code (when used as specified in the CodeMark certificate). You will still need to apply for building consent, however the CodeMark means no delays at council.
Southern Foundations SFL laid the foundation system challenging all aspects of the product, this was the first time they had used the product and were looking forward to be involved in the roll-out in the southern & Otago regions.
The day following the lay of pods saw a fierce Southerly blow up over Christchurch, the layer’s first reactions were “what is happening to those pods!” as the case was many local build sites using polystyrene pods spent the next day collecting broken pods from about the neighborhood while the QPOD’s were sitting tight un-moved. Even without mesh or D12 bar holding the QPOD’s down they will sit tight in high wind conditions.
Based on the ‘Raft Floor’ or ‘Waffle Pod’ floor concept QPOD™ simply swaps out traditional 1.1m x 1.1m polystyrene (EPS) pods at 1200mm centres with a 100% recycled plastic pod. 4x QPOD’s join together to form the full 1.1m pod.
Standing at 220mm tall QPOD features an additional built in 40mm upstand to hold your mesh at the correct cover, no bar chairs required and ensure your steel is sitting in the middle of your slab not down on the plastic pod. This foundation in Christchurch was laid on TC1 Good ground and was built to the spec of Allied READY Superslab foundation system, because of the narrow join in the middle of the plan this meant engineers input needed to be made outside of the CodeMark cover, SED (Specific Engineering design).
Within the CodeMark Parameters projections are permitted in the plan design providing they are regular and a minimum area to perimeter ratio of 1 is maintained for the foundation has a whole. Detailing of control joints (saw cuts) and re-entrant corners is important to minimize the risk of shrinkage cracking for buildings with projections.
