Woolworths Distribution Centre, Heathwood, QLD
Bespoke Isedio ShieldJoint comes out top for performance, availability and value for money at Woolworth’s new, super-cool distribution centre.
The new 42,000m² temperature-controlled distribution centre for Australia’s biggest supermarket chain will provide fresher, faster, and more efficient deliveries of around 4000 frozen and chilled product lines to over 260 stores across Queensland and Northern New South Wales.
To optimise the performance of the highly insulated steel frame building, the concrete floor slab was made up of several layers, requiring the jointing solution to be installed on top of dual layered, low and high-density foam insulation. To accommodate the initial shrinkage, and further shrinkage from the temperature draw down, the original design drawings incorporated a plate armour joint which was no longer available.
To add to the challenge, head contractor, Vaughan Constructions, and concrete specialist, Kraftur, wished to minimise the number of joints and improve construction efficiency by increasing individual pour sizes, which would further increase the joint openings.
The contractors were therefore required to work with a joint opening of 35mm, which limited the number of options available.
Following a review of all available jointing products on the market capable of meeting the design requirements, Kraftur, in conjunction with floor consultants, FACE, settled on three final possibilities, including Isedio ShieldJoint, the innovative, leave-in-place, zero-impact, sealant-free joint system.
To ensure that the joints could be warranted as ‘fit for purpose’, in line with Kraftur’s contract conditions, the three options were then subjected to a detailed 12-point investigation, which included comparison of key criteria, such as ease of installation, sufficient anchoring, joint capacity, smooth joint transition and bending and shear capacity.
Whilst there were minor differences in performance, the decision was taken to go with Isedio ShieldJoint, which, being the only option actually made in Australia, carried a shorter lead time and lower risk of supply chain disruption.
Kraftur subsequently installed a total of 1170 linear metres of Isedio ShieldJoint to protect the joints in the freezer wearing slab layer.
Kraftur Project Manager, Murray Burgess, said
“We were really happy with the overall service provided by Leviat on the Woolworths Heathwood project. Leviat offer great products and after sales support. It was fantastic to have someone come to site and engage with our team while we were installing the joints. The Leviat representative took the time to offer solutions and listen to our ideas.”
GPT Industrial Development – Glendenning, NSW, Australia
Isedio ArmourJoint and Connolly Expansion Joint Solutions from Leviat, have been chosen to ensure high-performance internal and external floor surfaces for GPT’s latest warehouse development in Glendenning, NSW, Australia. The latest addition to GPT Group’s expanding logistics portfolio, the new warehouse at Glendenning is located close to the M7 Sydney orbital road for convenient access to the city’s arterial road network. The 16,000m² building will provide modern high bay storage facilities with a minimum 10.5m internal clearance, along with 7,000m² of external hardstanding.
The challenge for Costin Roe (Engineer), Face Consultants (Flooring Consultants), and Head Contractor, Prime Constructions, was to provide cost-effective slab edge protection that would allow for load to be transferred between the slab sections, as well as bespoke jointing solutions for the external hardstand areas.
Specialist concrete contractor, Conzpec, installed 1266 linear metres of Isedio ArmourJoint together with hybrid Connolly Construction Joint and Expansion Joint solutions, utilising the bespoke manufacturing abilities of the Isedio brand, together with Connolly Square Dowels and Sleeves, and rebate moulds to suit.
Prime preferred the solution offered by Leviat, as it included the popular Isedio ArmourJoint solution with adjustable divider plate which, due to its simple and effective design, made closing off the joint to the sub-base easy. Coupled with Leviat’s ability to combine the expertise of two well-known brands to provide a bespoke joint solution that was quick and easy to install, this made for a seamless supply solution for the head contractor.
