WWWHP (World Wide Warehouse Hai Phong) continued building the next phrase of their renting warehouse. The project is a suspended slab with 5400m2 floor area. The client wanted to have a flat floor according to Fm2 – TR34, the floor has been cast using a strip method, utilising a Dramix®  4D Combi slab solution enabling tight crack control and removing expansion joints.

The project was designed under ‘crack width’ consideration. With benefit of steel fibre, we could utilize the performance of steel fibre together with conventional reinforcement to act as moment resistance and crack control at the same time. The design provided a cost effective solution which met both ultimate and serviceability requirements.

High performance steel fibre Dramix®  4D plus mesh was used to carry 140kN post load. The Combi Slab solution makes it possible to design a monolithic slab, without joints, to meet tight rotation requirements from ASRS supplier. Providing an exceptional finished product.

Coca Cola Amatil new Distribution Facility in Queensland Australia, a 30,000m2 warehouse. This warehouse includes 9,000m2 of High-Bay Racking with an automated storage handling system. At 35 metres high, and with post loads of 27 Tonnes, the most suitable solution was a Seamless Combi Slab.   The remaining 21,000m2 uses our more typical Jointless slabs with Dramix 3D 65/60BG at 30kg/m3. With Dramix 4D initialised in the many foundations on the project as well.   McVeigh consulting engineers worked very closely with BOSFA and Bekaert® in determining the right solution for the Combi Slab to accommodate the different sorts of loading that will be applied to the slab. And they were able to utilise our Bekaert® Software to confirm the designs themselves for the fibre only slabs and the foundations.  A great example of everyone working together, with the tools available, to achieve the best possible solution in multiple applications on the one high profile project.

As any owner of a commercial facility knows the concrete slab is the life line of the operation, if it fails its very difficult to operate and keep up the demands of the day to day efficiencies required of any commercial operation. This is why the Dramix Combi Slab option offers such a perfect solution. With the removal of not only saw cuts but also dowelled joints, the risk of the slab not being operational from a damaged joint is completely eliminated.
With the removal of joints the overall slab can also be designed thinner and more robust and this is why container yards are now opting for this solution, the benefits far out way the risk of a failed slab.
Well done to Kerman’s, Perth Concrete Services and Holcim for an excellent job.
