Designed to resemble a billowing sail, one of the most fascinating and majestic structures in the world, the Burj Al Arab soars to a height of 321m, dominating the Dubai coastline. This all-suite hotel stands on an artificial island 280m (920 ft) out from Jumeirah beach and is connected to the mainland by a private curving bridge.
Fosroc was awarded the contract to provide a waterproofing solution that matched the unique construction challenges in this key project.
Working hand in hand with the project contractors and consultants, Fosroc identified the product combinations that would provide optimal performance in an environment that was man-made/artificial and surrounded by water.
Amongst a myriad of construction challenges, careful consideration needed to be given to the selection of concrete admixtures and products to provide comprehensive solutions in key areas such as waterproofing and pile heads.
More than 100,000 m3 of concrete was placed on the site via a vertical static line pump up to 220m high, with a further 30m line being used horizontally on each floor- only the final 2 metres of the 250 metres line being flexible. Thus reliability and accuracy were improved and wastage reduced.
Conplast SP 432MS and Conplast SP430 were the super plasticiser admixtures which met the specification for the concrete and eventually 300,000 litres of Conplast SP432MS and 100,000 litres of Conplast SP432 were utilised.
The waterproofing membrane system consisted of two layers of Proofex GPX, 1.6mm self adhesive membrane and Proofex Protection Board. The waterproofing was applied as a positive tanking on to the structural wall and below the concrete raft.
The Burj Al Arab is one of the most important landmarks in Dubai and in the UAE. Considering the harsh climate conditions and the standards set for achieving high quality concrete, the admixtures used not only met the customer’s expectations but exceeded them.
As well as meeting strength requirements they provided a total solution on permeability and water absorption requirements resulting in expanding life expectancy to the structure.
