Constructing such a monumental building at the heart of one of the world’s busiest cities was a major feat of engineering, which presented numerous challenges.

The original specification was for a site-batched screed, which meant physically transporting plant and heavy materials in small quantities.

Despite the presence of the UK’s first purpose-built Jump Lift, the screed contractor, the Progressive Group, believed there must be a faster, more logistically friendly solution. And that’s where we came in.

Tarmac Building Products recommended the use of a bespoke blend of our unique self-levelling, synthetic, anhydrite screed that is 10-20 times faster to lay than conventional screed.

Normally flowing flooring screed is only pumped up to 10 storeys. However after extensive testing we were able to create a unique formulation capable of coping with up to 75 bar of pressure. This enabled the product to be pumped to the first 52 floors of the building, a first in the UK.

To ensure consistency the remaining floors were screeded with Truflow B a bagged version of the product.

Mixer vehicles were finely co-ordinated to ensure three were in attendance at all times. One supplying the pump, one ready to take its place and a third parked off site, waiting to replace the second vehicle.

If you’re looking to lift your business to new heights, talk to the experts. No one knows more about screeds than Pozament.

“ It is a pleasure to be working on the project with such an innovative and quality conscious contractor!”
