LKAB Minerals Gypsol takes low-carbon flooring to new heights
At the heart of Canary Wharf’s ambitious Wood Wharf development, LKAB Minerals’ Gypsol has helped deliver what is believed to be a record for the UK’s highest flowing screed pour. Reaching an impressive 177 metres above ground, the landmark 53-storey tower demonstrates how innovative, cement-free screed solutions can overcome complex high-rise challenges while supporting faster construction, reduced carbon impact and outstanding performance.
Innovation at 177 metres high
In the heart of Canary Wharf’s newest neighbourhood, Wood Wharf, a 53-storey tower has set a new benchmark for high-rise, low-carbon flooring solutions, with the help of LKAB Minerals’ Gypsol Binder. Delivered in partnership with Cemex and Loughton Contracts, this project showcases how cutting-edge screed technology can power faster, greener, and more efficient construction.
A thriving mixed-use development, Wood Wharf will provide 3,600 new homes, over 2 million sq ft of commercial and retail space, nine acres of public spaces, a GP surgery and a school – all designed to meet BREEAM Outstanding and WELL Platinum standards.
The challenge
Installing screed at a height of 177 metres within a 53-storey structure presented a unique set of engineering, logistical and performance challenges. High-rise construction places increased demands on materials, particularly when pumping screed over long vertical distances, where maintaining consistent flow and performance is critical, and Gypsol screeds fully meet these demands. Some screeds can struggle in these conditions, with increased risk of segregation and cracking, reduced workability and inconsistent final floor levels and finishes.
In addition to the technical demands, the project required a flooring solution that could support a fast-paced construction programme while aligning with the development’s ambitious sustainability goals. With BREEAM Outstanding and WELL Platinum targets in place, the project team needed to reduce embodied carbon while maintaining quality, tight tolerances and high levels of productivity. The solution needed to perform reliably at height and integrate seamlessly into a complex, high-profile build environment.
The solution: Gypsol TS-15
Gypsol TS-15 screed combines LKAB Gypsol binder, sand, and water. With a binder made from 98% by-product, TS-15 achieves an 88% reduction in carbon emissions versus alternative screeds, supporting the project’s pursuit of BREEAM credits.
The screed’s ability to be installed at depths as low as 15mm, alongside large seamless bays of up to 1,000m², improved efficiency and finish quality. High productivity rates of up to 2,000m² per day also delivered valuable programme and cost benefits to the fast-paced high-rise construction.
Collaboration in action
Early engagement and close collaboration were central to the project’s success. LKAB Minerals worked with architects, main contractor Canary Wharf, Cemex and Loughton Contracts from specification through to delivery. Bespoke mix designs were developed, logistics carefully coordinated, and ongoing technical support provided to ensure smooth installation.
Asa Nuttall, Divisional Director at Loughton Contracts, commented: “Pumping to these heights required the right screed and the right partners. Gypsol TS-15’s flowability allowed us to achieve SR1 tolerances – something traditional screeds could not guarantee.”
Results
The successful Gypsol screed installation at Wood Wharf is believed to set a UK record for the highest flowing screed pour. The project highlights how high-performance screed solutions can meet the demands of modern high-rise construction.
Through innovation, early collaboration and strong partnerships, LKAB Minerals continues to support more efficient, reliable and low-carbon building practices, even at new heights.
