Outright Winner of the 2020 Concrete Society Awards

Concrete waterproofed with the Caltite admixture from Cementaid played a significant role in the construction of The Marshall Building which will form part of the world-famous London School of Economics. The use of the Caltite system resulted in simpler detailing, time-saving and general ease of construction for this project.
