Dawnus Civil Engineering were commissioned by Cardiff CC to construct a hydro electric power station at Radyr Weir. The £2.6m scheme comprised of damming the section of works from the River Taff and constructing the structure to house the Archimedes turbine screws. They required a concrete that could take the weight of the screws 3 days after pouring and asked for a 3 day strength of 50N.
Tarmac suggested TOPROC ED which is a high performance readymixed concrete suitable for use in industrial, commercial and infrastructure construction where high early strength is required.
