Catterick Concrete Plant and Pallett Hill Quarry

St Vincents Church in Sheffield was to be transformed into a new student accommodation complex. The renovation project required a mass filling of the existing basement with 20N/mm2 concrete. When contractor, Paul John construction approached CEMEX for a suitable voidfill solution, we proposed to use Porofoam, our low density foamed concrete. Using Porofoam enabled the pour to be completed in less than half the time than standard concrete. Due to it’s reduced plastic density Porofoam could be placed in much thicker layers reducing lateral pressures exerted on the 165 year old internal walls of the basement. Porofoam is also self-compacting and self-levelling, which made it much easier for the contractor to place in the network of basement chambers. Porofoam is available in a range of densities and strengths and is manufactured using our proprietary CEMEX admixtures. For this project CEMEX delivered around 60m3 of pre-mixed Porofoam over 2 days to fill the void which achieved the required 20N/mm2 concrete strength. Find out more about our foamed concrete.
