Llanedeyrn Progress Update

The steel frame went up at the Powerhouse Hub extension just before Christmas. Now the ground floor slab is being poured on a deep layer of thermal insulation and a Radon barrier. Further Radon protection measures involve the placement of a couple of sump boxes, connected to underground drainage pipes. If Radon is measured above a critical level at the completion of the project then an extract fan can be installed on the end of the pipework to draw out the gas from below the slab.
