PRODUCTION TECHNOLOGY
Ballut Blocks precast floors are machine made voided units manufactured by the long line prestressed method, using vibro-compaction equipment.  Additives are included in the concrete mix to improve quality and curing.  Once they are cast, the precast units are sawn to lenght on their manufacturing bed.  In this way a clean surface finish on the sawn ends is obtained, ensuring minimum dimensional tolerances.
After the necessary curing of concrete has taken place the precast units are loaded and transported on trailers to the site.  Here the precast slabs are erected by Ballut Blocks personnel with mobile cranes.  The whole process, from the initial design of the slabs to manufacture, despatch and erection is backed by computer aided technical and administrative services.  Furthermore, concrete mix samples are regularly tested both
