The Ballut Blocks beam and block flooring system has grown rapidly in popularity, especially in residential construction works.  Basically, this flooring system consists of a series of precast prestressed T-Beams with proprietary infill blocks between the beams.  A concrete topping is then applied over the beams and blocks completing the whole structure. The prestressing of the T-Beams depends on the span and loads required. 

Infill Blocks

The infill hollow concrete blocks are purposely designed by Ballut Blocks for this method of roof construction.  Different sizes of blocks are available according to roof specifications.  The lightness of the hollow blocks reduces dead load, allowing the beams to span further.
