Prestressed Beams

Our beams are manufactured with C60 (60N/mm2 at 28 days) concrete, prestressed by means of 5mm indented steel wire. Longley beams are manufactured in fixed moulds within an enclosed factory environment, giving them a superior finish and dimensional tolerance.

Beam and Block Floor Blocks

Floor blocks

The infill blocks should be 100mm thick with a compressive strength of 3.5N/mm2 or 7.0N/mm2 and be able to support a minimum transverse load of 3.5kN on a 420mm span. Where blocks are built into loadbearing walls the compressive strength must not be less than that of the blocks used in the wall construction. For garage floor applications, blocks with 7.0N/mm2 compressive strength should be used.


The floor should be thoroughly ‘wetted’ and a 3:1 sharp sand/cement grout brushed into all joints.
