A guide to Beam and Block Flooring

Beam and Block Flooring has many advantages including the fact that it is easy to handle, quick to install and provides an immediate working platform for other tradespeople. It is also rot proof, draught proof and fire resistant is an all-weather form of construction and provides buildings with good thermal insulation.

Beams

Longley beams are made with C60 (60N/mm2 at 28 days) concrete. It is prestressed with 5mm indented steel wire. All of our beams are manufactured in an enclosed factory environment using fixed moulds. This means they have an enhanced finish as well as a superior dimensional tolerance.

Floor Blocks

All infill blocks should have 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. The exact compressive strength needed in floor blocks differs depending on their application. For example for garage floors, blocks with 7.0N/mm2 are required, whereas the compressive strength of blocks built into loadbearing walls should not less than that of the blocks used in the wall construction. If you are unsure about compressive strengths one of our expert engineers will be able to advise you on these to ensure the correct blocks are used.
