Beam & Block Floors
Installation
Longley's beam and block ground floors can be installed with the minimum of fuss and maximum effectiveness.
They are quick to install and provide an immediate, safe working platform that is rot proof and fire resistant. Beam and block ground floors eliminate problems associated with heave or shrinkage caused by ground movement and they are also squeak free. Services passing through the floor can easily be accommodated between the beams by removing blocks and making good after final positioning of the services.

Longley beams are available in two widths, both at 175mm deep. We can advise you which is more appropriate to your project.

Span Load Tables

Camber
The prestressed beams have inherent upward camber and due allowance should be made in the finishes to cater for this. Differential camber will occur where adjacent spans are of different lengths and where a change in direction of span occurs. The camber will generally comply with the recommendations of BS8110 and are predicted to be approximately 1/300th of the span.

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

Fire Resistence

The floor joists are non combustible; our Standard Beam has ½ hour fire resistance and our Wide Beam has 1 hour fire resistance.
