Suspended block & beam floors are the most popular, simple and cost-effective form of ground floor construction in the UK. We offer a complete range of concrete blocks, bricks and slip blocks for use in suspended block & beam floors including Part E and Robust Standard Detail acoustic separating floors.
Block & Beam floors possess a number of distinct advantages over other forms of floor construction:
• Exactly the same blocks may be used for walls and floors therefore simplifying the build process.
• Long spans are readily achieved without intermediate support resulting in cost-savings and a quicker build.
• Requirements for thermal, acoustic and fire resistance are easily achieved.
• A proven and reliable construction technique which eliminates the effects of ground heave or shrinkage.
• A versatile method which may be used for ground floors and intermediate floors.
• A safe method; once installed, the floor may be used as a working platform.
• Flooring blocks are defined as NR (non-resisting) and perform no mechanical function to the overall structural strength of the floor. They simply provide a base fro the application of subsequent screed and insulation layers.
• For this reason, blocks must not be stood on or subjected to point-loading or impact in their laid-flat state.
• Walking boards must be used across beams to provide a safe working platform whilst working on the floor.
• The floor will only achieve full strength and integrity once the blocks are grouted into place and the subsequent layers applied.
Insulite and Dense concrete blocks suitable for use in floors:
Solid (Group 1) Insulite or Dense Concrete wall blocks of nominal dimensions 440mm x 100mm x 215mm with a compressive strength of 7.3 N/mm² or above.
Airtec Aerated Concrete Blocks suitable for use in floors:
The following block types are not suitable for use as Block & Beam Floor Infill:
