![]() This particularly applies to pallets of blocks and bricks. Whilst construction work continues care should be taken to avoid excessive loading beyond the intended design load of the floor. ![]() Where floating floor finishes are used a levelling screed is recommended. Normally dependant on the span, pre-stressed beams will have an upward camber. We do not recommend the drilling or shot firing of any fixings directly into our prestressed concrete floor beams. Similarly, T & G Chipboard laid over insulation with a vapour barrier between can be used. Where insulation is used a vapour barrier and minimum of 65mm screed is required. Sand cement screed may be directly bonded to the grouted floor. We produce, distribute, and sell cement, ready-mix concrete, aggregates, and related building materials. Fire ResistanceĪ half hour fire resistance is achieved in a floor using 150mm deep beam rising to one hour fire resistance when using a 225mm beam. CEMEX is a global building materials company that provides high quality products and reliable service to customers and communities throughout the Americas, Europe, Africa, the Middle East, and Asia. Gaps between multiple beams must be filled with C30 concrete using a 10mm aggregate. GroutingĪ sharp sand cement mix / slurry of 4 : 1 should be brushed into the pre-wetted and cleaned floor ensuring all joints are properly filled. Normally blocks will be 440 x 215 x 100mm, however the design software used to calculate loadings and produce beam layout drawings will accommodate all “floorblock” types. Blocks should have a minimum compressive strength of 7.0N/mm2 and transverse strength of 3.5N/mm2. Solid standard dense and lightweight blocks are used with varying densities depending on the thermal, sound or load bearing requirement for the floor (see Beamshield for an alternative thermal floor option).
