A reinforced concrete topping should always be applied to an insulated floor. Please refer to the specific BBA/Kiwa certificate for the reinforcement specification.

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

As respected beam and block floor suppliers, we know that this really depends on the scale and nature of the project, but as an example, we would expect our installation teams to install approximately 200m² per day.
