In balcony slab construction, GRC can provide a pre-finished moulded edge while simplifying construction. On ground floor concrete slabs, insulated GRC edge formwork can help in minimising heat loss from the building in cold climates. Similarly, in wall construction insulated GRC base course and sill units can be incorporated, which contribute to the overall wall insulation performance.
On the construction site, forms of glassfibre-modified concrete can be used in floor screeding, both in relatively thick concrete screeds and in thin self-levelling overlays.
