Sarnafil - Roofing - Concrete Decking

Guidance on some of the materials used to form roof decks can be found in Clause 6 of BS6229:1982.

Structural concrete decks can be classified as either reinforced (cast in situ), precast, pre-stressed or lightweight aerated.

Reinforced (cast in-situ)
Precast

Both reinforced and pre-cast concrete decks are likely to require screeding, to bring the surface to the required standard.

Concrete deck should be finished with a smooth, nib free float finish.
