Polished slab for extension

[TARLOX]

Hey Tassie Kiwi

In my opinion, 2 layers of SL62 is not sufficent for a polished concrete floor slab. It should be more like 2 Layers of SL82 or 1 layer of SL81 for Polished concrete.

Depending on the span. I thought this was a suspended slab?

Yes and that is why shedhand will require a structural engineer to design the slab. My last comment was purely in relation to minimum reinforcement requirements for 'shrinkage control'. In my opinion 2 layers of SL62 is unlikely to be adequate.

It'll ben interesting to see what the Structural Engineer specifies.

Back again. The engineer specified SL81. Its all moot now anyway. The architect said the cost of the slab was 7K (36m2). My builder checked this figure with the guy who was going to do it and he said his quote was just for grinding and polishing. :eek:
Missus had a fit and decided 19mm Tas Oak T&G over structaflor sheet will do us.
We start next Wednesday (at last). I'm doing the Owner Builder thing and will be the labourer.
