Stainless steel reinforcing bar
Stainless steel reinforcing bar
(OP)
I'm looking at a swimming pool design in the UK and the architect wants the steps into the pool to be built into the concrete pool wall.
There is a requirement for a minimum cover to reinforcement in swimming pools to the British Design codes of 40mm but if we use stainless steel reinforcement in the step details can we reduce the requirement for cover? If so where is there guidance for this? I've had a really good look and I'm coming up short. If there is no specific guidance has anyone got any experience with stainless steel reinforcement in corrosive environments?
The architect wants to detail steps that are 60mm deep overall (they claim it is a detail that they have used , thus the maximum cover I could likely obtain is about 25mm, significantly less than the 40mm spec'd in BS8110.
Any comments would be graciously accepted.
Best regards,
Nick

I guess it depends on the step depth, width etc. but unless its something unusual you should be ok with normal rebar.

I don't know of any specific guidance for cover with stainless steel bars in pools (normally we work to BS8110 in mild steel) but I would imagine that stainless steel bars with 25mm cover would be fine (as stainless steel exposed directly to pool water is fine on its own).
I suppose tile and grout thinness has already been taken into account and you don't have to reduce the 60mm still further?

I found some guidance on the use of stainless steel rebar eventually but it doesn't provide any numerical answers. Just that 'you can probably reduce cover if the workmanship shouldn't be a problem' or words to that effect.

Even a man's foot 300 mm long would not be able to "insert his toe" 150 mm deep into a recess that small top to bottom, especially not while climbing. Why do they want that much depth in the recess?

Cheers for your views, chaps. Much appreciated.

Or shall I say oxidize??
