HI

I am looking at doing a strip drain along the edge of a bondek suspended slab, which goes around the edge of the pool on 2 sides

Is this possible? Would it compromise the structural strength of the slab, and if it does is there anyway of strengthening the slab to allow the strip drain

Would appreciate a quick reply, as I have started the tiling on this slab and before i go any further i thought it would be a good idea to do a drain to stop the dirt and water flowing into the pool

the pic attached is on the short side of the pool (labelled 2) which is a blockfilled wall supporting that part of the slab

and bondek above

as well as the blockfilled wall (1) which I believe extends all along the long side of the pool supporting the slab

Maybe a structural engineer can do up a paid report if it is possible

Thanking all in advance

Hi david123n
I suggest you have the basement details reviewed and upgraded an issue will be corrosive salts/chlorine's and protective covering
also ask for an extended warranty... Ot, 6 years won't be enough
Cheers

hi Chris

can you explain a bit more what are the issues here and why?
sorry, a bit ignorant about all these

thanks

sorry, Ive just notice it's built
The concrete reinforcement is required to have sufficient cover to prevent it from corroding from the pool chlorine /salts adjacent your bondek reinforcement/permanent formwork has no such cover from beneath, you might want to check with lysaght engineers if they recommend it
You can xray the slab and locate the reinforcement depth within the concrete if you are unsure if it's not been built correctly before cutting and grinding the slab, also check the engineers notes that accompanied those details
cheers

Hi Chris

thanks

so if after an xray, and all seems good, then even though it is suspended, it is still possible to cut a strip drain?

would you need any extra re-inforcements at all?

thanks again

I suggest you contact the original design Engineer he would have inspected the works.
Generally when drainage channels are required Concrete edge thickening is placed
The reinforcement bars are bent to maintain the required cover
Cheers

Are you in Melbourne if yes contact burrat engineering he good at what he does he is a civil and structural engineer. Give him a ring , his name is Steve Buratt. Thats who we are using for our drainage system around our bouse. Good luck
