Tank room

I`ve been asked to provide a tanking solution for a plant room, above a supermarket.
They always leak to varying degrees, so it needs to work, and not just be a superficial solution.
Its a powerfloat slab, with some nasty angles which might be tough to cove up vinyl. I would think I would need to box it out square with marine ply first if we were going down that route.
I was thinking 2x coats of epoxy dpm, but I would need to form some sort of cove round the perimeter first.
Anyone done that before ?

 

Is there something like fibreglass that you could mould round the edge of the floor and up the wall before you dpm it?

 

Could ask Sika or watco for a system? Or try a company called Triton. They do loads of dpm systems

 

Watco is the specified system. I suppose I could give them a call today and see what they say.
My thoughts were to dpm then sand blind the finish.

 

Don`t really know. I was thinking something like ardurapid. Let is semi go off, then use a cove tool.

 

I was thinking more like using it flush, just to waterproof the base of the wall, then just use pvc cove as normal

 

Just realised you weren't thinking of going over the top of it, so just ignore me lol.
I take it they are not overly concerned about looks

 

No, it just about the practicality of it. At some point it will leak, so needs to work.
