I've got an SWA cable being put down under my patio, which happens to be quite low and needs to be built up on a bed of concrete, with a sand/cement mix going on top.
I've already found a previous post that mentioned concrete has corrosive type effects on SWA cable, so I'm just wondering how to do this? If it's not okay to lay SWA in a concrete mix, is it okay to lay SWA within a sand/cement mix instead?
The picture shows the SWA coming out in a mix of stones. This is where the concrete bed was going to be poured over.
Thanks,
Simon.
