Marking / Identification & Protection of Cables Shallow Buried in Slab

[JezNZ]

Hi,

As is typical, civil contractors have screwed up requirements for conduits penetrating a concrete slab, for equipotential bonding cables. This is a wastewater treatment plant on an Industrial site.

I have proposed to allow the contractors to chase into the concrete slab and the cable will be direct buried into the slab with 30mm grout cover (this is all that is available above the rebar).

My question is, in my local regulations while there are many requirements for buried cables, there no stipulated requirements for embedded cables in concrete slabs. I'm concerned about the possibility of future equipment being mounted/moved on the slab and the cable could be hit by mounting bolts etc, so what methodologies are employed to identify a cable direct buried in slab?

At the very least, I expect to detail covering the cable on 3 sides with polymeric cable protection covers.

Thanks
