How do I break a concrete slab without damaging cabling running through it Leave a comment

I want to install fiber optic in my house. It shouldn’t be an issue except at some point my phone cable goes through a 5cm-thick concrete slab that was cast around it. This happens in a weird corner which makes using heavy machinery difficult. My plan right now is to break the slab around the cable with a hammer and a chisel.

Is there a big risk to damage the phone wire? Is there an other way to proceed you recommend?
