concrete over cables

[sarahproperty]

in my house there is no protective plastic sheathing or other conduits over or around the cables that have been installed in a recent re-wire. this includes around tv and phone cables.

in places, instead of bonding these areas, concrete has been applied to the walls to cover teh cables/keep them in place.

i have been told that such concrete can damage cables.
is this true?

concrete on walls? I think you mean plaster

And capping that should be put over cables is only really to protect the cables while the plasterer is skimming with his sharp float. AFAIK, plaster only has VERY long term effects on PVC. I'm sure someone else will clarify.

TV and phone cables are usually surface-clipped, unless they are being installed while a new house is being built, and before the walls are plastered.

they are most commonly stapled to skirting boards.

the cables are not being clipped to the skirting boards but are chased into the walls, before these are plastered. however, noone has covered the cables within the chasing before they bonded and, in some cases, concreted over these.

before i get the final plaster skim done i need to know whether this concrete/bonding/plaster will adversely affect the cables and affect quality

no one is contravening any regs by not using cable protection,so long as these cables are run correctly,safe zones etc. ,if the cables have been buried and bonded(plastered),then skim over and job done. I wouldnt think any one would concrete yr walls!..but then again a decent spark would use capping....and no,the plaster wont eat yr cable..in yr lifetime.

that's done when the walls are a bit naff. Rendering. Pretty sure it doesn't effect the cables. Is your property old? Have you had a damp course installed?

Sand and cemment render instead of bonding plaster is quite common I`m afraid then a final skim of finnishing plaster

Copper pipe does suffer from this and requires a protective sleeve. Plaster does effect it but I believe to a lesser extent.
