    Have drilled entry and exit holes through breeze block for av cables...only problem being they are uneven and jagged damaging said cables....can these holes be manipulated even and smoother using some sort of filler or foam filler?

    how big are the holes? One idea that springs into my mind would be to cut a PVC pipe with the right diameter so it'll fit in there nicely.

    You could wrap the wires in pipe insulation.

    Holes are roughly 15cm wide by 15cm depth, clean through supporting wall between living room and kitchen...original plan was to cut entry and exit sections in plasterboard but the gap between it and breeze block was too slim and cables could not be pushed through...it was too late for turning back so the breeze block went too...i now had an impromptu av cable cupboard behind the fridge for ultimate access.

    My only problem is that said holes are uneven and ragged and cable are showing wear and tear from moving equipment.

    My thinking now is to use some sort of concrete filler in holes to square off, then attatch pvc facing for shiny smoothness...have no experience with concrete though and i am unsure if this is possible or will i have to go with a foam filling to protect cables...

    hi!!
    how about removing the cables completely, then puting expanding foam in the hole when the foam has set then redrill the foam with a smaller diameter drill bit. just bare in mind i would use the foam sparingly and give it all of the instructed drying time.
    best regards
    nick.

    Cut a length of 4" waste pipe to suit, either bed in place with muck or exp foam and finnish off with a little bit of plaster.
