hstraf Posted January 23, 2014 Share Posted January 23, 2014 Hello,I need some help understanding what is the best way to run wires behind the wall. (I need to add two new electrical plugs.)The wall is built with plaque de plâtre (gyprock) that has a 10cm backing of rigid styrofoam (polystyrene), which is then glued to the cement blocks.I thought perhaps I could heat up a fishing weight and drop it down the back of the plaque de platre to melt the Styrofoam and create a tunnel... but in this situation I need to run the wires horizontally, not vertically.Any ideas how to do this? Thanks! Link to comment Share on other sites More sharing options...
