In order to do everything quickly, you will need: metal detector, drill, concrete drill, pencil and sealant. First of all, it is worth marking a pencil in which you are going to make a hole. Before carrying out work, it is worthwhile to make sure that the metal detector is that there is no wiring or any other metal objects in the wall. Further, this place should be drilled using a drill, the diameter of which will be equal to the cross section of the cable.
