Is it possible to run sleeves (say steel pipe) through the commpacted fill for electrical wiring?
top Yep. Although we used PVC conduit. I have my environmental reservations about PVC, but it is the easiest, most flexible and reasonably priced method. You just position them as you go. We forgot about one and I cut a chase int he wall with the power saw using a masnary disk. I then used a bolster to chip it out, laid the conduit in place and bogged it up with wall material. Unless I pointed the spot out I doubt you would spot it.
