    Got a 4" sleeve I am trying to get to that goes under a 17' concrete driveway. The contractor decided to use a 4" drain line as the sleeve. He didn't cover either side, ran lighting wire through it and now I can't get through it because it is packed with rocks/road base.

    From one side I can go 7' before hitting it and can go ~9' from the other side before hitting it. I have tried a rock bar, long piece of re bar, and a pressure sprayer through a pipe. All to no avail. One of the big obstacles is that I can't get any of the rocks out if I am able to bust any part of the clog up.

    Any suggestions are welcome. Thanks

    Get a new sleeve installed, hopefully at someone else's expense.

    Or go around the house, and do without a driveway sleeve.

    put a HP nozzle on 1 end of a 3/4" galv. pipe and GH swivel on the other. quit jamming and packing the material, loosen and remove. it'll work, just be patient

    Do you think the pipe could be crushed? What about roto rooter? What about using boring unit?

    Disconnect the lighting wire and tape it to the pipe and pull it thru

    @WB- drive so going around wouldnt help. New sleeve may be an option if we can get someone else to pay like you mentioned.

    @jim- that is my first option tomorrow. Didnt have one with me and was 30 min back to pick it up.

    @MW- that is my ultimate fear. Didnt think about a roto rooter.

    @ DL- thanks.

    @ Al inc - i tried to just pull my wires back through and they would get caught. The lighting wire moves back and forth easily but taping anything with it causes it to get caught.

    Thanks guys. Keep any suggestions coming. I am off to get some m80s with long fuses in the mean time.

    The weep holes in field drain pipe aren't very big so no rock of any size could have gotten in if installed correctly IMHO.
    That said, i doubt the pipe would have rocks of any size in it, just 3/8 minus, dirt and fines.
    If the concrete truck was backed over an uncompacted trench it could have crushed (as mentioned before) the pipe but since you can reach 9ft and 7ft and the driveway is 17ft wide i would imagine that the pipe came apart during backfill.
    If that's the case you may be removing a lot of material.

    Might want to go rent a Sewer inspection camera also. Sunbelt I know has one available for rent. That way you know exactly what the blockage is.
