  • some pics of us splitting big boulders over a sewer

    Here is a neat little job link where we had 2 granite boulders over a sewer line that was 9 feet deep and the rocks combined with the sprinkler system has sheared the sewer pipe at the foundation wall. With the 2 houses so close it was one of those jobs you had to have a plan to get done lol.

        Tool, What do you mean on the vote thing? I know for a short while we had post of the week but that has been gone for a long time...

        If there are areas you want improved please speak out instead of just saying we have issues. If we don't know about something we cant fix it.

        The expanding agent is called dexapan and is sold online, I have found it for sale locally as a generic no name product but did not try it because I needed to know it would actually work. The holes are 1.5" we tried 1.25 " before and it did not work so 1.5" is the deal. The tool to drill is air powered rock drills because they blow air down the center of the bits and it is always blowing the dust out so the bit does not seize in the hole, and it goes pretty dam fast compared to a roto hammer. We started doing this when we would find boulders in our path of a sewer burst, it's kind of a bummer to tell the people we are delayed 24 hours to continue but boulders are boulders lol.
