  • Pipe bursting prep setup.

    prepped for a pipe bursting job that required me to core drill a 7'' hole under the house to allow the bursting head to pass through the foundation. used my smaller coring setup as dragging my monster setup under the house was not going to be fun. all went well except when i hit a piece of rebar on the edge of the hole. so instead of cross cutting the 1/2'' bar top and bottom, i ended up having to rip the bar approx 3''. my smaller machine in low gear is rated for 6'' and i was pushing it at 7'' plus the rebar.

    today is the bursting job that consist of a 35' pull from under the house, through the wall, then under a tiled patio where it 45's and continues to the sidewalk at 45'' deep. ground is full of roots and hard rocky fill. pipe was all broken on the bottom and was only getting worse. i have maintained this line since 2004 once per year, but now it's history as it's beyond routine cleaning.

      I never got into coring, always bring in the pros, but I know several plumbing contractors that do their own. Have fun with the pull.

        pulling pit with square front wall. this is very critical to get the machine to stay put and not creep sideways. shoring is also important to keep from pulling into the dirt wall.

        a look into the pipe prior to the pull. this was the good stuff. under the patio was all broken up on the bottom.

          Did you camera the patio section after the pull? I ask because if there is no bottom in the pipe they will sometimes belly there because there is no resistance on the bottom then the pipe bumps up when it gets to good pipe.

            it looked fine as there was a 45 turn in the first 4' so the pipe took a new course with the new long sweep 45. amazing how it really shortened up the original camera distance with the new path.

              here is a sample i showed the homeowner when he got back home. it's a butt fused piece that is 3'' long that's been run over by a truck tire and flattened, then rerun to flatten it the other way, then flattened again. this shows the weld is not going to break.
