How It's Done

The Pipepoxy Process

A trenchless, 7-step repair that rebuilds the pipe from the inside. The deck, the tile and the landscaping above it never get touched.

  1. Locate and confirm the leak

    Perform a comprehensive leak detection and confirm the location with a pressure test on the pipe, hydrophones or a pipe camera. If a previous company located the leak, confirm their findings.

  2. Purge the pipe

    Using a blower/vacuum, blow the water out of the line. The pipe must be completely dry before you continue. Accumix will not adhere to a damp pipe.

  3. Sand the pipe

    The sanding process cleans and scratches the interior of the pipe, before and after the leak, to get it ready for the Accumix. If the disc comes out wet or dirty, keep drying before moving on.

  4. Blow out the debris

    Using a blower/vacuum, clean out the line one more time to remove any of the debris from the sanding process.

  5. Mixing and Pouring the Accumix

    Use the mixing chart to calculate how much Accumix the run needs, mix all three parts for at least 2 minutes, then pour it in to coat the interior of the pipe you are repairing.

  6. Coat the pipe and let dry

    Insert the proper size brush. Make at least 3 passes forward and back so the whole pipe is coated. This pushes the epoxy out of cracks, holes, or separations. FYI: The brush is capable of passing multiple 90s. Then hook up the dryer and allow it to operate for approximately 4 hours.

  7. Confirm the repair

    Check that the Accumix test sample has fully hardened, then pressure test the line with air only. If the gauge is holding and not losing pressure, Pipepoxy has done its job and the leak has been repaired.
