    Considering the advantages and drawbacks of under slab tunneling versus traditional methods is crucial in choosing the most suitable foundation repair strategy for your home’s specific needs and condition [6].

The Plumbing Tunneling Process

To commence the foundation repair via plumbing tunneling, I first pinpoint the exact tunnel location of the plumbing failure using hydrostatic tests and elimination techniques. After isolating the leak, I chart the most direct and efficient tunnel path, generally the shortest and straightest line from the home’s perimeter to the site of repair.

The step-by-step breakdown of the tunneling process is as follows:

  1. Excavation:
    • For foundation repair, I excavate a vertical hole straight down from the exterior wall to position the tunnel beneath the home’s foundation, ensuring the width remains under 36 inches to reduce impact on the slab.
    • After reaching the support beam at the bottom of the exterior wall, the excavation continues vertically upward until it meets the underside of the concrete slab, a critical step in the foundation repair process.

    • The tunnel extends horizontally, adhering to a 3-foot by 3-foot size, and leads directly to the site of the plumbing breakdown, a scenario often encountered in foundation repair and under slab tunneling projects.
    • This technique permits a skilled foundation repair team or plumber specializing in under house plumbing to reach the compromised pipes without the need to disrupt the interior of the home.
  3. Repair and Testing:
    • The plumber executes the essential restorations to the plumbing lines and carries out pressure tests to confirm the resolution of all plumbing failures and to verify that no additional leaks persist.
  4. Backfilling and Mud-Pumping:
    • Post-repair, the tunnel is meticulously backfilled using the unearthed soil along with new dirt if necessary, a common practice in under slab plumbing and foundation repair.
    • Employing a precise method known as mud-pumping, a mixture of Portland Cement, sifted topsoil, and water is propelled at roughly 400 PSI to fill any cavities, thereby securing the foundation’s stability, a critical aspect of under-slab tunneling and foundation repair.

      Addressing safety concerns during the tunneling process is crucial, involving the evaluation of potential risks and the reduction of hazards such as soil displacement and environmental effects, all integral to foundation repair. The tunneling duration hinges on the required length, with crews typically advancing 6 to 8 feet daily. When it’s time for backfilling and mud-pumping, a member of the foundation repair team will require access to the home’s interior.

      By adhering to these procedures, I ensure the home’s structural integrity is preserved, offering a robust foundation repair solution to the current plumbing challenges.
