Repairing a busted cast-iron drain line beneath a concrete slab is one of the most challenging plumbing jobs a homeowner can face. Many older Louisiana homes were built with cast-iron drain systems that, after decades of use, can rust from the inside out, crack, or develop holes that allow water to escape beneath the foundation. Warning signs include slow drains, recurring sewer backups, foul odors, wet spots on the floor, or unexplained foundation movement.

The repair begins by locating the damaged section with a sewer camera and, when necessary, leak detection equipment. Once the problem is pinpointed, the concrete slab is carefully opened, the failed cast-iron pipe is removed, and new PVC piping is installed with the proper slope to restore reliable drainage. The line is then tested before the trench is backfilled and the concrete is replaced.

While it isn’t a small repair, fixing the problem correctly prevents continued water damage, protects your home’s foundation, and eliminates recurring sewer issues. Investing in a quality repair today can save thousands in future structural and plumbing repairs, giving homeowners peace of mind that their drainage system is built to last.
