    Slab Leak: Direct Repair or Reroute

    A slab leak under your foundation can be fixed two ways — by opening the slab to repair the pipe in place, or by rerouting new piping around the failed section. Each has tradeoffs.

    Direct repair and rerouting both fix the leak, but they differ in access, disruption, and routing. The right choice depends on the leak's location and the piping's condition.

    Direct Repair

    A direct repair opens the slab at the leak location, fixes the failed section of pipe, and restores the concrete and flooring. It addresses the leak in place, which works when the leak is isolated and the surrounding piping is sound.

    The tradeoff is the slab work — breaking through concrete and restoring it afterward, including any flooring above.

    Rerouting

    A reroute bypasses the failed under-slab section by running new piping through the attic or walls instead. This avoids breaking through the slab, but it involves different access — wall or ceiling openings — and a new pipe route.

    Rerouting can make sense when the under-slab piping is failing in a way that makes repeated direct repairs likely.
