A broken pipe under the slab is one of the most stressful plumbing problems, because the traditional repair means breaking through the floor. Trenchless methods offer alternatives: lining to seal cracks, pipe bursting to replace pipe through existing openings, and limited-access tunneling in some cases. The right approach depends on where the pipe is broken and how, and we explain it clearly.
We camera and locate the pipe beneath the slab, identify the damage and decide on lining, bursting or limited access. Where the pipe is collapsed or badly offset under the house, we explain the options honestly, including when a small opening in the slab is the practical choice. We work to protect the floor and finishes.
