An old under-slab drain line was failing beneath a Groves home, so the repair went through a tunnel under the foundation instead of through the floors. Our crew ran new PVC drain lines through the tunnel, set them on all-thread hangers so the fall is correct, and the tunnel was backfilled. This was the second under-slab re-pipe of the day for us, and it was wrapped up by lunchtime. The homeowners kept their floors and their slab intact. If you are seeing slow drains, damp spots, or repeated backups in an older Groves home, a failing drain line under the slab is worth ruling out.
