Like I mentioned in the Underground section. We do all slab leak detections, and repairs.
Here is a quote " Have a underground repair needed at your home. Call us out. We can do Electronic Leak detection, and Excavation for you. Collier Plumbing will do the repair, and back fill with sand. Plus repour your concrete, and finish. Check out the photos in the underground Photos section of our Web Page."
