When a water leak or plumbing issue is found in pipes that are buried under ground or a concrete slab, excavation or tunneling is required. Excavation means digging a trench with a backhoe or breaking a hole in the slab with a jackhammer. Tunneling is another option that allows us to fix plumbing issues with underground pipes. Our services include hand digging tunnels and access holes, trenches and excavation for plumbing repairs.
