The Job Site: Plumbing Repairs

Foundation Repair and Plumbing Repairs are closely related. There are a variety of plumbing problems that a homeowner may encounter. Many plumbing problems are the result of significant soil movement. Other common problems are caused by tree root invasion and deterioration of the pipes due to age and material failure. If the home is over 40 years of age it probably has cast iron and/or concrete plumbing pipes and these pipes are at the end of their useful lives. Cast iron pipes and/or concrete pipes should be replaced with longer-lived PVC pipe. Regardless of the cause, the homeowner may need to repair or replace the under slab plumbing system after having the home’s foundation repaired.

After leveling a home foundation there can be unavoidable plumbing problems.  The repair of  plumbing problems should be done before filling voids under the foundation with mud pumping. Dawson Foundation Repair can provide you with expert under-slab excavation (trenching and tunneling) and ensure that these plumbing services are conveniently scheduled. The photos below illustrate a typical replacement of the drainage/sewer pipes underneath a home foundation.
