Allied has been serving customers trenchless sewer replacement/repair requirements for years, so we know this end of the business pretty well. There are occasions when a trench has to be dug. Sometimes we use a combination of digging and the steel bursting head technology to correct the pipe slope if the grade is wrong. That being said, we always endeavor to leave your property in the best shape we can. Most of the time you’d never know we had been in your yard at all. Call Allied Trenchless at 509-371-8706 to talk to one of our people about fixing your sewer lines.
