Trenchless sewer rehabilitation

Root damage, leaks, static failure: sewage pipe systems are increasingly outdated. However, the wider public remains unaware of the condition of underground networks. Each driver is a witness to the poor condition of crumbling roads, however faulty pipes and sewage remain unseen underground. Their critical condition only rarely becomes noticeable at ground level – namely when faulty piping causes flooding, undermining and collapsed surfaces after major downpours. In many German cities and councils those responsible are successfully dealing with the backlog of refurbishment projects. Clever keyhole technologies have been around for around half a century, capable of refurbishing pipes and sewage networks with almost no effect on the infrastructure at surface level.
