Sewer rehabilitation

Trenchless methods are an economic solution for damage in old drainage system pipes.


Rehabilitation, not replacement

Trenchless rehabilitation is the solution of choice when there is no access to pipes on site or when the customer wants to save high costs and avoid problems resulting from masonry or excavation work. However, such repairs are often made more difficult due to changing pipe diameters and pipe bends. The right material choices mean that a solid, functional drainage system can be rapidly restored.
