A growing problem in drain maintenance is decaying pitch fibre pipe. Widely used from the 1960s onwards, pitch fibre was developed as a cheap alternative to clay piping. Unfortunately the material has deficiencies which render it susceptible to deformation and blistering, as the layers separate and the pipe delaminates.

A new solution to the problem

Until recently, the solution has been to completely renew the drain in question. At KG Drain Services, we can now offer a more straightforward and simple answer. The pitch fibre pipework can be 're-rounded' using hydraulically inflated packers or metal pigs. A liner is then applied to provide internal structural support, restoring it to use. This process can be completed within a single working day - a financially attractive and hassle-free alternative to complete pipework renewal.
