Pitch Fibre Re-Rounding

Pitch fibre pipes are made from layers of wood pulp and pitch pressed together with bitumen. This pipe is susceptible to deformation and blistering which is a major cause of household blockages.

We used a specialist re-rounding tool mechanically drawn through the pipe and once the pipe is round we then install a CIPP liner to prevent any further deformation, increase flow rate and supply structural strength.
