When spot repairs of old pipe lines, mainly sewers, are no longer viable, local authorities are faced with the problem of rehabilitating or replacing pipelines in the course of time. Replacement has the disadvantage of being very costly and disruptive to urban areas where the largest sewer networks are located.
The obvious answer is then rehabilitation, which can take the form of relining. DFHB Pipes are inserted in the existing pipeline with grout cementing them in place. In view of the savings municipal authorities are now allocating as much as 50% of budgets to rehabilitation. BFHB GRP Products are ideal for this application being lightweight, corrosion resistant, quality-assured, easily jointed and rigid to resist grouting forces.
