ARD are specialists in pitch fibre re-rounding using the latest technology, we are able to carry out repairs to partially collapsed pitch fibre drains.Up to 60% deformity can be re-rounded using specialist machinery i.e hydraulic operated winches supported by an a frame directly over the inspection chamber. Pitch fibre drainage systems have been haunting the professional specifier and general public for many years. ARD locals re-rounded and structural lining technology know has a way of exercising the problem caused by pitch fibre drains.
Engineers preparing to shut off road adhering to health and safety
Engineer pulling through steel cable to prepare for hydraulic winch to be set up
Engineers have CCTV camera checked to make sure that steel cable is in the right position to allow engineers to connect onto the remote control winch
Engineer had difficulties due to a wooden support that has to be in the correct position in the drain to allow the cable to be pulled upright preventing any damage occurring to the existing manhole
Engineers using remote on the floor and also hand winching through the re-rounding tool (what we like to call in the trade, a metal bomb) which is pointed at both ends to allow to move slowly along through the crushed and deformed areas of the pitch fibre thus allowing it to pull back into shape
Engineers successfully winding up the last part of the re-rounding tool prior to a camera check and inserting a felt and resin liner to allow the broken drain to be fully repaired and guaranteed for 10 years
ARD were asked by a local building company to carry out some pitch fibre repairs to the main foul waste service of a brand new development approximately costing 2 million pounds.
After a CCTV survey prior to the work had been carried out by the builders it became apparent that the drain leading to the sewer was put in the late fifties after all the London bombings during the war. Pitch fibre back at this time appeared to be an easy and cost effective way of replacing drain systems. Below we have pictures of our engineers carrying out the setting up of machinery adhering to health and safety requirements.
