After many years of using drain locating equipment, we have finally found a system which offers tracing to a depth of 8 Metres, with an accuracy or 200mm
A small sond is sent through the drain to be traced, propelled by either High Pressure Water, or standard drain rods. Once the sond is within the vicinity of the section of pipe to be traced, the hand held locating device is passed over the ground showing a mapping system on the screen. The map guidance feature eventually plots the drain line ready for excavtion/repair.
We have recently completed two major excavtions based upon the guidance of this equipment, and in both cases the excavtions proved pin point accurate, thus minimising disruption and unnecessary excavation.
