Sonar Drain Tracing
In order to locate the drain or specifically an actual defect that has been identified i.e. by the CCTV camera or jetting, we have the ability to pinpoint the location and the depth of the underground pipes.
This would be useful in the event of an excavation or to assess ownership and liability issues (limitations may apply).
This is accompanied by introducing a sonar emitting probe into the drain via the jetter, rods or camera.
This is then detected by drain locater on the surface. A digital signal is read showing the distance away from the probe or the depth, with the skill of the operative is accurate on the depth to within 10mm (conditions apply).
