Sonar Drain Location / Drain Mapping
Sonar drain location can be simply used to pinpoint a defect within a drainage system or indeed the mapping of an entire drainage system, providing a plan of the drainage system on completion. Sonar location can also be used to verify the depth of a drain. This is especially useful in helping to provide an accurate quote, therefore ensuring there are no nasty surprises after work has been started. N.B. Sometimes carried out in conjunction with a CCTV survey.
