Drain Sonar Tracing and Testing

Using sonar tracing, TBL are able to locate the line, depth and direction of drains, pipes, ducts and culverts. In conjunction with CCTV drain surveying equipment,TBL are also able to locate defective or collapsed drains or ducts to save time and cost of excavation. Drain tracing can be particularly useful and cost effective for construction companies wishing to develop sites making use of existing drainage rather than laying new pipe work. TBL offer sonar drain tracing using standard, specialist deep-sewer and even ‘floating sondes’ that are released on a lead or free-floating to trace longer runs.
