CCTV Drainage Surveys
From pipe cleaning and clearing, CCTV drainage surveys and diagnostics to drainage repair using traditional and no-dig techniques, Survey Central offers total drainage solutions and accurate investigation of blocked drains, pipelines and sewers without the need for digging and excavation work. We use remotely-controlled, specialist camera systems and software to carry out a CCTV drains survey. The specialist software used enables you to see the results for yourself on DVD, all supported by a full technical report.
Specialist services include:
- Confined Space Work – Survey Central have the experience, certification, skills and knowledge to undertake drainage based projects ranging from tanks, enclosed drains and sewer systems to manhole chambers. Confined space entry needs to be undertaken by trained engineers using certified/tested safety equipment including harnesses, safety tripod and winch, gas detectors and escape equipment.
- Sonar Tracing – Once a drainage problem has been located on a CCTV drainage survey, the exact location of the defective or collapsed drain can be identified using special sonar tracing equipment and will locate the line, depth and direction of the drain. The use of sonar tracing essentially eliminates the possible guesswork as the results will identify the depth of the drainage problem, exactly where the pipe work is and in which direction it is flowing. The results will then help in deciding on the most suitable method of repairing the fault and if needs be the accurate location to carry out a repair.
- Water Jetting – The most efficient drain/sewer cleaning technique is high pressure water jetting. Central Alliance has a range of water jetting equipment that can be used in a variety of applications that are capable of undertaking work on all types of systems.
