Accurate, detailed and concise. These are all terms to describe CCTV drain surveys carried out by Drain Doctor.
CCTV drain surveys are a cost effective way of locating drain problems such as collapse, root ingress and damage caused by broken drains. Drain Doctor only use the latest technology, so imaging is pin sharp. We can also locate damage once identified using our sonar locators which are accurate to within a centimetre making repairs easier.
Drain Doctor’s trained operatives have a camera to cover all eventualities. For larger sewers and drains our crawler tractor systems can travel up to 250 metres from a single access manhole. Our small cameras are very flexible to negotiate bends and gully traps. We are also trained to industry coding standards and confined space training.
After years of working with both surveyors and consultants in all aspects of the industry, CCTV surveys can be carried out on foul water drains, storm and trade effluent streams. Culverts, shafts, tanks and manholes can be reported on accurately.
Our reporting systems can give very detailed structural condition reports. These use the best industry software and are available to customers on all formats including CD and DVD. Many drawings are configured digitally using mpeg, jpeg or pdf files.
