When undertaking any drain CCTV inspection, our sophisticated and high-tech drain camera is inserted into the drain or pipe. It is then fed along the pipe and records direct to DVD all images.
Once the blockage has been identified using our drain CCTV technology, the technician then utilised a feature of the camera head to determine the ground depth of the blockage as well as it's precise location.
We are able to then mark the block/blockage area on the ground above. This specialised drain CCTV technology enables us to accurately locate the blockage to within 100mm.
