CCTV Surveys:

Domestic CCTV units, all with on-board jetting facilities, capable of surveying 100 – 225mm diameter drainage systems using a small flexible push rod system. Ideal for house and small industrial surveys.
Mini – Mainline CCTV units capable of surveying 100 – 600mm diameter drainage systems incorporating both push rod and mini tractor systems. Ideal for most industrial and commercial surveys.
Mainline CCTV units capable of surveying 100 – 1800mm diameter drainage systems including large tractor unit with “pan and tilt” facility. Length of survey from one access point can be up to 300 metres. Ideal for Water Authority, Municipal contracts and specialist “one-off” surveys.
All levels of survey are carried out by operators trained and qualified to the Water Industry International OS20X standard. On site input and validation of the survey results is carried out using the latest Wincan CCTV reporting software using on board industrial computers.
Sewer and Pipe Lining:

A four step process designed for the repair of cracked, fractured and broken pipes.

• Step 1
A pre survey is carried out by CCTV followed by pipe preparation by high pressure water jetting or specialist descaling.

• Step 2
The liner which is a polyurethane coated felt tube, impregnated with resin and catalyst system, is winched or pushed through the defective section of pipe.

• Step 3
Water or air is then induced into the liner expanding it to the contours of the host pipe and then is held under pressure where curing takes place usually in 1 – 2 hours. The lining at this stage has formed a hard, tough, structural pipe inside the old defective pipe.

• Step 4
Upon completion, the lined pipe is re surveyed by CCTV to check the installation and the results are recorded onto DVD.
