A drain which requires lining may have one or more lateral connections, from other drains such as gullies or toilets. These would require lateral cutting after lining to re-open any such inlets. Before installing a liner, lateral connection points are identified and measured. Once the liner has cured, the cutter can be sent down the drain to the located connections. These connections are then reopened using a specially designed cutter unit, powered by compressed air from a large compressor, custom built within our vehicle. The cutter unit is controlled above ground by a trained engineer working in conjunction with a CCTV monitor unit, allowing full view and control of the cutting process from the camera mounted on the cutter unit, ensuring each inlet is opened and left flowing correctly.

- Fast return to fully functional drain.
- Lower cost than excavating.
- Low environmental impact.
- Insurance approved.
