Wide Diameter Well Surveys


A specialist CCTV/Remote Operated Vehicle service

We offer a specialist wide diameter well and shaft CCTV survey service including the use of a Remote Operated Vehicle (ROV).

Our vast experience in this area has allowed us to carry out successful surveys in wells over 10m in diameter and over 300m deep. Both CCTV camera and ROV can provide orientation data on features and tunnel directions.

The ROV provides the facility for detailed surveys of the well or shaft walls with the ability to survey up to 450m along water filled adit systems and tunnels. This greatly reduces the health and safety implications of using specialist divers by allowing an initial survey of the hazards before divers enter the water or negating the need for diver entry at all.

The ROV can be used with a sonar attachment which provides measurements of well or shaft diameters and tunnel widths. (Tunnel heights are measured with the ROV depth readings.)
