CCTV - Tunnel - Shaft Surveys

Our Operatives are trained to City and Guilds standards in Medium and High risk Confined spaces.

We carry out the surveys by attempting to design the risk of entry, and in some circumstances we will carry out man entry procedures and walk the tunnels.

Our CCTV services include: Trunk Sewers, Local Sewer Networks, Tunnels, Shafts & Culverts.

Main line sewer Tunnel & Culvert surveys from 1200mm to 3000mm are surveyed using…

• Raft / Float survey systems with 1200m of fibre optic cable and can be live streamed upon request.
• 500m automatic cable drum with PTZ main line Crawler
• HDS Laser Scanning which can be mounted on various crawlers.
• “H” frame high-definition camera & lighting rig survey.
• Local Sewer Network from 150mm to 1200mm.
• 500m automatic cable drum with PTZ Medium Crawler
• 250m cable drum with PT Small Crawler
• Various pushrods.

Shafts are suveryed using:

• HDS Laser Scanning.
• Tripod, 4K pan tilt rotate camera with ethernet connection.
• “H” frame high-definition camera & lighting rig survey.
• Bespoke designs.

We also build trolleys and frames in house at our workshop.

We take safety into consideration first and will avoid any risks.

Then we build, test and deploy the trolley or frame to overcome difficult survey areas.
