Advanced Technology

Our fleet of CCTV Rigs and High Pressure Jet-vacs, based at our depots throughout the UK can respond quickly and effectively to an array of client requirements. A complete range of high-tech solutions utilising the very latest technology in hardware and software is on offer. Our sophisticated equipment allows surveys to be carried out up to 500m from a single entry point and explosion proof equipment for use in hazardous locations is available if required.

Highly Trained Operatives

Our personnel are highly experienced and specially trained to enable working in confined spaces, some with additional sewer traverse certification. Additionally all Rig Managers are qualified to a minimum of OS19X and OS20X standard with a number also qualified in OS21X Brick Sewer Defect Classification. Each crew has a qualified first aider and a team member trained in Road and Street Works Act (RASWA) signing, lighting and guarding.

High Quality Reporting

Alongside our sophisticated CCTV equipment, we provide all our clients with comprehensive reports using the very latest software, high resolution photography, 2D / 3D drawings and a survey report on AIMS™ detailing structural faults, debris and intrusions in accordance with all current industry specifications. All surveys are fully quality checked by our data processing department, however in emergency situations uncontrolled data can be provided directly from the rig at the time of survey.
Our CCTV Survey vans have predominantly been used in tandem with our jetting crews on schemes for various water authorities. The team produce a final Wincan report from site, which is supported by HQ survey footage. Both the report and CCTV footage are uploaded into Sewer Viewer (see Sewer Viewer). All major defects are reported directly to the client (from site) to ensure quick resolution.
