CAT Scans, CCTV Surveys & Sonde Tracking
Advanced drainage diagnostics across Bristol & the South West — locate buried services, inspect pipe condition and map your drainage network with precision.
Precision Drainage Diagnostics
Before any groundworks or drainage repair begins, you need to know exactly what's underground. Our specialist survey team uses the latest CAT scanning, CCTV camera technology and Sonde tracking equipment to give you a complete picture of your drainage network — without a single unnecessary dig.
Whether you're a homeowner dealing with persistent blockages, a developer planning a new build, or a contractor needing utility clearance, our surveys provide the evidence you need to make informed decisions and avoid costly mistakes.
CAT Scanning
Cable Avoidance Tool (CAT) scanning locates buried utilities including gas, electric, water and telecoms before any excavation work begins. Essential for safe digging on any site.
CCTV Drain Surveys
High-definition CCTV cameras are passed through your drainage system to inspect pipe condition, identify blockages, root ingress, cracks, collapses and misaligned joints — all recorded to DVD or USB for your records.
Sonde Drainage Tracking & Mapping
A Sonde transmitter is inserted into the drain and tracked above ground to pinpoint the exact location and depth of pipes. Ideal for mapping unknown drainage runs and producing accurate drainage plans.
