Underground Utility Survey

TerraVisio Geosolutions (UK) Limited offers underground utility surveying and mapping services, to accurately locate the routing and depth of all buried services.

Using the latest Ground Penetrating Radar (GPR) and Electromagnetic Locators (EML) technology, we can identify cables (electricity, telecom and fibre optic), metallic pipes, gas and water pipes, voids, tunnels and drainage routes. 

By using the state-of-the-art technologies, we help our clients effectively manage their risks by identifying and avoiding buried services and hazards or hidden obstacles to development.


All of our surveys are carried out in accordance with “PAS 128:2014 Specification for underground utility detection, verification and location”.


Our team of surveyors provide complete surveying solution from on-site utility detection to provision of site-specific utility service plans.

We can also undertake a full topographic survey of the site, producing a highly accurate survey plan or above-ground features.


There are four survey types, namely;

TYPE D - Desktop Utility Record Search (DURS).

TYPE C - Site Reconnaissance.

TYPE B - Detection.

TYPE A - Verification.


With our experienced personnel, TerraVisio Geosolutions specialises in delivering all survey types and in particular the Type B.
