Accurately Identify Utility Connections Without the Need to Excavate

When it comes to understanding what lies under the ground beneath our feet, it's not always necessary or practical to begin with excavation. At T4 Intelligent Infrastructure, we provide non-destructive, accurate and speedy surveys, utilising the latest digital technology to achieve an accurate picture of the area.

Using our arsenal of 21st century solutions, we can detect hidden power cables, underground water systems, data networking cables, gas and water connections and more besides, allowing you to accurately route and plan your works, without the risk of damage to existing utilities.

We carry out work across the area, including in Suffolk, Essex, Norfolk, Kent, Cambridgeshire, East Anglia, Hertfordshire, Lincolnshire, London and Surrey.

Our Main Ways of Mapping Underground Networks

Ground Penetrating Radar
Ground Penetrating Radar

This technique uses radar pulses to ‘see’ into the ground. The signals bounce off pipes, cables etc and helps create an image of what lies beneath


Electromagnetic Detection

Here we use electromagnetic waves to pick up signals from power cables and communication equipment.


GPS Survey
GPS Surveys

GPS surveys allow us to accurately survey a large area at minimal cost. Using satellite positioning, we can collect pinpoint geographical data to help us measure plot size, terrain and flood risk.

Digital Trial Excavation
Digital Trial Excavation

Through the excavation of a small ground sample, we can gather data on soil quality and composition. This means we have an overview of the land’s geological condition and any risks that stem from it without any large-scale excavation work.
