Specialist Utility & Subsurface Surveys | London & UK Wide

ACUO SI Ltd provides industry-leading subsurface mapping to help developers, engineers, and contractors mitigate risk before breaking ground. Our expert surveys identify and map buried services with precision, ensuring your excavation, piling, or demolition works proceed safely and without costly delays.

Our Utility Mapping Capabilities

Using advanced Ground Penetrating Radar (GPR) and electromagnetic induction, we detect and trace critical infrastructure, including:

  • Power & Telecoms: Electric cables, fibre optics, and telecoms ducts.

  • Liquid & Gas: High-pressure gas lines and water mains.

  • Drainage: Sewer runs, drainage networks, and concealed chambers.

  • Structural Anomalies: Buried obstructions and unknown subsurface features.

We provide surveys to PAS 128 standards, offering a structured, high-accuracy framework for underground utility detection that meets modern compliance requirements.
