Underground Utility Survey / GPR Mapping

We offer accurate detection of underground utilities, including electricity cables, pipelines, and telecoms, using Ground Penetrating Radar (GPR) and cable detector for enhanced safety and project efficiency. Our GPR surveys ensure precise identification of underground infrastructure to support safe and efficient project execution.
Using the latest underground utility detection technologies, including Stream C, Radio Frequency Location (RFL), and Ground Penetrating Radar (GPR), we provide precise mapping and identification of all underground utilities. These include metallic pipes, plastic pipes, drainage systems, electric cables, communication lines. Our technology enables comprehensive tracing of nearly any underground utilities. In Saudi Arabia, our underground utility detection surveys adhere to international standards such as ASCE 38-02. Survey results are delivered in various formats to align with your project specifications, offering detailed and accurate utility mapping to support safe excavation and planning efforts. Other service levels and specifications can be provided upon request to suit specific demands.

Survey Level A - Verification

Utilities are surveyed using direct measurement techniques at locations where utilities are exposed, at inspection chambers or by exposing utilities using Man-Hole/Inspection chamber opening techniques.

Survey Level B – Detection (most popular)

This is the most commonly used PAS:128 category. Utilities are detected, traced and mapped using one or more geophysical techniques.

Survey Level C (reconnaissance)

Site reconnaissance survey to validate available utility records and to assess if there are any conflicts that need to be resolved.

Survey Level D (desktop utility records search)

Underground Utility records plotted to drawing utilising record data which is gathered from utility providers and owners.

Trail Pits

Trial pit excavation is a method used to gather subsurface information by manually excavating small pits or trenches. This process involves digging and removing soil layers to expose the underlying geological features, utilities, or structures. Typically shallow, trial pits provide a localized view of subsurface conditions.

This technique allows for visual inspection, sampling, and measurements to assess soil composition, groundwater levels, or the presence of buried infrastructure. Trial pit excavation is commonly used in geotechnical investigations, construction projects, and archaeological studies to gather essential data for design, planning, and assessment purposes.
