Ground Penetrating Radar for Accurate Utility Mapping

Utility mapping made accurate with RD LMX ground penetrating radar

Accurate utility mapping is essential for safe and successful construction projects. Hidden underground utilities can cause serious safety risks, project delays, and unexpected costs if they are not identified in advance. To avoid these issues, Sigma delivers reliable utility detection solutions using Ground Penetrating Radar (GPR).
The RD LMX GPR technology helps construction and infrastructure teams locate underground utilities clearly and accurately, without the need for excavation. This approach supports safer worksites, faster decision-making, and improved project planning.

Why accurate utility mapping matters

Before excavation begins, it is critical to understand what lies beneath the ground. Many project delays and accidents occur because underground utilities are unknown or incorrectly mapped. Traditional locating tools often struggle to detect non-metallic utilities or pipes with damaged tracer wires.
Ground Penetrating Radar (GPR) solves this challenge by detecting both metallic and non-metallic objects. It provides clear visibility of underground features, even when records are missing or outdated. This makes GPR a valuable tool for urban developments, infrastructure upgrades, and complex construction environments.

How ground penetrating radar works

Ground Penetrating Radar works by sending high-frequency radar signals into the ground. These signals reflect back when they encounter buried objects or changes in soil structure. The reflected signals are processed into visual images that show the location and depth of underground utilities.
GPR works well alongside electromagnetic cable and pipe locators. While electromagnetic tools locate conductive utilities, GPR adds another layer of confidence by identifying non-conductive pipes, ducts, and unknown structures.

RD LMX GPR systems for dependable results

Sigma is the only authorized distributor in the UAE for Radiodetection’s LMX100™ & LMX200™ solutions, purpose-built for accurate underground utility detection. These systems operate using ultra-wideband 250 MHz radar, selected to deliver clear and consistent subsurface images across a range of ground conditions.
Both systems feature high-visibility touch screens that make field operations easy and efficient. Built-in GPS helps capture accurate location data, while Wi-Fi and USB connectivity allow instant data sharing and reporting from site.

Key capabilities of RD LMX100™ GPR

The RD LMX100™ is a reliable solution for everyday utility detection tasks. It is effective in locating:

• Metallic and non-metallic utilities
• Utilities with broken or missing tracer wires
• Undocumented or unknown utility lines
• Trenches and disturbed soil linked to buried services
• Buried structures such as old foundations

Its lightweight design and simple interface allow operators to complete surveys quickly without compromising accuracy. This makes it suitable for routine construction and infrastructure projects.

Advanced detection with RD LMX200™ GPR

For projects that require deeper analysis and higher confidence, the RD LMX200™ offers enhanced features. It provides greater insight into subsurface conditions and allows operators to identify difficult-to-locate utilities such as:

• Non-metallic pipes including PVC and asbestos cement
• Underground electrical cables
• Concrete stormwater and sewer systems
• Utilities where tracer wiring has failed
• Underground storage tanks and drainage systems
• Septic components and non-utility structures

The LMX200™ allows users to create depth slices and review survey paths directly on the screen. This helps teams verify findings on-site and make informed decisions without delays.

Improving safety and reducing project risk

Using Ground Penetrating Radar (GPR) greatly reduces the risk of accidental utility strikes. These incidents can cause serious injuries, service disruptions, and costly repairs. With accurate subsurface data, project teams can plan excavation activities more safely and efficiently.Clear utility mapping also helps prevent rework and unnecessary downtime. This results in smoother workflows and better control over project schedules and budgets.
