Why Utility Mapping & Verification Matters

Striking unknown or incorrectly marked underground utilities can stop projects, cause expensive repairs, and create serious safety hazards. SDL Utility Locating Utility Mapping & Verification service identifies private utilities that 811 does not cover, giving contractors, property managers, and excavation teams the accurate information they need to plan safely, protect assets, and keep projects on schedule.

Benefits of Utility Mapping & Verification:

• Minimize downtime and avoid unexpected delays
• Reduce repair costs and prevent expensive mistakes
• Protect personnel, property, and surrounding infrastructure
• Ensure compliance with excavation and safety regulations

How We Do It

Electromagnetic (EM) Locating

• Accurately detects metallic utilities such as power, communication, and service lines
• Provides precise path and depth information for safe excavation

Ground Penetrating Radar (GPR) Scanning

• Detects non-metallic or hard-to-find utilities, including plastic, PVC, or concrete-encased lines
• Complements EM locating for a complete view of what lies below the surface

By combining these technologies, SDL Utility Locating delivers a comprehensive, reliable map of all underground utilities on your property.

Documentation & Prints

After completing the locate, we provide a clear map or diagram of all marked utilities. This includes:

• Utility types and locations
• Approximate depths (if measured)
• Property reference points (buildings, fences, driveways)

This map ensures your team can reference the marked utilities during excavation, construction, or future projects, protecting your property and project schedule.

Compliance Notice

All customers must contact 811 before excavation, as required by Illinois law. SDL Utility Locating provides supplemental verification services only and does not replace 811.
