About Us

SDL Utility Locating

A division of Smart Digging LLC

SDL Utility Locating is a trusted name in underground utility locating, serving the Greater Chicagoland Region with precision, reliability, and professionalism. We provide comprehensive private utility locating services for residential, commercial, industrial, municipal, and data center projects.

Our specialty lies in locating gas, electric, fiber optic, and communication lines – both private and public – as well as concrete and clay tile duct runs. These systems are often the most critical and difficult to identify, requiring the right combination of technology, training, and field expertise. By accurately locating these utilities before excavation begins, we help prevent service interruptions, costly repairs, and safety hazards.

With years of experience in the field, SDL Utility Locating has built a reputation for dependable results and client-focused service. Our team uses state-of-the-art electromagnetic and GPR technology, combined with a detail-oriented approach, to deliver accurate markings and thorough reporting for every project.

Whether you’re a homeowner installing a fence, a contractor managing large-scale construction, or a facility overseeing infrastructure upgrades, SDL Utility Locating delivers clarity where it matters most – underground.

At SDL Utility Locating, accuracy isn’t just our goal – it’s our commitment.

Our Services

Private Utility Locating

Locating and marking of privately owned underground utilities not covered by 811, including gas, electric, fiber optic, and communication lines, as well as duct runs.

Ground Penetrating Radar (GPR)

Non-invasive scanning to detect buried utilities, water and sewer lines, tanks, voids, conduits, and subsurface structures delivering accurate data for safe, informed excavation.

Cable Fault Detection

Detection and pinpointing of secondary and low-voltage electrical or communication cable faults for fast, efficient repairs and reduced downtime.

Beyond 811 Verification

After public utility companies complete their markings, we back-check 811 locators and utility company markings to verify accuracy and identify any unmarked utilities. We provide full verification services for residential, commercial, and industrial clients to ensure complete site safety before you dig.
