Utility Locating Services

Precise utility locating services use ground penetrating radar and electromagnetic equipment to detect underground public and private utilities. These services help prevent damage, ensure safety, and keep projects on track.

Before any excavation or site work, it’s critical to know what’s underground. Public 811 services locate only utility-owned lines, not private systems such as water, gas, electric, or communication lines on commercial or residential property. C&M Subsurface provides private utility locating using GPR and EM technology to accurately identify and mark underground infrastructure, reducing risk and ensuring safe project planning.

Private Utility Locating

We locate and mark privately owned underground utilities to help clients understand what’s below before excavation or site work begins.

GPR Locating

We use ground-penetrating radar to identify and map buried utilities, structures, and other subsurface features with clear visual data.

C&M Subsurface

EM Wand Locating

We detect and trace metallic utilities and conductors using electromagnetic methods to confirm locations identified through GPR.

C&M Subsurface

Pipeline Locating

We locate and trace underground pipelines to verify their position and depth, ensuring safe and informed planning for future work.

C&M Subsurface

Void Detection

We use geophysical equipment to identify potential subsurface voids or anomalies that could impact ground stability or project planning.

GPR Locating

We use ground-penetrating radar (GPR) to identify and map subsurface features, including utilities, voids, and buried structures, without disturbing the ground.

C&M Subsurface

EM Locating

We use electromagnetic (EM) equipment to detect and trace metallic utilities and conductors, confirming their path, depth, and location.

Combined Methods for Greater Accuracy

No single locating method is 100% effective. By using both GPR and EM together, we cross-verify results and provide more complete, reliable subsurface data.

Frequently asked questions

How deep can you scan?

Depth depends on site conditions and soil type. Typically, GPR can detect utilities up to 8–10 feet deep, while EM locating is effective for metallic lines within similar ranges. Depth accuracy varies with material, soil moisture, and surface composition.

What are the turnaround times for reports?

Most reports are delivered within 2–3 business days after field work is completed. Larger or more complex sites may require additional time for data processing and map generation.

What are your rates?

Pricing depends on project size, location, and scope. We provide clear, upfront proposals based on your specific needs before any work begins—no hidden costs or surprises.

Are there situations where you cannot see a pipeline when there is one there?

Yes. Certain conditions, such as highly conductive soils, deep utilities, or non-metallic materials, can limit detection. We use both GPR and EM methods to cross-verify findings and reduce the chance of missed utilities.

What types of utilities can you locate?

We can detect a wide range of underground utilities, including electrical lines, gas, water, sewer, communications, and irrigation systems, depending on accessibility and material type.

What is included in the report?

Reports typically include field markings, utility locations, GPR images (if applicable), and mapped results. The level of detail is based on the client’s requested deliverables.

What areas do you service?

C&M Subsurface provides utility locating services across Texas, including Houston, Dallas, Fort Worth, Waco, College Station, Huntsville, Tyler, Abilene, and Beaumont. Click here to view our full service area.

What happens if you miss a line?

While no locating method is 100% effective, we take all reasonable steps to minimize the risk of error. If any concerns arise, we will revisit the site to review data and findings at no additional cost.

Can you provide a map?

Yes. Upon request, we can produce a digital map or drawing showing located utilities and marked features. The map format and level of detail depend on project requirements.
