Houston Utility Locating & GPR Scanning

Private utility locating, ground penetrating radar, and concrete scanning for Houston contractors, engineers, and surveyors. We find buried and undocumented lines before excavation, directional boring, trenching, or coring begins across Harris County.

Why Houston Sites Are Different

A high water table, Gulf Coast clay, and no zoning underground

Houston's flat Gulf Coast geology means shallow groundwater, saturated Beaumont clay, and land subsidence, conditions that attenuate radar and complicate every dig. Layer in a no-zoning grid, the Ship Channel and petrochemical corridor, the Texas Medical Center, and I-45 and Grand Parkway work, and utility records rarely match what is actually underground.

  • Shallow water table and saturated clay that reduce standard GPR depth.
  • Dense petrochemical, Ship Channel, and industrial private utility networks.
  • No-zoning layering of lines from generations of Harris County construction.
  • Private lines beyond Texas 811 across commercial, medical, and civil sites.

GPR Scanning

Ground penetrating radar for utility conflicts, trench verification, voids, and non-metallic lines, with method and antenna chosen for Houston's saturated clay and high water table.

Houston Utility Locating FAQs

Common questions for Harris County projects

Does Texas 811 locate private utilities in Houston?
No. Texas 811 marks utilities owned by participating providers up to the meter or ownership point. Private lines on Houston commercial, industrial, and petrochemical property typically fall outside 811 and require private utility locating.
How does Houston's high water table and Gulf Coast clay affect GPR?
Shallow groundwater and saturated Beaumont clay attenuate radar and reduce GPR depth of penetration. We lead with electromagnetic locating, tune GPR to the site, and interpret results against Houston's Gulf Coast conditions before excavation.
Do you support petrochemical, Ship Channel, and industrial facility work?
Yes. Plants, terminals, and Ship Channel sites carry dense private utility networks. We locate electric, gas, process, and unknown lines before excavation, tie-ins, and boring across Houston's industrial corridor.
Do you support Texas Medical Center and institutional projects?
Yes. We support the Texas Medical Center, hospitals, campuses, and institutional facilities with private locating, GPR, and concrete scanning for expansion and renovation work.
Can you support flood-control, drainage, and detention projects?
Yes. We support Harris County drainage, detention, and channel work with crossing verification, directional boring investigations, and GPS/GIS documentation before excavation begins.
How quickly can you mobilize across Harris County?
Many Houston projects can be mobilized same day or next day depending on scope, access, and traffic control. Send the address and scope for a scheduling check.
Do you provide GPS or GIS utility mapping deliverables?
Yes. Projects can include GPS data collection, GIS-compatible files, KMZ exports, and PDF utility maps for design, records, and coordination.
