WHAT WE LOCATE

PENHALL PICKS UP WHERE 811 LEFT OFF

Penhall Technologies stands out as a private utility locating company, offering comprehensive services to locate utility lines beyond the scope of what 811 free services cover. While 811 focuses on public utilities up to the meter, Penhall Technologies goes the extra mile by locating private underground utilities on private property.

Our Experts Locate:

  • Gas Lines
  • Power Lines
  • Communication Lines
  • Sewer Lines
  • Cable Lines
  • Underground Storage Tanks
  • Underground Pipes

Identifying private utility lines, such as water lines, natural gas, or septic systems, can prevent leaks and costly delays. Penhall Technologies' experts ensure every hazard is accurately located.

DETECT HAZARDS

COMPREHENSIVE UTILITY LOCATING SERVICES FOR SAFE AND EFFICIENT PROJECTS

Our utility location experts can detect and mark subsurface hazards that would otherwise endanger your project and personnel. Penhall Technologies, a leader among utility locator companies, provides comprehensive private utility locating services for construction and demolition projects of all scales, including residential properties, nationwide. Using advanced ground-penetrating radar (GPR) imaging technology, our experienced team offers precise utility detection services, identifying and labeling underground utility lines, tanks, and pipes.

Safety is paramount when it comes to any construction or excavation project. Striking a subsurface hazard can lead to severe injuries, costly repairs, and significant project delays. By utilizing our utility locating services, you ensure the safety of your team and the integrity of your project. Our cutting edge technology allows us to detect and map utilities with high accuracy, helping you avoid potential dangers and maintain a safe work environment.

Penhall Technologies prides itself on using the latest technology in utility locating. Our advanced GPR Scanning imaging equipment provides real-time data, enabling our analysts to make accurate assessments quickly. Whether you are dealing with complex urban environments or straightforward residential properties, our technology ensures that no subsurface hazard goes undetected. Trust Penhall Technologies to deliver the highest standard of utility mapping and detection services, ensuring your project stays on track and your team remains safe.

GENERATE A DETAILED MAP OF YOUR SITE’S UTILITIES FOR FUTURE REFERENCE

Traditional utility locating is ideal for undisturbed sites, but GPS utility mapping provides a permanent reference, eliminating the need for repeated locating. Our underground utility mapping service uses location data from our utility locating process to create detailed maps of underground utilities. These maps, exportable as KMZ, KML, or SHP files, are color-coded and tagged with essential metadata.

Accurate, Detailed Mapping GPS utility mapping removes the need for frequent GPR utility detection services, allowing you to dig with confidence using a GPS unit. Accurate to within 6 inches, our mapping is more precise than most underground work requires.

WHAT IS UTILITY MAPPING?

A utility map shows the location and identification of buried pipes, lines, and cables. This process involves locating all site utilities, including sewer, gas, water, and communication lines, providing a comprehensive utility map directly related to above-ground structures.

Penhall Technologies provides digital and PDF utility maps of all site utilities, public or private, including depths. Our maps support seamless project collaboration and communication. This  helps save money by providing accurate, up-to-date information, avoiding costly mistakes, and locating hidden utilities.

BENEFITS

PENHALL’S PRIVATE UTILITY LOCATING SERVICES KEEP YOUR PROJECTS SAFE, ON SCHEDULE AND ON BUDGET

Our utility mapping service provides a permanent record, eliminating the need for repeated locating and enhancing project confidence.

Penhall Technologies excels by offering detailed digital and PDF maps of all site utilities, both public and private. These maps are color-coded, tagged with essential metadata, and exportable in various formats for seamless collaboration.
