Excavators gain built-in GPR scans

RodRadar has moved a tool that was once a pre-dig survey step onto the excavator itself. Its LDR Excavate product embeds ground-penetrating radar in the digging bucket, so the machine scans while it digs and sends live alerts to the operator in the cab. The company says the system is designed to detect buried gas, power, communications, water, sewer, oil and chemical lines in real time during excavation. The setup is already being marketed through equipment partners and has now been linked to an automatic stop system from Hexagon’s Xwatch unit. ### How is the radar actually built into the excavator? RodRadar says the radar is integrated directly into the excavator’s digging bucket rather than added as a separate cart or surface-scanning pass. The company describes LDR Excavate as a bucket unit with its proprietary sensing technology already embedded, with a display inside the cab that gives automated alerts during digging. The product page lists bucket options for machines from 1 metric ton to 40 metric tons. (rodradar.com) RodRadar says the attachment can be installed on new or existing excavators using standard interfaces, which is central to the pitch: contractors do not have to redesign the machine to add subsurface sensing. ### What changes when the scan happens during digging instead of before it? RodRadar says the main difference is timing. (rodradar.com) Traditional ground-penetrating radar is usually run from the surface before excavation begins, while the company’s system continues scanning as excavation progresses and the bucket gets closer to the buried asset. RodRadar says that allows the operator to receive alerts during the live earthworks workflow instead of relying only on earlier markings, records or potholing. Garney Construction described that shift in a June 2024 case study from a pilot at a naval base in Indian Head, Maryland. The contractor said a CAT 315 excavator fitted with a 24-inch LDR bucket alerted the operator to buried utilities, including position and depth, up to about 30 inches deep per pass. Garney said the six-week pilot identified at least eight buried utilities that 811 Miss Utility and private locating services had not found.

Xwatch and RodRadar said on February 23, 2026, that underground utility strikes remain a persistent safety and cost problem in construction. In announcing their integration, the companies cited U.S. figures of more than 400,000 incidents a year and roughly $30 billion in annual economic cost. Common Ground Alliance, which publishes the DIRT damage database, says its 2024 report is the industry’s main annual accounting of buried infrastructure damage, and its latest data showed 196,977 unique reported damages for 2024 in the submitted dataset. (rodradar.com) Garney said utility strikes cost the industry about $100 billion a year and reported 82 strikes of its own in 2023. In the company’s account of the pilot, the RodRadar bucket prevented an estimated $80,000 to $100,000 in direct and indirect damage during the six-week test. ### Does the system only warn the operator, or can it stop the machine? Xwatch Safety Solutions, part of Hexagon, said in February 2026 that it had integrated RodRadar’s detection system with safety-grade hydraulic controls. (xwatch.co.uk) The companies said the combined setup automatically halts the excavator bucket when subsurface utilities are detected during active excavation, while still allowing operator override. (rodradar.com) Equipment World reported on May 11 that the integrated “Stop Before Strike” system was shown at ConExpo 2026. The publication said Xwatch stops bucket movement when RodRadar detects utilities within about 6 inches of the bucket, and quoted RodRadar North America sales vice president David Hubbell saying contractors could rent the LDR system for $6,000 to $6,500 a month, versus about $16,000 a month for a vacuum excavation truck used for potholing. (xwatch.co.uk) ### What does this mean for who does utility detection work? RodRadar’s product material says the operator receives automated alerts in the cab without offsite expert analysis. That does not replace 811 notification or formal locating requirements, but it does move part of underground detection into the excavation pass itself, at the point where the bucket is about to make contact. The next public marker is commercial rollout of the integrated safety system shown at ConExpo-Con/Agg 2026 in Las Vegas.
