  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • Underground Water Tanks: Understanding the installation process is the first step in safety inspections

    Underground storage tanks are increasingly becoming essential components of building projects, driven by rising interest in on-site rainwater and graywater collection and reuse. As a result, building officials may need to expand their expertise to include these products and their components. Some safety inspection work is obvious; for instance, checking that the installer or project owner ...

  • 5 Considerations for Choosing Pipe Bursting

    Homeowners who encounter sewer, drain, and water line problems often dread repairs not just because of the expense, but the major disruptions that they expect. Excavation, torn up lawns, and days of going without water are associated with traditional methods of repair. Fortunately, technology has made it possible to assess and fix pipes with minimal disruption by using a technique called pipe ...

  • Applications of Pipe Penetrating Radar for Advanced Pipe Condition Assessments: the Clark Regional Wastewater District (WA) Case Study

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids outside ...

  • An electromagnetic-based method for pinpointing leaks in buried pipes: a practical validation

    In this paper, a time domain reflectometry (TDR)-based solution for detecting water leaks in underground pipes is described and experimentally validated. The proposed method strongly reduces the inspection time that is typically required by traditional leak detection methods. In fact, it can successfully inspect pipes that are hundreds of meters long. In this work, two different configurations ...

  • Asset management and nondestructive evaluation of force mains in New York City

    Management of infrastructure assets has been gaining increased attention recently because of aging infrastructures. Wastewater infrastructures, such as sewers, force mains, etc., maintained by various municipalities across the nation are at increased risk of failure since they are buried underground and are usually scheduled for maintenance/repair only after a breakage. Force mains are a vital ...
