EnTech provides subsurface diagnostics that offer a dynamic view of underground infrastructure. Our stacking technologies create a comprehensive system that supplies our clients with timely and accurate information enabling them to make informed decisions.

Roadway & Bridge inspections begin with an Infrared Energy Pattern Analysis (IR-EPA) investigation. Our IR-EPA systems detect specific temperature pattern changes that assist us in locating and documenting voids, delaminations and cracks. It also determines locations and corroded reinforcing steel.

The IR-EPA investigation can be complimented with Light Detection and Ranging (LIDAR) for large aerial surveys. Sub-meter GPS accuracy ensures that field crews can easily locate roadway and bridge anomalies. This method enables EnTech to investigate the entire system without disrupting traffic and cut costs by allowing us to target areas requiring additional investigation.

Each investigation can be explored by further utilizing Second Generation Ground Penetrating Microwave Radar (GPR). GPR provides 3-D views of specific areas that require more detail than IR-EPA can provide. Information such as composition, depth, and size of underground anomalies can help our clients in their remediation of structural deficiencies.

THE PROJECT
EnTech received an emergency call from the Missouri Department of Transportation, requesting immediate investigation services on 2 interstate lanes after a partial collapse of a 10ft2 section of asphalt-covered concrete pavement which fell through the deck and onto the roadway beneath the overpass.

OUR TECHNOLOGY
EnTech started its pavement investigation later that evening and completed approximately 800 meters of roadway in about an hour. Traffic was kept moving by routing it around our moving data collection vehicle. Our patented, stacked technology, indicated in real time, that most of the pavement investigated contained areas where the cement binder had leached out of the deck, leaving only loose sand and aggregate trapped between thin layers of solid concrete on the top and bottom of the pavement.

THE PERSONALIZED SOLUTION
The lanes were immediately closed to traffic. The next day $2.5 million worth of steel plates were ordered to reinforce the lanes. *Three days later, while the lanes remained closed to traffic awaiting the steel plates, an area of approximately 150ft2 of pavement collapsed onto the roadway below the overhead lanes. This event and additional coring confirmed the results of the combined IR-EPA and GPR investigation.
