Infrasense engineers recently conducted a ground-penetrating radar (GPR) survey along a segment of road in northeastern Massachusetts in order to map bedrock topography. In this case, GPR proved to be an effective tool in mapping bedrock stratigraphy to approximately 25-feet maximum depth penetration. If you have an upcoming project where we can be of assistance,…
Infrasense recently completed a project where we used GPR to assess settlement issues along a roadway in eastern Georgia. The areas showing evidence of settlement were in the vicinity of an underlying culvert. The GPR survey resulted in maps of subsurface voids and areas with evidence of moisture ingress possibly contributing to the settlement issue.…
Infrasense has recently been awarded with a U.S. Department of Transportation SBIR Phase I project to develop a method for low-cost, rapid assessment of chloride content in concrete bridge decks. Assessment of chloride contamination is an integral component of bridge deck preservation; normally, it requires lane closures and drilled samples to assess only a few…
