Infrasense recently completed nondestructive testing of a concrete tunnel liner using various NDT methods. The objective of this testing was to assess the condition of the concrete and confirm the presence of grout behind the liner. If you have any upcoming projects where we might be able to help, we’d be happy to hear from…
Infrasense was recently in Connecticut completing nondestructive testing to map elements of an unknown bridge foundation, including the footing and underlying piles. If you have upcoming projects where having bridge as-built information would be useful, we would be happy to help!
Infrasense just completed data collection for a concrete structure evaluation project on a building in Revere, MA. Ground penetrating radar was used to scan over 50,000 sq. ft. of concrete slab, spanning several floors. Data collected will be used to identify the spacing and depth of reinforcing steel bars and identify other targets such as…
Infrasense has been busy the last couple of weeks completing non-destructive scanning of parking structures in MA and NJ. The results of these surveys include maps of concrete deterioration, rebar depth, and rebar spacing/layout. If you have an upcoming project where these capabilities would be of value, please email us at opps@infrasense.com
Infrasense has been busy with falling weight deflectometer (FWD) testing in MA, NH, and NJ over the past couple of months, completing testing along 15 state highway project sections. The FWD data is combined with ground penetrating radar (GPR) data and the resulting outputs include pavement layer moduli, pavement layer thicknesses, subgrade resilient modulus, effective…
Infrasense was in western Massachusetts this past week completing a suite of tests along the abutments of a bridge to quantify and map deterioration, as well as identify concrete compressive strength, rebar spacing, and rebar depth.
Infrasense completed a subsurface survey to map the location and position of an oil/water separator and drainage basin structure that had its access lids paved over during construction at the site. The rapid NDE survey consisted of using a portable, GPR Survey System manufactured by GSSI, Inc. to identify and map out the locations so…
#TBT In 1996, Infrasense worked with UMass Amherst testing railroad tracks to detect fouling in the ballast and deterioration in the wood ties using ground penetrating radar (GPR). Initial testing was done on a test track at the UMass Amherst lab and then equipment was mounted to a HiRail vehicle for field testing on a stretch…
Infrasense supported the research team at Northeastern University in developing a survey vehicle system to automatically detect and process surface and subsurface roadway defects. The project, entitled VOTERS (Versatile Onboard Traffic Embedded Roaming Sensors), is part of NIST’s Technology Innovation Program, and focuses on the subsurface sensing of pavements and bridge decks. Some of the…
Infrasense completed a subsurface pavement structure investigation of both directions of a 1-mile long viaduct on Interstate 93, just north of Boston. This viaduct, adjacent to the Leonard P. Zakim Bridge, leads directly into Boston, so minimal traffic disruption of this corridor is a priority. Infrasense used a high-speed ground penetrating radar (GPR) survey to detect…
