Bridge Deck Survey in Cleveland, Ohio
Infrasense was in Cleveland, Ohio last week to perform a ground penetrating radar (GPR) survey of a relatively new bridge deck in order to map the concrete cover.
Bridge Deck Testing in North Brookfield, Massachusetts
Our team recently completed testing on a bridge in North Brookfield, MA to provide as-built information including rebar spacing, rebar diameter, and concrete compressive strength in support of a load rating. In order to collect data on the culvert underside, Infrasense engineers used wetsuits and a small raft to keep themselves and the testing equipment dry…

Infrasense Carries Out Nondestructive Infrared Evaluation of Bridge Deck in Wisconsin
This past summer, Infrasense surveyed a bridge deck in La Crosse, Wisconsin using infrared for deck delamination detection according to ASTM D 4788 – 03. The equipment setup involved a dedicated vehicle mounted with a high resolution, distance triggered FLIR infrared camera synced up with a high-resolution visual spectrum camera. Both devices capture a whole…
