GPR Inspection of CMU Wall
UCONN School of Law, Hartford, CT
.........................................................
Project Description
Whiting-Turner Construction Company hired IMTL, Inc. to inspect the concrete masonry unit (CMU) walls of an occupied building at UCONN School of Law, Hartford, Connecticut.
They began the inspection by drilling pilot holes into the blocks to visually inspect inside the wall. Visual inspection revealed that many blocks were not grouted properly and many of the grouted blocks did not contain rebar. Inspecting the entire wall with this method would have wasted too much time and caused too much damage. To avoid these problems, IMTL hired us to perform a non-invasive concrete imaging survey using ground penetrating radar technology. This enabled us to see inside each block and determine whether it was empty, grouted with no rebar or grouted with rebar. This information was then used by Whiting-Turner to pinpoint areas of the wall in need of repairs, thereby reducing the number of pilot holes that needed to be drilled.
