Established in 1964, Indiana University – Purdue University Fort Wayne (IPFW) is Indiana’s 5th largest college campus. In 2009, the campus’ ever-increasing student population grew nearly 11% over the previous year, setting a new enrollment record and creating demand for additional on-campus parking.

In early 2011, construction began on the school’s third parking garage. The garage, located on the north end of campus, would provide much-needed parking near the newly dedicated Medical Education Center. The project, on a tight construction schedule, was slated to be finished before student’s returned to the campus in the fall.

Coreslab Structures, the project’s contractor, had been working closely with Dayton Superior over the past year on the development of a new grout sleeve prototype. Dayton Superior presented the final product, the Sleeve-Lock grout sleeve, to Coreslab. Based on the product’s exceptional performance, Coreslab agreed to use it in the IPFW parking garage project.

Coreslab used Dayton Superior’s Sleeve-Lock grout sleeve in the precast panels that were stacked in the structure’s stairways. The design of the snug fit grout port tubes allowed for a quicker and more secure installation in production, eliminating the need for duct tape to hold the tubes in place. With other grout sleeve products, the center stops are often broken off requiring replacement of the grout sleeve. This was not an issue with Sleeve-Lock, due to the product’s solid design.
“Overall, the Dayton Superior Sleeve-Lock grout sleeve was of great quality and saved production time,” said Tim Meckes, Plant Manager with Coreslab Structures.
