Contractor Chooses L&M Duragrout for Precasted Interlock Joints in New Dormitory

The new residence hall at Wayne State University (Detroit) is a 275,000 square feet, eleven-story precast concrete structure. There were hundreds of precast panels that had to lock together. All the interior channels had to be filled with fluid grout. This was no small project!

When grouting company, Ideal Contracting/ Barton-Malow of Detroit, was shown the blueprints and specs for the dormitory, they had to devise a way to make everything work together. Ideal/Barton-Malow's Project Manager Gus Cerku commented, "We had to rely on a consistent, fluid, non-shrink grout that would perform with the same specs with each and every bag. After each pre-cast concrete panel was lifted into place, we had to make sure each grout sleeve was completely full with no air pockets.

"We had to use concrete test cylinders as makeshift funnels for each sleeve and shore any gaps where the grout came into the joints to keep the grout from spilling down," Cerku continued. "There was no way to make a head box or to shore the job. A weather strip was used to minimize the grout leakage on the exterior faces. Luckily, L&M's grout could also be trimmed while still plastic and workable."

Cerku added, "L&M's Duragrout worked perfectly. This was one of the most challenging grout placements we've done, but where there's a will, there's a way."
