“Trackline is a huge variable,” Schmitt said. “Once we get onto a hard grade where the trackline is good, our readings are virtually flat. Our four-track machine handles the variables in the trackline a lot better, too.”
All in all, the switch to stringless has proven to be a positive choice for CFI. “I guess if we had known it was this easy, we would have switched to stringless a couple of years ago,” Schmitt said. “I think at first everybody was a little apprehensive, but now they wouldn’t ever go back to stringline if they didn’t have to.”
Concrete Foundations Inc.'s parent company, Croell Redi-Mix, was created by Roger Croell in 1965 with one concrete plant in Lawler; it now has over 65 plants in six states. In 1999, it decided to enter into the concrete paving market by purchasing CFI. CFI started out hand forming sidewalks and driveways and grew into mainline paving. Today, the company specializes in concrete work, from driveways to interstate paving.
