The sealcoating crew started by trimming the edges of the parking lot they were working on. Using a broom and squeegee, the crew sealed about a 3-ft. width from the edges of the lot. The main portion of the lots were sealed using two SealMaster SP 300 squeegee machines which Sonnenberg outfitted with custom-made 18- to 24-in. brooms on the back of the units. This allowed them to get a combination of squeegee and broom application across the whole project. The crew applied the first coat, let it dry, and then applied a second coat of sealer using the same application process.
Work started on lots for the university’s main campus. After completing about 75% of the lots on the main campus, Sonnenberg moved over to the other campuses (a dental school and a secondary school campus). The crew then went back to finish the main campus lots. “In all there was a total of 60 different areas we needed to sealcoat, including some roadways but mainly parking lots,” Mayberry says.
Sonnenberg subbed the striping work to B-Line Striping, East Alton, IL. Once sealcoating was complete on a lot the striping subcontractor came in to restripe. The finished lot could then be reopened even though the entire job had not been completed yet.
The crew worked between eight to nine hours a day and sometimes was able to complete work on smaller lots in one day’s time. Mayberry says the crew applied over 80,000 gallons of bulk sealer at the SIUE campuses.
Making the Deadline
In a job consisting of multiple lots in three different locations and a crew that had to work on other jobs during the same time period, it might seem that meeting a deadline is a major challenge. Sonnenberg had no problems sticking to the university’s deadline, though. In fact, the Sonnenberg crew completed the job in just 29 working days, well before the deadline.
