"I am the Manager of a municipal airport and we need to repack the expansion joints on our concrete ramp. We need 12,000 feet. This saves us an unbelievable amount of money. So much so it is feasible to do. The quote a contractor gave us was close to $40,000! Too much for us to spend on a job that really needs done. With your material we will be doing it ourselves. Bill S. Plymouth Municipal Airport, Plymouth, Indiana"
