We want to thank you for the great job you did at Campus Baptist Church! You have even impressed some of our older men in the church. I especially appreciate the fact that you "sneaked" us into your schedule and got the job done before our special 75th Anniversary weekend. It was a huge success and we are grateful, Thank you again.

Jon and Ross, I want to thank you two and your crew for an excellent job at ISU this year, please thank Myles, he is always great to work with.


I know we are a challenging customer, we have a lot of events, issues, etc. that we need to try to satisfy and your crew is always willing to help in any way they can.


I visited with Mark Miller yesterday, he is very happy with the job this year! From my observation the coating is thicker and the coverage is much more uniform, thank you!

Communication with you all was very good. To echo Les' comments - a well planned and executed project with attention to quality details, while dodging rain drops Thank you.

We’re hoping to get at least 25 years out of this asphalt trail, which wouldn’t be possible if we hadn’t done any treatment on it.

Installed in 2012, we were starting to see a few cracks. I did some research, looking into Gee Asphalt. The GSB-88® asphalt preservation product looked like a really good option for us.

Franklin County Conservation takes care of 17 miles of bike trail and about 4 miles of asphalt trails. The rest is crushed lime. We are also responsible for over 22 parks totaling over 2000 acres, so we have a lot to manage with a limited budget. We try to make the most of every dollar we do have.


Most trail systems are grant-funded for the actual construction. Then, with the various grants, we have to sign a contract with a maintenance agreement. Some of them (grant-funded contracts) are 25 or 30 years.

With The Rolling Prairie Trail, we want to make sure to fulfill our end of that contract in maintaining this trail for at least 25 years. So, that’s another major reason that we decided to go ahead with the Gee Asphalt GSB-88® treatment—to save some money in the long run and avoid having to do a replacement.

We are really excited to see how it goes

(GSB-88® performs)!

Director of Franklin County Conservation

Dear Mr. Gee
I want to thank you and your staff for the many years of quality service you have provided Iowa State University. We sincerely appreciate your efficient, gracious customer service, and level of detail and accountability you have demonstrated on each project.


Jon Kline and Ross Edgerton stopped in yesterday to discuss scheduling this year’s parking lot maintenance. I’m looking forward to spring when I can visit with Jon and Ross again. They’re always flexible and willing to work around our ever so changing schedules.


I inquired with Ross if we would have the same crew as last year, he assured me Myles and his crew would be returning to ISU. Last summer I visited with Myles daily; he was always courteous, going above and beyond to make adjustments on the fly so everything ran as smooth as possible. I look forward to working with Myles again this summer.


You have a great bunch of people working for you. We are very appreciative of your assistance and are looking forward to continuing our work together.
