Here is a crack repair project at the CVG Airport in Cincinnati, Ohio. The upper terminal deck developed cracks parallel to the construction joints. Roadware Flexible Cement II™ was used to repair the cracks in 2005. Here are some pictures of the project over the years.
Here is a photo of the CVG terminal deck as of June 2010.

Roadware Flexible Cement II™ was used the repair the crack on the right in 2005. The crack on the left was repaired with Roadware 10 Minute Concrete Mender™ for comparison.

Finished repairs in 2005. Roadware Flexible Cement II™ on the left. Roadware 10 Minute Concrete Mender™ on the right.

Repairs as they appeared in 2006 after one year of service. Both are holding well. The Roadware 10 Minute Concrete Mender™ on the right shows yellowing, but is still performing well. The Flexible Cement II™ is slightly lighter on color, but looks perfect.

Here is the same repair in June 2010. After 5 years on service, everything looks good.

This is a close-up shot of the Flexible Cement II™ after 5 years of service. The repair is still holding like the day it was installed. Roadware Flexible Cement II™ is a good choice for outdoor repairs in structural concrete. The semi-flexible properties strike a good balance between road toughness and just the right amount movement absorption.
