Use Roadware MatchCrete™ Clear, quartz sand, and portland cement to repair cracks in exterior concrete sidewalks and decks with a broom finish. MatchCrete™ Clear is a non-yellowing polyurethane bland that sets fast, bonds very well and can accommodate exterior conditions.
This week the City of Minneapolis used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface on the Stone Arch Bridge in Minneapolis, Minnesota. The Stone Arch Bridge is unique to the Mississippi River and features 23 arches, is 2100 feet long and 28 feet wide.
The bridge was built by railroad baron James J. Hill in 1883 and served as a working railroad bridge until 1965. Today the bridge is mostly used by walkers and bicyclists. The bridge also hosts many festivals and public events in the summer months.
In preparation for the summer festival season, City of Minneapolis crews used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface. MatchCrete™ Clear is combined with matching rock to repair cracks and restore a consistent walking surface.
The process begins with routing out the cracks with a dry diamond blade
to remove loose dirt and debris. Clean and dry matching stone is placed
into the crack up to surface level.
|Matching stone is added up to the surface level|
Next, two-part blended MatchCrete™ Clear is poured into the repair up to the surface. This fills in all the voids between the stones and seals the crack. MatchCrete™ Clear is a semi-ridged material that will support all kinds of traffic from pedestrians to industrial fork lifts.

See video MatchCrete™ Clear application video below:
Repairs will have a, wet” look for a few months and will naturally dull over time. A clear coat sealing over the entire surface will off-set this effect.

In a few months, Repairs with MatchCrete™ Clear will dull and blend into the surrounding concrete.
|Over time, repairs will become less shiny.|

Google has spent the last few years mapping and photographing roads all over the world. If you know where to look, you can see actual concrete repairs with Roadware 10 Minute Concrete Mender™
The Google Map photo below shows actual bridge deck repairs with Roadware 10 Minute Concrete Mender™ on Interstate 279 in Pittsburgh, PA. See all the lighter colored spots? Each one is a hole or spall filled with Roadware 10 Minute Concrete Mender™. The repairs here are over three years old. Thank you Roadware distributor, Express Polymers, Inc., in the Pittsburgh area for sending this project in.
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 on 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.
