Concrete Mender on the Busan Metro Line 4

The Busan Transportation Corporation uses Roadware 10 Minute Concrete Mender to repair the roll-way of Busan Metro Line 4 in South Korea. Metro Line 4 is a rubber-tired line with 14 stations and runs driverless with pneumatic tires on a 6.7 mile (10.8km) concrete track. Concrete Mender is used to structurally repair the cross joints in the track approximately every ten meters.

Concrete Mender is the right product for the job because it has a long service life and cures in about 10 minutes. This allows for minimal down time and keeps the Busan Metro Line 4 running on time with minimal service interruption.

Repair crews of a very limited repair window, The train operates approximately 20 hours per day from 5am to 1am the next day. That leaves a minimal amount of time for maintenance and repair operations. Crews have to be efficient and productive. The fast cure and rapid strength gain of 10 Minute Concrete Mender is well suited for these mission critical applications.



Having a smoother roll-way saves wear and tear on the rubber tires and reduces operating costs.  Roadware 10 Minute Concrete Mender will keep the Busan Metro Line 4 running smooth and efficiently for years to come.

Stamped Concrete Patio Pop-out Repair

Repairing seasonal pop-outs in stamped and colored concrete is easy with MatchCrete™ Clear. Just add some powered pigment or grout to the clear MatchCrete™ aliphatic polyurethane and you can match most any color. Come back after 24 hours and give the repairs a light sanding to blend them in. See the short video below.

Use Roadware 10 Minute Concrete Mender™ to repair concrete statuary.

In October 2014, Roadware was exhibiting at the Concrete Decor Show in Ft Worth, Texas. After the first day of the show, I received a phone call from an exhibitor working in the Decorative Concrete Competition at the show. A decorative art piece cracked in half as it was removed from its mold. The piece was intended to be a giant leaf shaped chair. The question now was, can it be fixed and would Concrete Mender™ work?

I walked back over the show at the Ft Worth Convention Center and this is what I encountered.

The “Chair” was broken into two parts right at the critical stress point in the middle.
We carefully pushed the two pieces together using care to mate the surfaces as closely as possible and supported the chair with wood 2×4’s and some shims. I then place duct tape on the bottom of the break to hold the Concrete Mender™ in place while it cured.

I used two 50ml cartridges of Concrete Mender and 4030 silica sand to make a full depth repair.

This is how the repair looked when I was finished.

The next morning, we came back and removed the wooden supports and the duct tape. The repair held perfectly. The Concrete Mender has structurally repaired the high strength concrete back together. 

William Reynolds with element7concrete continued with the project by scoring veins in the leaf with a diamond blade.
A high gloss glaze was added to the surface.

You could barely see the break when the glaze cured.

The repair was strong enough the hold together when moving the chair into the exhibit.

The finished work help together for the duration of the show and the move out process after. Roadware 10 Minute Concrete Mender™ with its Microdoweling™ structural bonding really saved the day.
Thank you to William Reynolds with element7concrete in Granite Shoats, Texas for their masterful artistic skills and all their hard work.
Once work got out that I repaired the chair, I was call on to repair other projects at the convention like   this long horn steer.
I use 10 Minute Concrete Mender™ to repair the tip of the horn.

You would never know it was broken.
