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.

Repair polished concrete with Concrete Mender™

Stop repairing polished concrete with polyurea joint fillers. They look like plastic, do not bond well, and do not hold-up over time. Concrete polishing lets the natural beauty of stones, sand, and rock shine through.  Your repair product should as well.

We took the proven Microdoweling™ properties of Roadware 10 Minute Concrete Mender™ and combined it with natural sands, aggregates and pigments to make repairs that not only look great, but perform better than epoxies and polyureas.

The repair pictured above shows  Roadware Concrete Mender™ Off-white blended with plain concrete sand and a small amount of portland cement. This water-thin polyurethane is almost translucent. When we add nearly any type of dry sand or aggregate, we get a fast-curing polishable repair that blends beautifully with the surrounding concrete. Since this material is almost translucent, it resists shadowing effects due to over-banding when applied.

Extreme Concrete Repair and Polish

How do polish a floor when your concrete is like this?

Deep cracks and surface spalling can make polishing jobs costly and difficult.  A lot of the top surface has to be removed to get to a smooth finish.

Roadware 10 Minute Concrete Mender™ is a great choice for filling out all the cracks, spalls and holes before polishing.

This floor was repaired by troweling down a thin layer of Concrete Mender and sand, then ground smooth. A liquid hardener completed the restoration and the floor was polished.

 

The floor shows zero failure shown here 3 years later in 2007.  The floor continues to perform today.

Repairing Cracks in Driveways and Patios Updated

One of the most common calls we get is asking how to repair a crack in a driveway or patio.  We designed Roadware MatchCrete™ Clear with this in mind.  Roadware MatchCrete™ Clear is a UV stable clear polyurethane hybrid that makes effective repairs to most exterior concrete surfaces.  By simply leaving the repair clear, the color of the surrounding concrete shows throughout the repair.

The first step to a good looking crack repair is to rout-out or cut the repair open with a diamond blade grinder.  You only have to go about 1/4″ x 1/4″. This will create a recess for the material to rest as it soaks down further into the crack.  Skipping this step will allow the material to flow uncontrollably on the surface and will create a messy looking repair.

 

Apply cartridge mixed MatchCrete™ Clear directly to the crack. Small amounts of silica or quartz sand can be added to keep the material from flowing out the bottom of the slab.  If necessary, matching colored sand can be used to match colored concrete areas. Fill the crack to slightly below grade to prevent material from flowing on to the surface of the concrete.

After a year of service, the repair above still looks good.  Please note, MatchCrete™ Clear is not a soft expansion joint material and should not be used in joints that are designed to move.  Always give careful consideration as to why the concrete cracked in the first place and what the concrete is expected to do in the future before making repairs of this nature.
