Dear Roadware,
“I am writing this letter in regards to Roadware Incorporated, in particular their 10 minute mender concrete repair product. I have been involved in the concrete industry for 28 years. I am a former Certified American Concrete Institute field testing technician and have been an ACI Concrete Flatwork Finisher and Technician for more than 10 years. For the past 15 years, I have been working to perfect the art of concrete rehabilitation on structural concrete and Architectural concrete. Other repair textures include masonry, slate. granite, clay artworks and architectural stone works.At the 2011 World of Concrete Convention, I met with The Roadware sales staff. I was quite intrigued and impressed with their 10 minute concrete mender product line. I was given some test samples which ultimately persuaded me into using Roadware product.
Our first project using Roadware products was a complicated repair contract with a bus transit authority and I had to include a two-year warranty. There would be limited time access during the repair and I needed a product that would withstand heavy bus traffic within hours of application. I submitted my bid using the specifications and MSDS for the 10 minute mender product line and believe this may have been the reason I was awarded the job. End result 10 minute mender works! Fractured concrete, spalled concrete, cracked concrete. Concrete deficiencies e.g. all surface and deep restoration repairs. Microdoweling works period! 

While I was confident in the product, it is always reassuring to experience it first hand. I am quite familiar with what it takes to provide world class service to demanding customers. Roadware Employees deliver excellent customer service and unmatched product support.”

Sincerely,

Repairing vertical cracks in concrete structures with Roadware 10 Minute Concrete Mender™.

The same Microdoweling™ properties of Roadware 10 Minute Concrete Mender™ that make the material excellent for repairing horizontal surfaces also make a good choice for vertical repairs.

Roadware 10 Minute Concrete Mender™ is a very low viscosity polyurethane that uses a surface tension one-third of water to penetrate quickly and deeply into concrete cracks. The typical process relies on self-gravity injection to fill cracks completely. What is not seen by the naked eye is the capillary action of the Concrete Mender polymer chains flowing horizontally into the sideswalls of the crack.  We call this chaining of polymers into the concrete Microdoweling™.  This chaining of the concrete together works on vertical surfaces too.
So, your saying, “How do we get this super thin material to stay in place long enough for the Microdoweling™ to take place and the repair to cure?” Over the years, Roadware contractors have come up with creative and ingenious ways to use Roadware 10 Minute Concrete Mender™ on vertical surfaces. Here are some techniques that have evolved.
1.     Vertical Crack Injection
This technique involves covering the vertical crack with transparent duct tape and injecting Concrete Mender through the tape with a needle tip meter/mix cartridge. This method will work well if the concrete surface is smooth and the tape can make a good bond with the surface. The crack should be 1/4 inch (5mm) or less in width. The tape will make the, “form” while the Concrete Mender sets. Concrete Mender will not stick to duct tape, so once the material cures, you can cleanly pull off the tape. It is best to warm the cartridges up to 80° F (26°C) before use for a faster gel time. Start filling the crack at the lowest point and work you way up.
See the video here.
2.     Bulk Mix and Trowel Applied Repair
Mix bulk Concrete Mender and 60-80 grit manufactured sand into a thick mortar. Working in small batches, use a margin trowel to make the repair. The fine sand will hold the Concrete Mender in place long enough for the Microdoweling™ effect to take place and for the material to set.
3.     Bag Mix and Apply
This method uses a heavy duty, clear plastic bag to quickly mix one part of blended Concrete Mender to two parts of 60-80 grit manufactured sand. Once mixed by kneading the bag for several seconds, the bag is opened and the whole batch is applied and held in place with the bag. This technique is used around building mechanical entry points such as refrigeration and HVAC units.
Whatever method you choose, Roadware 10 Minute Concrete Mender™ stands at the ready to perform. Finished repairs can be ground smooth and painted to match the wall if necessary.

Polishing un-polishable Concrete

Polishing and honing concrete to smooth shiny surface is a great way to give an old warehouse floor new life. Sometimes, warehouse floors are too damaged and worn to make polishing practical. Floors that are full of cracks and spalls will require a large amount of grinding and polishing to achieve an acceptable surface. Roadware 10 Minute Concrete Mender™ may be used to restore the concrete surface and reduce the time and expense of heavy grinding. The Microdweling™ action of Roadware 10 Minute Concrete Mender™ can penetrate the surface of the cracks and spalls, fill in all the low spots, and make the floor ready for polishing.

Pitted, spalled and cracked surfaces may be unpractical to polish.

 

The first step is a light surface grinding to open up the cracks and remove any loose materials.

An initial grinding with metal resin pads reveals cracks and spalls.

Roadware 10 Minute Concrete Mender™ and fine silica sand mixed in bulk is troweled into the surface over the entire area and allowed to set.

Workers trowel Concrete Mender into place.

In about 10 – 30 minutes, the surface is polished using standard techniques. Roadware 10 Minute Concrete Mender™ will not gum-up polishing pads or smear into the surrounding concrete.

After grinding, all pitting, cracks and spalls are filled and a smooth surface is quickly restored.

Concrete Mender repairs hold up perfectly during the polishing process.

Repairing Railings and Posts with 10 Minute Concrete Mender™.

How often have you run into this problem?  Industrial railings that have been split apart due to age, abuse, or weather damage. With a few special techniques, you can repair these problems with Roadware 10 Minute Concrete Mender™.

Clean the repair area with a wire brush or by sandblasting. Remove as much of the rust as possible. It is also a good idea to spray the the steel railing with a rust neutralizer.

 

Make a simple form out of blue foam board, and duct tape or most anything plastic. Do not use wood, Concrete Mender will permanently bond the wood to your railing base.I made that mistake years ago and had to chip, grind and sand the wood off the face of the concrete.

Make your repair by pouring 10 Minute Concrete Mender™ bulk mixed with sand in from the top. Allow to cure and finish the surface with a stone or grinder.

 

Add a quick coating of a latex cement coating and your finished. You may also make repairs around railings with Roadware Flexible Cement II™ if the railing is made aluminum and requires more thermal contraction and expansion properties.

Earthquake Crack Repair at Hope Alive Clinic in Haiti

“Kelton,

In March, you donated the Roadware kit to bind the cracks at the Hope Alive! Clinic in Haiti. THANK YOU FOR YOUR GIVING AND KIND HEART.

We went to the Atlantic City airport with the msds. They refused to allow us to bring the tubes on the plane. (they really didn’t know how to read the msds sheets either)

Anyway, we shipped the package via Philadelphia-container-Haiti. It arrived in time for our July 8th trip.

We brought along a Pastor who is also a “concrete guy”. He stated that he had never worked with a product that was so easy and did such a great job. As you can see in the attached photos, the fissure is completely sealed. As I mentioned in our phone conversation, the epi-center of the quake was only 6-7 miles from our clinic. We even have 2 sets of tubes left over!! (the neighbors will benefit)

I do not know how to say thanks but to just say “thanks” . Your kindness has made a difference with Hope Alive Clinics and the Haitian people. visit www.hopealiveclinic.org for more pictures of the teams and clinic activities.

If you are ever in the Philadelphia area, please look us up.

Again, many thanks and God bless you and your great company.

Making Cracks Disappear

One question we get asked all the time is if we can make a crack disappear.  For the most part the answer has always been no. We can make a good repair and finish it as close as we can to the original color and surface texture. That was before Roadware MatchCrete™ Clear came along.  The photos below were sent in by a concrete polishing contractor. By using MatchCrete™ clear and sand that matches the surrounding concrete, the polished repair blends in very nicely with the concrete slab. When the floor is in service, you will have to look very carefully to find the repairs.  Try some Roadware MatchCrete™ Clear on your next polishing job. With a little technique and experimentation, you can get results like this.
