AGV’s or Automated Guided Vehicles are the reliable workhorses of the modern warehouse. They are designed to run smoothly and predictably all day and everyday. AGV’s are great at repetitive tasks moving freight as needed day in and day out. These repeated trips over the same path can be very punishing to concrete floors. The small hard wheels of an AVG can crush control joint sidewalls and grind the concrete surface to dust. This leads to rough, uneven floors that can cause premature breakdowns of AGV drive systems, wheels, and even damaged freight.
“If your AVG could talk, it would ask for Concrete Mender. ” Richard King, Roadware, Inc.
Roadware 10 Minute Concrete Mender with Microdoweling™ penetrates into concrete surfaces repairs concrete cracks, joints and spalls where others fail. Over the years we have noticed some conditions needed for successful repairs in the path of AVG’s.
Repairs need to be as tough as the concrete itself. But not too tough. Let’s say your concrete is a typical 4000 psi in compressive strength. The AGV wheels are grinding away the surface of the concrete and spalling the control joints. You repair the “bad” sections of the path with fairly brittle 10,000 psi epoxy. Now you have sections of the original concrete and sections of much harder epoxy. As the original concrete continues to grind away, the hard epoxy remains and you just created more speed bumps for the AVGs. Concrete Mender will wear with the concrete and deflect with the concrete under load. Your AVG’s favorite path will be smoother longer.
Stop your repairs from popping out. Did you ever notice common warehouse floor repairs popping out in chunks? This can happen when you put a super hard epoxy patch in a not as hard concrete floor. The epoxy is so brittle that it fractures the bond-line when a load is applied. Epoxy repair products have a modulus of elasticity that is so high, it will fracture the concrete before deflecting under load. Concrete Mender has a modulus of elasticity that is slightly less than concrete so it will deflect with concrete concrete under load and gently transfer load from the repair to the surrounding concrete.
Time is money! Closing down aisles or sections of a warehouse is a disruption for everyone including AVG’s. With minimal prep requirements and less invasive techniques including Roadware Easy Injection, 10 Minute Concrete Mender can have your AVG pathways back in service in minutes, not hours or days. You can even make repairs in operational freezers down to -30F.
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.
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.

Special thank you to International Roadware Distributor Join K&C in Seoul, Korea for submitting this project.
The advances in decorative concrete coating and finishes for patios, sidewalks, driveways and pool decks are amazing. All of these systems have one common element. They are all affected by the condition of the concrete underneath. We recommend and use Roadware Concrete Mender™ Off-white to repair cracks, spalls and surface defects prior to decorative concrete treatments and coatings. Off-white Mender is just like the Roadware 10 Minute Concrete Mender™ except it cures to a neutral off-white color that has less chance of affecting the color of the decorative coatings applied over the repairs. Take a look at the project below.
Here is a church with a spalled and rough looking entrance.
Prior repair materials were removed revealing worn, but sound concret
Roadware Concrete Mender™ Off-white and sand mixed in bulk is applied and troweled smooth. The material appears brown due to the brown colored manufactured sand added to the mix.
Cracks are cleaned and repaired with cartridge applied Roadware Concrete Mender™ Off-white and sand.
After about 15 – 30 minutes, the repairs are ground smooth and flat. The concrete is now ready to accept most types of decorative concrete treatments.
Roadware Concrete Mender™ Off-white is compatible with most high-build overlay or coating systems. It is also recommended by several top coating system manufacturers.
Recently a customer sent me several cut sheets from other manufactures of look-alike concrete repair products and asked me to compare them with Roadware 10 Minute Concrete Mender™. Here is how it played out.
We here at Roadware are familiar with the knock-off and look-alike products you submitted for our review. These products fall into the category of a low viscosity polyurea. Basically, what they have done is modify a standard polyurea joint filler and added a solvent to make it appear as a high-penetration Concrete Mender™-like product. They are all missing the key property and process that makes Roadware 10 Minute Concrete Mender™ unique and superior in overall performance. This process is called Microdoweling™.
Roadware’s Microdoweling™ process uses a proprietary formula of polyurethanes and additives to achieve a measured surface tension of 0.026 N/m. (1/3 of water) Surface tension is a measurement of a liquids ability to break free of its own molecular friction and flow into something else. Microdoweling™ is why Roadware 10 Minute Concrete Mender™ can penetrate easily into a concrete surface under adverse conditions, as is the case in distressed, broken and cracked concrete.
Other advantages for Roadware 10 Minute Concrete Mender™ are:
The lowest viscosity for easier mixing and blending.
Easy, one-step polishing and grinding. This material will not melt, smear, or gum up diamond polishing pads. An excellent parging compound.
Experienced and advanced packaging. Roadware cartridge packaging is reliable and works well in the field.
End-user color blending. New MatchCrete™ Concrete Mender can easily be manipulated into many colors by modifying the sand or adding pigments.
A modulus of elasticity that is slightly less then the concrete so repairs will move with the concrete and not against it.
Needle tip application. A complete system of needle-tip cartridge mixers for pin-point application and hairline crack repair.
It’s all in the data. Roadware backs up the Microdoweling™ process with independent testing data and publishes it on our website, www.roadware.us.
Thank you for continued support and please call us any time if you have any questions.
