Full depth crack repair in warehouse floors usually involves cutting open the cracks with dry diamond saws. This is a slow process and creates a lot of hazardous silica dust that needs to be mitigated. Repair contractors at an Amazon Warehouse project are using an innovative way to repair cracks in the floor without the traditional cut and fill methods.
Some people question why these types of cracks should be repaired. Cracked floors in industrial and commercial settings are a liability. The cracks will continue to get larger as wheeled traffic starts to crush the sidewalls. (More) Cracks will also fill with dirt and debris creating a hard to clean surface. Roadware 10 Minute Concrete Mender™ is a structural polyurethane that will restore load transfer and can bring a floor back to original serviceability.
This three level Amazon Warehouse developed thousands of linear feet of shrinkage cracks prior to being places into service. Roadware 10 Minute Concrete Mender will be used to repair them.
Use sacrificial vinyl weatherstrip to make a dam parallel to the cracks that will hold Roadware 10 Minute Concrete Mender™ in place while it soaks down into the cracks. Concrete Mender™ is nearly water thin when mixed and will flow easily deep into open cracks. Since Concrete Mender™ will start to gel up in 5-7 minutes, it will naturally self-seal the bottom of the crack as it cures. It sometimes takes three of four light pours of material, but it will fill the crack completely and start the structural Microdoweling™ process. Microdoweling™ is how Concrete Mender™ uses low surface tension and molecular attraction to penetrate concrete surfaces and locking into the aggregate and rock matrix.
With Concrete Mender™, expensive pumps and equipment is not needed. Once cracks are vacuumed and the surface is cleaned. The weatherstrip dam can be applied. Roadware 10 Minute Concrete Mender™ can be mixed on one gallon batches by hand in a bucket and poured directly into the cracks. Additional manufactured sand can be added for larger cracks, but it is not recommended for this type of repair. See more here: Concrete Mender Bulk Application Instructions
When the Concrete Mender™ cures in about 10 Minutes at 72 degrees F (21C) , the weather stripping and excess material can be shaved clear or ground smooth with standard equipment.
After buffing and clearing excess material, floors can be returned to service immediately.
Finished concrete crack repair blend in nicely at an Amazon warehouse using full depth Roadware 10 Minute Concrete Mender™.
Additional buffing and service traffic will blend the repairs even more into the surrounding concrete.

Thank you and be safe,
Roadware 10 Minute Concrete Mender™ and Easy-injection mixers make full depth crack repairs in hairline cracks without cutting. This less evasive crack repair technique breaks the rules for concrete repair.
Let’s look at these, “rules” one by one.
Broken Rule One: Hairline cracks are not worth the trouble fixing. Did you know that just about every crack in concrete started out as a hairline crack? Some so fine, you can not even see them with the naked eye. Cracking naturally occurs in concrete slabs as the concrete cures and shrinks. We use saw cut control joins to encourage the concrete to crack inside the saw cut or tooled joints. The problem is, the concrete doesn’t always listen and can crack where it wants to crack. We don’t like it, but that’s just the way it is. The truth is, we would fix hairline cracks if there was a good and efficient way to do it. Most of the time, we ignore hairline cracks and blame them on the nature of concrete and say things like, “It will be fine, you still have aggregate interlock and the crack is just on the surface.” Or, “All concrete cracks, and its just the nature of the product… Check out our new floor covering selection.” The customer, who just invested in a new concrete floor, is never happy with these explanations.
The truth is, we would fix hairline cracks if there was a good and efficient way to do it.
Broken Rule Two: You have to cut open crack if you really want to repair it. A repair material has to actually get into a crack so it will actually do some good. Anything short of that is no better than caulk. For the most part, this is true. We can’t repair what we can’t reach. Traditional cut and cover techniques us a diamond blade saw to open up a crack, forming a shallow well for Concrete Mender to accumulate and flow down into the crack. It works really well and Roadware has been doing this for over twenty years.
What is needed is a way to actively push repair products into hairline cracks. With a few simple techniques and Easy Injection Mixers, Roadware 10 Minute Concrete Mender can do the job. That brings us to:
Broken Rule Three: Crack injection requires pumps, ports, slow epoxy, and lots of time.
For a successful crack injection repair you need to accomplish three things:
Roadware Easy Injection mixers make getting Concrete Mender into cracks as small as 20 mil (0.02 inches) simple. Just drill a 3/8 inch hole into the crack and push the nearly water thin Concrete Mender into the cracks. You can actually watch the Concrete Mender flow along the length of the hairline crack. Leave the expensive injection pumps in the shop. A cartridge of Concrete Mender and a manual application gun is all you will need.
Roadware 10 Minute Concrete Mender starts to thicken and cure in about 5 minutes after application, so the material will stay where you put it. Traditional injection epoxies take hours to cure. In many cases, at the end of the day, the epoxy all ends up under the slab and no longer in the crack.
Roadware 10 Minute Concrete Mender™ with Microdoweling™ penetrates traditional bond lines and repairs concrete from the inside out. This structural polyurethane will not become brittle over time. Epoxy injection resins become very hard and brittle. As the concrete deflects under traffic, the brittle epoxy will start grinding away at the bond-line and the deterioration will start all over again. Roadware 10 Minute Concrete Mender is designed to restore aggregate interlock and deflect with the concrete under heavy traffic and loading. This structural polyurethane will not become brittle over time and is designed to bring the cracked concrete back to original pre-cracked condition.
The Milan-Malpensa MXP International Airport in Ferno, Italy handles nearly 20 million passengers per year and over 500,000 tons of international freight annually. Crews are using Roadware 10 Minute Concrete Mender™ to repair cracks in taxiways. The deep penetration of Concrete Mender and the 10 minute cure helps keep the historic airport running at top efficiency.
Roadware 10 Minute Concrete Mender™ is a tough high penetration polyurethane quickly soaks into small cracks and repairs them before they become big problems.
The MXP Airport saves time and money by repairing cracks early when they are small. The Concrete Mender cures in just 10 minutes. This is perfect for repairing taxiways that have to remain open 24 hours per day.
Crews use Concrete Mender supplied in self-mixing 600ml cartridges to quickly apply material exactly where it is needed. No material is wasted. Manufactured sand is added to extend the product volume and control how much Concrete Mender flows into the crack.
Repairs are ready for airport service in about 10 minutes at 70 degrees F (23C).
A new freezer floor coating developed by Roadware, Inc. can stop concrete dusting and restore freezer warehouse floors. Concrete dusting in your warehouse floor is a difficult challenge. Dusting is when the concrete surface deteriorates to powder due to heavy traffic, improper placement of the original concrete, mix design failure or a number of other reasons. Surface dusting can lead to hazardous conditions for personnel, unsanitary conditions and product contamination. If the concrete is solid beneath the surface, these slabs can be made serviceable with specialized coatings. Coating slabs like this is even more challenging in a working freezer where temperatures are typically -20 degrees F (-29C).
Concrete dusting can lead to the complete breakdown of the concrete wearing surface. Pallet jacks and forklifts can grind down the concrete allowing silica dust to become airborne and causing a health hazard.
Disbonded topping slabs and epoxy coatings can also create a hazardous dusting situation.
Here concrete polishing equipment with metal grinding pads are used to remove the dusting surface of the concrete back to a solid surface.
Hand grinders can also be used to remove the dusting surface. Dust collection systems are used to collect hazardous silica dust.
Roadware Freezer Floor Coating is mixed at a ratio of 1:1:1:
One quart A
One quart B
One quart 4030 grit silica or manufactured quartz sand.
Combined on a pail and mix with a paint stick or 10 seconds. Apply immediately.
Coverage rate shown here is approximately 2.5 Meters Sq per mixed liter.
Keep materials at outside the freezer at about 60-70 degrees before mixing. Floor and air temperatures in the freezer for this project were -4 degrees F (-20C).
A single trowel down application is all it takes to provide a new surface to the concrete and good working floor. Product is applied at freezer operating temperatures. Product cures in several hours depending on the temperature and odor is very slight. Stand-up trowels may be used as well.See craftsmen with Concrete Dr in Seoul, Korea apply Roadware Freezer Floor Coating at -4 degrees F (-20C) . A propane torch is used to remove flash frost just before application.
Full warehouse traffic can resume in 10 hours after application.
Floors treated with Roadweare Freezer Floor Coating are resilient and serviceable once again.

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.
Two post automotive hoists and lifts are generally bolted to the floor using compression anchors. When the lift needs to be replaced, the new anchors can not interfere with the old anchor points. If the old anchor points are too close to the new anchor points, the concrete needs to be replaced before the new lift can be installed. This can close a service bay for a month or more.
With Roadware 10 Minute Concrete Mender, we can remove the old compression anchors, repair the concrete and install new compression anchors without having to replace the concrete.
After removing the old lift, the compression anchors need to be removed. If the original anchor hole was drilled full depth, they can be driven down beneath the floor with a hammer and a punch. If the anchor are not full depth, a core drill is used to remove the anchor.
After drilling, the holes are cleaned and reamed with a reaming bit to roughen up the sidewalls. A shop-vacuum is used to remove all dust and debris. The concrete is than cleaned with alcohol or a similar evaporating cleaner. The holes have to be clean and completely dry before proceeding.
Use duct tape to mask off the holes to be filled with Roadware 10 Minute Concrete Mender™
Gather the materials needed to repair the holes. Roadware 10 Minute Concrete Mender is designed to repair cracks, spalls and holes in concrete. Not just simply fill them. The Microdoweling™ penetration of Concrete Mender into the concrete is a structural repair and can bring the concrete back to original design parameters.
We made a short video to demonstrate the basic technique of filling a core drilled hole in concrete. Concrete Mender doubles in volume when adding sand. All we need to do is fill the hole halfway with Concrete Mender and then add sand to bring it up to the top. Note: In the field it may be impractical to get the bottom of the hole completely dry or clean especially if the hole is full depth into the base material. Simply repair the bottom 1/4 of the hole with Concrete Mender and sand first and allow it to cure before repairing the rest of the hole up to the top.
Measure out equal parts of Side A and Side B Concrete Mender and combine them into your mixing bucket. Mix with a stick by hand for about 15 seconds.
Pour equal parts A and b into a mixing container and mix for about 15 seconds with a mixing stick.
Fill the holes half-way with mixed Roadware 10 Minute Concrete Mender.
Add sand into the hole bringing the Concrete Mender level up to the surface. Make sure all the sand is completely saturated.
Level the surface with a trowel or stick and allow to cure for about 10 minutes at 70 degrees F (21C).
Remove the tape after the Concrete Mender cures and turns grey in about 10-15 minutes.
A finishing rubbing brick is used to quickly bring the repairs flush with the floor.
Holes to anchor the new lift are marked and drilled into the concrete. Time to test the repairs and make sure the repairs will hold the anchors for the new lift.
New compression anchors are installed and torqued to the specified level.
For the repair to be successful, the compression anchor must hold 3000 lbs or 1360 kg for 12 hours without cracking or splitting of the surrounding concrete.
Several anchor were tested. All passed and the lift was installed the next day and placed into service. Roadware 10 Minute Concrete Mender™ is designed to bring most concrete slabs back to original design strength. Repairing anchor holes prior to new automotive lift installation with Roadware 10 Minute Concrete Mender is now the specified choice for two of the largest auto service companies in the United States.
