How an Amazon Warehouse uses Concete Mender to repair cracks with no-cut full depth crack repair.

Repairing full-depth cracks in warehouse floors typically requires cutting open the cracks with dry diamond saws. This process tends to be slow and produces a significant amount of hazardous silica dust that must be managed carefully. However, repair contractors working on an Amazon Warehouse project have adopted an innovative method to address cracks in the floor without relying on traditional cut-and-fill techniques.

The problem:

Some people wonder why it’s important to repair cracked floors. In industrial and commercial environments, these cracks can become a liability. As wheeled traffic moves over them, the cracks will continue to expand, causing further damage. Additionally, cracks can accumulate dirt and debris, making the surface difficult to clean. The Roadware 10 Minute Concrete Mender™ is a structural polyurethane designed to restore load transfer and can help bring the floor back to its original condition.

Thre level Amazon Warehouse with cracks in the floor.

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.

 

Crack in warehouse floor.
This floor presented thousands of feet of shrinkage and stress cracking. The cracks were all fairly clean without excessive foreign debris or dirt at time of repair. 

 

The Plan:

 

To repair the cracks, we will use sacrificial vinyl weatherstrip to create a dam alongside the cracks. This will hold the Roadware 10 Minute Concrete Mender™ in place while it seeps down into the cracks. When mixed, Concrete Mender™ has a water-thin consistency, allowing it to flow easily into open cracks. Since it begins to gel within 5 to 7 minutes, it will naturally seal the bottom of the crack as it cures. It may require three or four light applications, but this will fill the crack completely and initiate the structural Microdoweling™ process. Microdoweling™ is a method by which Concrete Mender™ utilizes low surface tension and molecular attraction to penetrate concrete surfaces, locking into the aggregate and rock matrix.

Application:

With Concrete Mender™, there’s no need for expensive pumps and equipment. First, vacuum the cracks and clean the surface. Then, you can apply the weatherstrip dam. Roadware 10 Minute Concrete Mender™ can be mixed by hand in one-gallon batches using a bucket, and it can be poured directly into the cracks. While additional manufactured sand can be added for larger cracks, it is not recommended for this type of repair. For more details, see the Concrete Mender Bulk Application Instructions.

Pour equal parts A and b into a mixing container and mix for about 15 seconds with a mixing stick.

New Full-depth Hairline Crack Injection Breaks the Rules

1006-STR Roadware Easy Injection static mixer for Roadware 10 Minute Concrete Mender 600ml Cartridge.

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.

Broken Rule One
 Hairline cracks are not worth the trouble fixing.

Broken Rule Two
 You have to cut open a hairline crack if you want to actually repair it.

Broken Rule Three
Crack injection requires pumps, ports, slow epoxy, and lots of time.

Let’s look at these “rules” one by one. 

Broken Rule One: Hairline cracks are often dismissed as not worth fixing. However, it’s important to note that almost every concrete crack starts as a hairline crack. Some of these cracks are so tiny that they are not visible to the naked eye.

Cracking naturally occurs in concrete slabs as the concrete cures and shrinks. We use saw-cut control joints to guide the concrete to crack inside the designated joints, but sometimes the concrete cracks in unexpected places. We wish there were an efficient way to fix hairline cracks, but for now, we generally ignore them and attribute them to the nature of concrete. We might reassure customers by saying, “It will be fine; you still have aggregate interlock, and the crack is just on the surface,” or “All concrete cracks, and it’s just the nature of the product.” Unfortunately, customers who have invested in a new concrete floor are usually dissatisfied with these explanations.

The truth is, we would fix hairline cracks if there were a good and efficient way to do it.

Scoring a concrete crack with a diamond grinder.

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 it for over twenty years.

What is needed is a way to actively push repair products into hairline cracks. Roadware 10 Minute Concrete Mender can do the job with simple techniques and Easy Injection Mixers. 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:

  • Delivery of materials to the repair area.
  • The repair material needs to set before if flows away from the repair area .
  • The repair has to be structurally effective.

The Roadware Easy Injection mixers make it easy to fill cracks as small as 20 mil (0.02 inches) with Concrete Mender. Simply drill a 3/8-inch hole into the crack and then push the almost-water-thin Concrete Mender into the cracks. You can see the Concrete Mender flow along the entire length of the hairline crack. You won’t need expensive injection pumps for this – just a cartridge of Concrete Mender and a manual application gun.

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.

Full Depth Crack Injection with Concrete Mender.

A 24″ deep core sample shows 100% injection repair with Roadware 10 Minute Concrete Mender.

For many years, engineers have looked for ways to fully inject repair polymers into cracked concrete structures. The general consensus is to seal off the crack with a sacrificial epoxy and install injection ports every few inches. Then thick epoxy is injected under high pressure into the crack with expensive resin injection pumps. The process is time-consuming, the epoxy is brittle, the equipment is expensive and the skill level is highly specialized. This makes epoxy injection slow, expensive and not really effective in the field.

At Roadware, we look for ways to make concrete repair fast, effective and easy.  

Fast is better. When injecting Roadware 10 Minute Concrete Mender into concrete, the fast gel and cure time allows you to make a full depth repair from the bottom of the crack up to the top. If the crack you are injecting has a large hidden void, Concrete Mender repairs will start to gel and plug up the void in several minutes. Injection epoxy that takes several hours to cure will sink to the bottom of your crack and pool in the base before it has a chance to cure.

Effective. Concrete Mender is a Structural Polyurethane**.  It is about as hard as typical concrete with much greater tensile and bonding strength. It is super thin at 8cps with a surface tension 1/3 of water. It can to penetrate concrete cracks and surfaces. Concrete Mender does not need to be forced into cracks with high pressure pumps and extraordinary methods.  Concrete Mender can easily flow into cracks and fissures with just simple manual tools and a specially designed application mixer. You can repair more cracks in less time with less waste then ever before. Repairs are structural in nature and will move with the concrete, not against it like very hard epoxies.

Easy Application. For a repair to be effective in the field, it has to be simple enough for crews to apply efficiently. Installation productivity saves money.

Diagram showing Concrete Mender Soft-tip mixer injection into a concrete slab.

  1. To start, simply drill a 3/8″ diameter hole about one inch deep into the crack at several points along the crack. Clean the crack and holes with a vacuum.* (Click here to learn how to work safely around silica dust).
  2. Tape off the top of the crack and around the holes you just drilled with clear duct tape or Gorilla Clear Repair Tape. These tapes have a good adhesive that will stick to the surrounding concrete. Do not use packing tape or other tapes without testing them first.
  3. Assemble a cartridge of Roadware 10 Minute Concrete Mender using out specially designed Soft-tip static mixer. Purge the cartridge of air as directed and insert nozzle into the first hole you drilled earlier.
  4. Gently squeeze the handle of the gun and slowly inject Concrete Mender into the crack. Work product into several holes at a time, moving the cartridge back and forth among them. Allow time for  the Concrete Mender to start gelling in the bottom of the crack.  As the crack starts to fill completely, you will see Concrete Mender flow under the clear tape from one drilled hole to the other. You may see air bubbling up from one hole as you inject Concrete Mender into adjacent holes.
  5. Once the crack is filled to refusal, move on to the next few drilled holes until the whole crack is filled.
  6. After 10 minutes at 70 degrees or 23 C, pull the tape. You can use a razor scraper, grinder or polishing device to remove and excess material and blend in the repair.

Polished Concrete Floor Repair | Roadware 10‑Minute Concrete Mender™ for Cracks, Spalls & Joints

Concrete Floor Polishing & Repair: Why Roadware 10‑Minute Concrete Mender™ Is the Industry Standard

Large commercial buildings—big‑box retailers, airports, warehouses, logistics centers, and convention halls—have made polished concrete floors one of the fastest‑growing flooring categories in the world. Facility managers and contractors now prefer polished concrete for its:

  • Clean, modern appearance
  • Low maintenance requirements
  • Dust‑free, smooth surface
  • High light reflectivity and energy efficiency
  • Long‑term durability under heavy traffic

But before any concrete floor can be polished, every crack, spall, joint failure, and surface defect must be repaired correctly. Poor repairs lead to failures during grinding, callbacks, and costly downtime.

Why Pre‑Polish Concrete Repair Matters

Polishing equipment places extreme stress on the slab. If the repair material cannot bond, flex, and carry load, it will:

  • Pop out during grinding
  • Smear or melt under heat
  • Disbond under forklift traffic
  • Create visible defects that ruin the finish

This is why professional polishing contractors rely on high‑performance structural repair materials, not patching compounds.

⭐ Contractor Spotlight: C&C Construction Co.

“Concrete Mender™ eliminates the anxiety of repair failure.”

Curtis Venable, president of C&C Construction Co., has polished millions of square feet of concrete. His rule is simple:

“Cracks, spalls, and joints must be repaired correctly. Poor repairs undermine my credibility and cost everyone time and money.”

While Venable uses different materials depending on the job, he frequently chooses Roadware 10‑Minute Concrete Mender™ for its speed, strength, and reliability.

⭐ Why Contractors Choose Roadware 10‑Minute Concrete Mender™

1. Microdowling™ Technology = Permanent Structural Bond

Concrete Mender™ is an ultra‑low‑viscosity polymer that penetrates deep into micro‑fissures, creating a structural bond stronger than the original concrete. This Microdowling™ action allows repairs to:

  • Transfer load without cracking
  • Absorb shock from forklifts and heavy equipment
  • Resist chemicals and moisture
  • Perform in extreme temperatures, including freezers

“I know it won’t melt, smear, or come out when my polishing machines run over it,” Venable says. “Some of our repairs are 6–7 years old and still perfect.”

2. 10‑Minute Cure Time = Maximum Productivity

On large polishing projects, downtime is expensive. Concrete Mender™ cures in about 10 minutes, allowing crews to:

  • Repair
  • Grind
  • Polish
  • Keep machines moving

Venable recalls a 110,000‑square‑foot national grocery retailer project:

“With six people on polishing machines for three weeks, waiting for repairs to cure is not an option. Concrete Mender keeps the job moving.”

3. Repairs That Blend Seamlessly With Polished Concrete

Retailers demand clean, uniform floors—no mismatched patches or visible repairs. Concrete Mender™ blends naturally with surrounding concrete, producing a near‑perfect color match after polishing.

“A patchwork of colors is unacceptable today,” Venable explains. “Repairs must blend into a single, clean finish.”

  • Permanent structural bonding through Microdowling™
  • 10‑minute cure time for maximum efficiency
  • Polishable, cuttable, grindable performance

Smart floor repairs for AGV’s and warehouse robots.

“If your AVG could talk, it would ask for Concrete Mender. ” Richard King, Roadware, Inc.

Keep your robots moving. Keep your floors performing.

AGV carrying beer on a preset path in a warehouse.
AGV’s move thousands of pounds in a single trip over the exact same path hundreds of times per day.

Automated Guided Vehicles (AGVs) and warehouse robots are the backbone of modern distribution centers. They run the same routes thousands of times per day—quietly, efficiently, and relentlessly. But their small, hard wheels can be brutal on concrete floors.

Over time, those repeated passes crush joint edges, wear down surface paste, and create ruts, spalls, and dusting that slow down operations and damage equipment.

Roadware 10 Minute Concrete Mender with Microdoweling™ delivers the only repair solution engineered to move with the concrete, bond deep into micro‑fractures, and stand up to the punishing traffic patterns of AGVs.

Why AGV Floors Fail — and Why Traditional Epoxies Make It Worse

AGVs concentrate thousands of pounds of load onto narrow wheel paths. When they repeatedly cross control joints and worn concrete, the damage compounds:

  • Joint shoulders crumble
  • Surface paste turns to dust
  • Ruts form in high‑traffic lanes
  • AGV drive systems and wheels wear prematurely

Many facilities try to fix this with brittle, high‑PSI epoxies. But that creates a new problem:

Hard epoxy + softer concrete = speed bumps and pop‑outs.

If your concrete is ~4000 psi and you patch it with a 10,000+ psi epoxy, the epoxy won’t flex. The surrounding concrete continues to wear, leaving raised, rigid epoxy “islands” that fracture at the bond line.

The Concrete Mender™ Advantage: Tough, Flexible, and AGV‑Ready

Roadware 10 Minute Concrete Mender® is engineered differently:

  • Microdoweling™ penetration bonds deep into the concrete matrix
  • Modulus of elasticity slightly below concrete allows repairs to flex under load
  • Repairs wear with the concrete, not against it
  • No brittle failures, no speed bumps, no pop‑outs
  • Traffic-ready in about 10 minutes — even under heavy AGV loads
  • Works in freezers down to –30°F

Your AGVs get a smoother path. Your floors last longer. Your maintenance team stops chasing recurring failures.

Fast Repairs. Minimal Downtime. Maximum Uptime.

Closing aisles for hours or days is expensive. With Concrete Mender®:

  • Minimal prep
  • Fast cartridge or Easy Injection application
  • Return to service in minutes
  • Ideal for 24/7 operations, cold storage, and high-throughput facilities

AGVs can stay productive — and so can your team.

Where Concrete Mender Excels

  • Control joint rebuilding
  • Spall and pothole repair
  • Wheel-path ruts
  • Cracked or delaminated concrete
  • Freezer and cold‑storage floors
  • High‑traffic robotic lanes

If your AGVs follow the same path every time, Concrete Mender® keeps that path smooth, durable, and reliable.

Recommended Products for AGV Floor Repairs

Your AGVs Will Thank You

As Roadware’s Richard King says:

“If your AGV could talk, it would ask for Concrete Mender.”

Because smoother floors mean fewer breakdowns, less wheel wear, and more uptime.

Concrete repairs for AGV’s need to bond under heavy traffic as well as deflect with the concrete and transfer loads to the surrounding concrete without fracturing.

AVG’s like to take the same path every time. This can prematurely wear out concrete floors.

Quick Concrete Solutions for Bridge Maintenance

Bridge maintenance crews in West Virginia are using Roadware 10 Minute Concrete Mender to repair hairline cracks in bridge decks. Concrete Mender is a high-performance, rapid-curing concrete repair product designed to restore structural integrity and prevent further deterioration. It is specially formulated to bond well with existing concrete and withstand harsh environmental conditions. Applied with 600 ml dual cartridges and a needle tip mixer, Concrete Mender allows for precise application and minimal waste. The product’s quick curing time of just 10 minutes facilitates rapid reopening of traffic.

Before application, cracks are lightly scored with a diamond blade to ensure proper bonding. Dust and dirt are removed to achieve a clean surface. Concrete Mender is then applied to the top of the crack and allowed to soak in, creating a strong, durable seal. Silica sand is sprinkled onto the wetted surface to enhance bonding strength and surface texture. The material is allowed to cure for 10 minutes, after which traffic can resume immediately, reducing downtime and maintaining safety.

Spall Repair with MatchCrete™ Clear

Using Roadware matchCrete Clear, cement powder, and rock to make exposed aggregate concrete spall repairs. 

 

This driveway was seriously damaged from deicing snowmelt treatments. I simply routed out the perimeter of each of the damaged areas. I then thoroughly power washed to remove all dirt and loose debris and allowed the area to dry. I mixed up four separate batches of Matchcrete mender with 1/4”pea gravel seeded on top. I then applied a small amount of fine sand before the surface had hardened. The homeowner was extremely pleased with the finished results!! Thanks so much to the folks at Roadware Inc for their insight and positive support on this project!! Please note,
I will diamond cut, and route open the original joints after full cure time.

New Freezer Floor Coating Stops Concrete Dusting

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).

Dusting concrete floors in a freezer can lead to unsafe and unsanitary conditions as well as contamination of product.

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.
