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’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.

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.

The drive system in a typical AGV can haul a lot of weight, but the floor needs to be smooth.
Warehouse and AGV floors can be repaired and open for traffic in about 10 minutes after application with Roadware 10 Minute Concrete Mender.

Automotive Lift Anchoring Floor Repair

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.

Using a 2″ core drill to remove existing anchors.

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.

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. 

Items needed:

  • 80020 Two-gallon kit of Roadware 10 Minute Concrete Mender.
  • 4030 grit or similar dry manufactured sand or quartz. Enough to fill the holes.
  • Mixing and measuring pails. One quart paint mixing pails work well.
  • Gloves, safety glasses and PPG as needed.

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.

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.

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 anchor holes are drilled for the new lift next to the repaired holes from the old lift anchors.

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.

An anchor testing device is used to pull 3000 lbs of force on the anchor for 12 hours.

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.
