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.

Concrete Mender on the Busan Metro Line 4

The Busan Transportation Corporation uses Roadware 10 Minute Concrete Mender to repair the roll-way of Busan Metro Line 4 in South Korea. Metro Line 4 is a rubber-tired line with 14 stations and runs driverless with pneumatic tires on a 6.7 mile (10.8km) concrete track. Concrete Mender is used to structurally repair the cross joints in the track approximately every ten meters.

Concrete Mender is the right product for the job because it has a long service life and cures in about 10 minutes. This allows for minimal down time and keeps the Busan Metro Line 4 running on time with minimal service interruption.

Repair crews of a very limited repair window, The train operates approximately 20 hours per day from 5am to 1am the next day. That leaves a minimal amount of time for maintenance and repair operations. Crews have to be efficient and productive. The fast cure and rapid strength gain of 10 Minute Concrete Mender is well suited for these mission critical applications.

 

 

Having a smoother roll-way saves wear and tear on the rubber tires and reduces operating costs.  Roadware 10 Minute Concrete Mender will keep the Busan Metro Line 4 running smooth and efficiently for years to come.

Operations at the world’s busiest cargo airport run 24/7/365 without stopping. Maintenance crews need a crack and joint repair material that can be applied in a wide range of conditions and be ready for service in minutes. Roadware Flexible Cement II  is a tough polyurethane crack repair material that can be applied at any ambient temperature. It bonds very well to distressed concrete and forms a tough semi-elastic polymer that will withstand heavy airline traffic in about 15 minutes. Crews at HKG airport have relied on Roadware Flexible Cement II to make repairs whenever and wherever needed for over 5 years.
