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.

1. 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.
2. 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.
3. 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.
