Smart floor repairs for AGV’s and warehouse robots.

1 Comment

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.

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

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.
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

Image 2 Comments

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. 

Automotive lift floor attachment patten over existing list installation.

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.
Roadware 10 Minute Concrete Mender, sand, mixing buckets, and mixing sticks.

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.

New Full-depth Hairline Crack Injection Breaks the Rules

52 Comments

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.

What are the reasons DOT’s Roadware?

1) “Safety for the driving public.” Roadware repairs are ready for traffic in 10 minutes. Lane closure time is dramatically reduced.

2) “Safety for my crew.” The interstate is a dangerous work environment, the quicker repairs are made, the less exposure to the hazards of working on a heavily traveled interstate.

3) “Saves a lot of money.” Quick cure times, easy mixing, straight forward application, and good long term performance makes Roadware 10 Minute Concrete Mender a good value. After a few days of training, the crew was able to repair a bridge in half a day. One district in Wisconsin saved about $1500 per bridge over conventional repair methods. No overnight lane closures are needed and crews are more productive with less equipment requirements.

Full Depth Crack Injection with Concrete Mender.

11 Comments

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.

** Structural Polyurethane: A polyurethane based material that restores structural integrity and aggregate interlock to distressed concrete by using low surface tension and low viscosity to penetrate concrete surfaces and cross-linking polymer chains to bond directly to the concrete-aggregate matrix.  This bonding action utilizes capillary forces to self-inject polymer chains into the surrounding concrete. This material should have a modulus of elasticity less than the surrounding concrete and should not become brittle over time. This material may be combined with manufactured sand to form a PCC compatible polymer concrete that can structurally repair concrete cracks  and spalls.

What do you do when your pool has cracks and spalls and it has to be open is three days? Back in 2001, the City of South Saint Paul, Minnesota had a problem with their new splash pool. Just before opening the pool for its second season, cracks and spalls were discovered in the concrete pool bottom and along corner where the floor meets the wall. The damaged was probably caused by the first Minnesota winter for this neighborhood splash pool facility. The repairs needed to be done fast. The pool was scheduled to be open in just three days. Any delay would be a disappointment for local families and political problem for the City who spent a lot of money to build this water recreation facility.

The call went out to see if anyone could come up with a solution. Roadware Incorporated, also located in the City of South Saint Paul, received a call from the Parks and Recreation Maintenance Department to see if we had any ideas. It turns out, Roadware 10 Minute Concrete Mender™ is a great product for repairing concrete pools. The cross-linked polyurethanes in Concrete Mender and very resistant to water, chlorine and other pool chemicals.

Roadware personnel were at the pool within a few hours and repairs were made using a mixture of Roadware 10 Minute Concrete Mender and manufactured sand.
