New Freezer Floor Coating Stops Concrete Dusting

Leave a comment

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.

Amazon Warehouse – Full depth crack repair without sawing.

3 Comments

Full depth crack repair in warehouse floors usually involves cutting open the cracks with dry diamond saws. This is a slow process and creates a lot of hazardous silica dust that needs to be mitigated. Repair contractors at an Amazon Warehouse project are using an innovative way to repair cracks in the floor without the traditional cut and fill methods. 

The problem:

Some people question why these types of cracks should be repaired. Cracked floors in industrial and commercial settings are a liability.  The cracks will continue to get larger as wheeled traffic starts to crush the sidewalls. (More) Cracks will also fill with dirt and debris creating a hard to clean surface. Roadware 10 Minute Concrete Mender™ is a structural polyurethane that will restore load transfer and can bring a floor back to original serviceability. 

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:

Use sacrificial vinyl weatherstrip to make a dam parallel to the cracks that will hold Roadware 10 Minute Concrete Mender™ in place while it soaks down into the cracks. Concrete Mender™ is nearly water thin when mixed and will flow easily deep into open cracks. Since Concrete Mender™ will start to gel up in 5-7 minutes, it will naturally self-seal the bottom of the crack as it cures. It sometimes takes three of four light pours of material, but it will fill the crack completely and start the structural Microdoweling™ process. Microdoweling™ is how Concrete Mender™ uses low surface tension and molecular attraction to penetrate concrete surfaces and locking into the aggregate and rock matrix.

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 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.

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 Leave a comment

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.

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

43 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 not worth the trouble fixing. Did you know that just about every crack in concrete started out as a hairline crack? Some so fine, you can not even see them with the naked eye. Cracking naturally occurs in concrete slabs as the concrete cures and shrinks. We use saw cut control joins to encourage the concrete to crack inside the saw cut or tooled joints. The problem is, the concrete doesn’t always listen and can crack where it wants to crack. We don’t like it, but that’s just the way it is. The truth is, we would fix hairline cracks if there was a good and efficient way to do it. Most of the time, we ignore hairline cracks and blame them on the nature of concrete and say things like, “It will be fine, you still have aggregate interlock and the crack is just on the surface.” Or, “All concrete cracks, and its just the nature of the product… Check out our new floor covering selection.” The customer, who just invested in a new concrete floor, is never happy with these explanations.

The truth is, we would fix hairline cracks if there was 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 this for over twenty years.

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

Roadware Easy Injection mixers make getting Concrete Mender into cracks as small as 20 mil (0.02 inches) simple. Just drill a 3/8 inch  hole into the crack and push the nearly water thin Concrete Mender into the cracks. You can actually watch  the Concrete Mender flow along the length of the hairline crack. Leave the expensive injection pumps in the shop. A cartridge of Concrete Mender and a manual application gun is all you will need.

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.

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

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.
