Amazon Warehouse – Full depth crack repair without sawing.
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.
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.
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.
Application:
With Concrete Mender™, expensive pumps and equipment is not needed. Once cracks are vacuumed and the surface is cleaned. The weatherstrip dam can be applied. Roadware 10 Minute Concrete Mender™ can be mixed on one gallon batches by hand in a bucket and poured directly into the cracks. Additional manufactured sand can be added for larger cracks, but it is not recommended for this type of repair. See more here: Concrete Mender Bulk Application Instructions
When the Concrete Mender™ cures in about 10 Minutes at 72 degrees F (21C) , the weather stripping and excess material can be shaved clear or ground smooth with standard equipment.
After buffing and clearing excess material, floors can be returned to service immediately.
Finished concrete crack repair blend in nicely at an Amazon warehouse using full depth Roadware 10 Minute Concrete Mender™.
Additional buffing and service traffic will blend the repairs even more into the surrounding concrete.

Smart floor repairs for AGV’s and warehouse robots.
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.
- 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.
- 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.
- 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.

Bridge crack repair in the Philippines.
Make Roadware 10 Minute Concrete Mender part of your bridge preventative maintenance program. Repair cracks as they develop when they are small. Don’t let small cracks turn into big problems. Roadware 10 Minute Concrete Mender™ is extremely tough and will withstand even the harshest punishment. Use all year long… may be applied at temperatures as low as -20° F with excellent results.
Roadware 10 Minute Concrete Mender is great repairing surface cracks in a bridge deck. The flow-and-go application along with the 10 minute cure time allow repair crews to get on and off the bridge quickly. Traffic can be returned to the bridge in just 10 minutes after application. In the Philippines, crews often work at night when traffic is low and working conditions are cooler.
Crews work in teams. One person shoots the Concrete Mender from 600ml cartridges, one person applies filler sand, and one person trowels the repair smooth.

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.
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.
- 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).
- 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.
- 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.
- 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.
- Once the crack is filled to refusal, move on to the next few drilled holes until the whole crack is filled.
- 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.
Using Roadware 10 Minute Concrete Mender and Soft-tip injection mixers, you can structurally repair concrete cracks and delaminations with simple tools and methods. This unique system saves time and money and allow for a high production rate for installers. The drill hole/inject method is much less invasive than traditional cut and fill methods and creates a lot less silica dust on the jobsite. The Microdoweling properties of Concrete Mender and Soft-tip Injection promises to be a winning combination for tough concrete repair challenges.
*“Workers may be exposed to dangerous levels of silica dust when cutting, drilling, grinding, or otherwise disturbing materials that contain silica. These materials and tasks are common on construction jobs. Breathing that dust can lead to serious, often fatal illnesses.” The Center for Construction Research and Training.

** 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.
Swimming Pool Repair with Concrete Mender
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.
Roadware 10 Minute Concrete Mender is flooded into the spalled ares and seeded with manufactured sand.
The Concrete Mender and sand bland can be troweled in place and will cure in about 10 minutes.
Vertical surfaces can be repaired by mixing Concrete Mender with fine manufactured sand and troweled in place.
