Effortless Full-Depth Concrete Crack Injection with 10 Minute Mender

Leave a comment

Roadware 10 Minute Concrete Mender™ has transformed how contractors, facility managers, and engineers approach full‑depth concrete crack repair. Traditional epoxy injection systems are slow, brittle, and require expensive pumps and specialized labor. Concrete Mender’s ultra‑low viscosity polyurethane and Easy Injection™ Mixers make structural crack repair faster, cleaner, and more reliable—without high‑pressure equipment.

Roadware 10 Minute Concrete Mender and the Easy Injection System for repairing cracks and delaminations.

Why Traditional Epoxy Injection Falls Short

Epoxy injection has been the default method for decades, but it comes with major drawbacks:

  • High-pressure pumps required to force thick resin into cracks
  • Brittle repairs that fail under movement or thermal cycling
  • Slow cure times—often several hours
  • Heavy silica dust exposure from aggressive crack chasing
  • High labor cost due to specialized training and equipment

These limitations make epoxy injection impractical for real-world industrial floors, warehouses, and high‑traffic environments.

Roadware Easy Injection System

The Roadware Advantage: Microdoweling™ + Soft‑Tip Injection

Roadware 10 Minute Concrete Mender is engineered for deep penetration and structural bonding. Its unique properties make it ideal for full‑depth crack injection:

  • Ultra‑low viscosity (≈8 cps)—flows like water
  • Surface tension ⅓ of water—wicks into microfractures
  • Structural polyurethane—strong but flexible
  • Fast gel time—begins curing in minutes
  • No pumps required—manual injection is enough

This combination creates a Microdoweling™ effect, where the polymer forms millions of molecular anchors inside the concrete, restoring structural integrity without brittleness.

How to Inject Concrete Mender for Full‑Depth Repairs

Below is the optimized, step‑by‑step workflow crews can follow in the field.

1. Drill Access Holes

  • Drill 3/8″ diameter holes, about 1 inch deep, along the crack.
  • Space holes based on crack length and depth.
  • Vacuum thoroughly to remove dust.
  • (Silica safety note: follow OSHA Table 1 compliance.)

2. Tape the Crack Surface

Use clear duct tape or Gorilla Clear Repair Tape to seal the crack surface. Avoid packing tape—it often fails to adhere to concrete.

3. Prepare the Cartridge

  • Install the Soft‑Tip™ Injection Mixer
  • Purge air according to Roadware instructions
  • Insert the tip into the first drilled hole

4. Inject Concrete Mender

  • Gently squeeze the gun to introduce material
  • Move between several holes to allow bottom‑up filling
  • Watch for:
    • Material traveling under the tape
    • Air bubbling from adjacent holes
  • Continue until the crack is filled to refusal

5. Finish the Repair

  • After ~10 minutes at 70°F (23°C), remove the tape
  • Shave, grind, or polish excess material
  • Blend the repair into the surrounding slab

Why This Method Outperforms Epoxy Injection

Faster Production

Crews can complete full‑depth repairs in minutes—not hours—allowing more linear feet of crack repair per shift.

Less Dust, Less Labor

The drill‑hole method is far less invasive than routing and chasing cracks, dramatically reducing silica dust exposure.

Stronger, More Durable Repairs

Concrete Mender moves with the slab, preventing brittle failures common with epoxy.

Lower Total Cost

No pumps, no ports, no specialized epoxy injection rigs. Just cartridges, mixers, and standard dispensing tools.

Ideal Applications

  • Warehouse floors
  • Distribution centers
  • Manufacturing plants
  • Retail slabs
  • Airport hangars
  • Parking decks
  • Cold storage facilities

Anywhere concrete cracks threaten structural integrity or operational efficiency, Concrete Mender provides a fast, reliable solution.

Concrete Floor Polishing & Repair: Why Roadware 10‑Minute Concrete Mender™ Is the Industry Standard

Large commercial buildings—big-box retailers, airports, warehouses, logistics centers, and convention halls—have made polished concrete floors one of the fastest‑growing flooring categories in the world. Facility managers and contractors now prefer polished concrete for its:

  • Clean, modern appearance
  • Low maintenance requirements
  • Dust‑free, smooth surface
  • High light reflectivity and energy efficiency
  • long-term durability under heavy traffic

Before any concrete floor can be polished, all cracks, spalls, joints, and surface defects must be repaired correctly.

Otherwise, poor repairs increase the risk of grinding failures, callbacks, and costly downtime.

This highlights why polished concrete floor repair is essential for reliability and uptime.

Why Pre‑Polish Concrete Repair Matters

Polishing equipment places extreme stress on the slab. If the repair material cannot bond, flex, and carry load, it will:

  • Pop out during grinding
  • Smear or melt under heat
  • Disbond under forklift traffic
  • Create visible defects that ruin the finish

This is why professional polishing contractors rely on high‑performance structural repair materials, not patching compounds.

⭐ Contractor Spotlight: C&C Construction Co.

“Concrete Mender™ eliminates the anxiety of repair failure.”

Curtis Venable, president of C&C Construction Co., has polished millions of square feet of concrete. His rule is simple:

“Cracks, spalls, and joints must be repaired correctly. Poor repairs undermine my credibility and cost everyone time and money.”

While Venable uses different materials depending on the job, he frequently chooses Roadware 10‑Minute Concrete Mender™ for its speed, strength, and reliability.

⭐ Why Contractors Choose Roadware 10‑Minute Concrete Mender™

1. Microdowling™ Technology = Permanent Structural Bond

Concrete Mender™ is an ultra‑low‑viscosity polymer that penetrates deep into micro‑fissures, creating a structural bond stronger than the original concrete. This Microdowling™ action allows repairs to:

  • Transfer load without cracking
  • Absorb shock from forklifts and heavy equipment
  • Resist chemicals and moisture
  • Perform in extreme temperatures, including freezers

“I know it won’t melt, smear, or come out when my polishing machines run over it,” Venable says. “Some of our repairs are 6–7 years old and still perfect.”

2. 10‑Minute Cure Time = Maximum Productivity

On large polishing projects, downtime is expensive. Concrete Mender™ cures in about 10 minutes, allowing crews to:

  • Repair
  • Grind
  • Polish
  • Keep machines moving

Venable recalls a 110,000‑square‑foot national grocery retailer project:

“With six people on polishing machines for three weeks, waiting for repairs to cure is not an option. Concrete Mender keeps the job moving.”

3. Repairs That Blend Seamlessly With Polished Concrete

Retailers demand clean, uniform floors—no mismatched patches or visible repairs. Concrete Mender™ blends naturally with surrounding concrete, producing a near‑perfect color match after polishing.

“A patchwork of colors is unacceptable today,” Venable explains. “Repairs must blend into a single, clean finish.”

  • Airport hangars
  • Freezers and cold storage
  • Industrial facilities
  • Polished concrete showrooms
  • High‑traffic commercial floors

It can be cut, ground, polished, and colored just like the surrounding concrete—without smearing or pulling out.

⭐ Summary: The Professional’s Choice for Polished Concrete Repair

Roadware 10‑Minute Concrete Mender™ delivers:

  • Permanent structural bonding through Microdowling™
  • 10‑minute cure time for maximum efficiency
  • Polishable, cuttable, grindable performance
  • Color‑blending repairs that disappear into the slab
  • long-term durability under heavy traffic

“Concrete polishing is more competitive than ever,” Venable says. “Concrete Mender helps me meet customer expectations for appearance, performance, and efficiency.”

Essential floor repairs for AGVs and warehouse robots

1 Comment

“If your AGV’s, robots, warehouse, floor repair could talk, they would ask for Concrete Mender,” said Richard King, Roadware, Inc.

Keep your robots moving. Keep your floors performing.

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.

Automated Guided Vehicles (AGVs) and warehouse robots are the backbone of modern distribution centers, AGV’s, robots, warehouse, floor repair considerations. 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

AGV’s, robots, warehouse, floor repair initiatives help give your operations a smoother path. 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.

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.
