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.

Ultimate Guide to Fast-Curing Concrete Repairs for Warehouses

Leave a comment

Why Fast-Curing Repairs Matter in Modern Warehouses

Warehouse operations are faster, heavier, and more continuous than ever. A single cracked slab or spalled joint can disrupt workflow, damage equipment, and create safety hazards. Traditional concrete repair products often fall short because they cure slowly or fail under dynamic loads.

Key challenges facility managers face:

  • Heavy forklift and truck traffic
  • Tight logistics schedules
  • Rising maintenance costs
  • Pressure to reduce downtime
  • Need for long-term structural durability

This is why fast-curing, structural-grade materials are now essential—not optional.

Roadware 10 Minute Concrete Mender is widely recognized as one of the most reliable heavy-duty floor repair systems for industrial environments. Its unique Microdoweling™ action allows the material to penetrate deep into the concrete matrix, creating a permanent structural bond.

What Makes Concrete Mender Different?

  • Ultra-low viscosity (8 cps) for deep penetration
  • Structural bonding that restores aggregate interlock
  • Fast cure times—traffic-ready in 10–15 minutes
  • High durability under forklift and truck traffic
  • Works in extreme temperatures (down to –20°F)
  • Minimal surface prep reduces labor and downtime

This is true structural concrete repair designed for demanding industrial environments.

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.

Your AGVs Will Thank You

As Roadware’s Richard King says:

“If your AGV could talk, it would ask for Concrete Mender.”

Because smoother floors mean fewer breakdowns, less wheel wear, and more uptime.

EXAMPLE

1 Qt side A,

1 Qt Side B,

4 Qts 10-20 silica sand,

Up to 1 quart additional sand as needed.

Once the first layer sets and turns grey, continue with an additional layer up to flush with the surface.

The mixed material should always be resin rich and the sand should be fully saturated when applying to the repair area.

For extra surface strength, 30 grit aluminum oxide may be broadcast and troweled in place on top as the materials start to gel in about 5 minutes after placement. Allow to fully cure and grind flush within 24 hours. OPTIONAL: Re-saw the contraction join

New Freezer Floor Coating Stops Concrete Dusting

3 Comments

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.
