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
But before any concrete floor can be polished, every crack, spall, joint failure, and surface defect must be repaired correctly. Poor repairs lead to failures during grinding, callbacks, and costly downtime.
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.
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.”
Retail stores and big‑box chains
Warehouses and distribution centers
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.”

“If your AVG could talk, it would ask for Concrete Mender. ” Richard King, Roadware, Inc.
Keep your robots moving. Keep your floors performing.
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. 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
Your AGVs get a smoother path. Your 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.
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.
Joint curling is caused by moisture‑related slab deformation. Roadware 10 Minute Concrete Mender™, installed using the Applied Adhesives GMP 050 pump, stabilizes curled joints by penetrating deep into the concrete, restoring aggregate interlock, and making the slab effectively jointless. This method provides a permanent structural repair, eliminates vertical displacement, and is traffic‑ready in minutes.
Remove loose material and create a shelf on both sides of the joint with a minimum profile of 1.5” deep and 2” wide on each side. Vacuum and thoroughly remove dust and contaminates.
Create a repair base by filling repair area halfway to grade with bulk mixed 10 Minute Concrete Mender™ combined with 10-20 grit silica sand.
Use a ratio of 1 Part mixed Concrete Mender to 2 parts silica sand. Up to 1/2 part additional sand may be added during application to assist with troweling and placement. Be sure to leave the lower half surface rough and sand covered to accept the next layer.
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
Bridge maintenance crews in West Virginia are using Roadware 10 Minute Concrete Mender to repair hairline cracks in bridge decks. Concrete Mender is a high-performance, rapid-curing concrete repair product designed to restore structural integrity and prevent further deterioration. It is specially formulated to bond well with existing concrete and withstand harsh environmental conditions. Applied with 600 ml dual cartridges and a needle tip mixer, Concrete Mender allows for precise application and minimal waste. The product’s quick curing time of just 10 minutes facilitates rapid reopening of traffic.
Before application, cracks are lightly scored with a diamond blade to ensure proper bonding. Dust and dirt are removed to achieve a clean surface. Concrete Mender is then applied to the top of the crack and allowed to soak in, creating a strong, durable seal. Silica sand is sprinkled onto the wetted surface to enhance bonding strength and surface texture. The material is allowed to cure for 10 minutes, after which traffic can resume immediately, reducing downtime and maintaining safety.

Using Roadware matchCrete Clear, cement powder, and rock to make exposed aggregate concrete spall repairs.
This driveway was seriously damaged from deicing snowmelt treatments. I simply routed out the perimeter of each of the damaged areas. I then thoroughly power washed to remove all dirt and loose debris and allowed the area to dry. I mixed up four separate batches of Matchcrete mender with 1/4”pea gravel seeded on top. I then applied a small amount of fine sand before the surface had hardened. The homeowner was extremely pleased with the finished results!! Thanks so much to the folks at Roadware Inc for their insight and positive support on this project!! Please note, I will diamond cut, and route open the original joints after full cure time.

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.
