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.”

Hello,
We are currently evaluating Roadware 10 Minute Concrete Mender to fill voids between a SuperHard topping layer and the underlying concrete substrate.
Our process is to locate the voided areas by sounding, drill 3/8-inch holes along existing cracks, and inject the Concrete Mender through those holes. During application, however, the two components are not dispensing at an equal rate. Approximately half of one side of the cartridge is being used while only about 25% of the other side is advancing.
As a result, the material is not mixing at the proper ratio and does not harden after injection.
We would appreciate your assistance in determining what may be causing the imbalance. Specifically, we would like to know whether this could be related to the dispensing gun, cartridge pistons, flow restrictor, static mixer, backpressure during injection, or our application method.
Could you also confirm the following for this type of delamination repair:
The correct dispensing gun and cartridge configuration
The recommended static mixer and injection tip
Whether the cartridge should be purged before installing the mixer
Any maximum recommended injection pressure or resistance
Whether vent holes are required to allow displaced air or excess material to escape
Any temperature or storage conditions that could cause uneven flow between the components
This application has the potential to require a substantial volume of material. If we can establish a reliable and repeatable process, we anticipate purchasing a significant number of cases for continued use.
We can provide photographs, cartridge lot numbers, gun information, and additional details about the application if needed.
