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.
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.
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.
