Quick Summary
Roadware 10 Minute Concrete Mender is ideal for structural repair, rebuilding spalled joints, restoring load transfer, and eliminating forklift impact.
Metzger McGuire (MMG) polyureas are ideal for joint protection in new slabs that are still moving or shrinking.
1. Product Purpose: Repair vs. Protection
Roadware 10 Minute Concrete Mender — Structural Repair
Roadware is engineered to penetrate deep into concrete and bond at the aggregate level. This creates a structural, monolithic repair that restores slab integrity.
- Rebuilds spalled contraction joints.
- Restores aggregate interlock
- Eliminates “thunk‑thunk” forklift impacts
- Ideal for older slabs (12+ months)
Metzger McGuire — Joint Protection
MMG polyureas are designed to protect contraction joints in new slabs. They absorb impact and support wheels crossing the joint.
- Best for new slabs still shrinking
- Protects joints from early damage
- Flexible enough to accommodate movement
2. Chemistry & Performance Differences
Roadware 10 Minute Concrete Mender
- Ultra‑low viscosity polyurethane
- Deep penetration and aggregate bonding
- Structural repair, not just filler
- Traffic‑ready in 10 minutes
- Sand‑loadable for full‑depth rebuilds
Metzger McGuire Polyureas
- Medium‑viscosity polyurea
- Designed to fill joints, not penetrate
- Flexible for slab movement
- 1–2 hour return to service

3. Best Use Cases
| Scenario | Roadware | MMG |
|---|---|---|
| Spalled contraction joints | Best choice — rebuilds edges | Not ideal — filler fails again |
| New slab joint filling | Not recommended | Best choice — protects joints |
| Crack repair | Excellent — structural bonding | Not designed for cracks |
| Heavy forklift traffic | Eliminates joint movement | Reduces impact only |
| Full‑depth joint rebuild | Ideal with sand loading | Not designed for rebuilding |
4. Cost Comparison
Material Cost
Roadware costs more per gallon, but yields twice as much with added sand and has a lower lifetime cost because it’s more durable.
Labor Cost
Roadware installs faster with minimal downtime.
Lifetime Cost
Roadware typically wins — structural repairs do not need to be redone.
5. Final Recommendation
If your slab is older than 12 months or showing signs of spalling, Roadware 10 Minute Concrete Mender is the superior long‑term solution.
If your slab is new and still moving, Metzger McGuire polyureas are the correct choice.
