QU'EST-CE QUE TU CHERCHES?
You used epoxy grout to fix a basement crack. It worked—for six months. Now, the leak is back, the client is furious, and you’re eating the cost of a redo.
Factor | Epoxy Grout | Polyurethane Grout |
---|---|---|
Cure Time | 4+ hours | 20-90 seconds |
Flexibility | Brittle (cracks under movement) | 300% elongation |
Water Resistance | Fails if damp | Bonds underwater |
Lifespan | 2-5 years | 10+ years |
A mall’s underground garage had leaks after every thaw cycle. Epoxy injections failed twice. After switching to polyurethane grout:
✔ All leaks sealed in one application
✔ No cracks reappeared after 4 years
✔ Saved $120K in repeat repairs
