Dive Brief:
- Concrete Innovations owner Charlie Griffasi and his workers were puzzled when they found foam in the lobby floor of a project they were working on during only the second step of a six-step process.
- The concrete-polishing company from Buffalo, New York, was working to finish a retail-store lobby when a Drivit wall insulation was being put up at the same time that the concrete was being put down.
- When the workers moved into the store itself and applied an acid stain the owner had specified, they found the next day that there were stains in the stain because something foreign had been spilled onto the concrete.
Dive Insight:
The problems, which the company was able to solve by changing the grit progression in the lobby and regrinding the store and restaining with a different color scheme, could have been avoided with better scheduling during construction and more care by whoever spilled. Flying foam specks and wet concrete are a bad mix.
