Ardex products used to help rebuild the Pentagon
The original plans for the project included tearing up the entire floor where the airplane severely burned and dented the concrete. Ardex recommended the restorers use K-15 instead, to fill in gouges, cracks and uneven surfaces.
Ardex's Feather Finish is also being used in the restorative efforts. Feather Finish is a cement-based finishing underlayment.
