Yeah, you could see the whole Reflecting Pool as a colossal failure, but OTOH, it gives chemists and materials engineers a chance to geek out in public about all that they know about the chemistry of polyurea laminates and "bond-breaking edge stress". So overall, I'm choosing to be happy for them.
Mechanism and updated prediction for the epic fail of Lincoln Memorial Bioreactor's polyurea coating! First chemistry, then physics It was sprayed in big sections. In addition to pool edges, failure will concentrate at the OVERLAP SEAMS between sections because they likely barely bonded at all. 1/x
