Earthquake Sustainability


The 2018 Anchorage, Alaska Earthquake
On November 30, 2018 at 10:44 PM, a 7.0 earthquake hit Anchorage, Alaska. The IHG Staybridge Hotel pictured above was under construction. CastleRock-InsulStone had been installed between November and April because it could be installed in below zero temperatures, insulated & mortar-less. The building and exterior suffered considerable damage with broken studs and buckled sheetrock and stucco, but InsulStone survived with minimal damage. See the reference from Alaska Construction Management Services who oversaw the project.

"Shortly before the closing of this project, a large and destructive earthquake hit the Anchorage area resulting in significant damage to the finishes on the hotel. Despite the potential for severe damage to the exterior stone cladding, in the end we only had to replace 4 stones that fell off the building. This is a tribute to the design of the InsulStone panels, which are both durable and attractive". (Alaska Construction Management Services)
