The builder or his insurance had to replace the roofs. Costly, but fixable.

Crumbling concrete? That's a shit-show.

At least Massachusetts will fix this asap.

the state isnt bailing out homeowners. they’re bailing out concrete companies.

A friend of a friend was staying in a Bangkok hotel and took a look at the little balcony that belonged to his room. It was a fairly new hotel, and there was serious daylight between the exterior wall and the edge of the balcony that should have been part of the pour of that part of the building. It looked as if the exposed rebar was the only thing keeping the balcony from falling into the parking lot.

While there, he also saw another tall building being built, and the building to date was wrapped in concrete forms, some filled and some waiting to be filled, and scaffolding. Scaffolding made of bamboo and ropes. A storm had come through at some point and tore the scaffolding off the building, sending whatever workers there were plunging several stories to their deaths, When the storm had passed....new bamboo, new ropes, new workers. Apparently, Business As Usual in SE Asia.

Those workers were in the process of pouring concrete into forms to create the next storey. With water buckets of concrete hauled up by ropes.

Pyrrhotite is an iron sulfide mineral that can be found in concrete aggregates, such as sand, gravel, or stone, and can cause concrete to crack and crumble. When exposed to water and oxygen, pyrrhotite breaks down and expands, creating secondary minerals that can weaken concrete's structural integrity and lead to failure. This process can occur naturally after 15–20 years.
