Water flowing underneath can hollow out the land above. It’s a different kind of erosion.

I get the point of owning a house - basically NO ONE has the right to go into your house with your permission (unless it’s the police with a warrant or the case of real emergency, like a fire).

But with a condo, you have hand over your keys to the property manager, so they can enter ‘in an emergency. Pretty much the same for an apartment, except in an apartment, if the building is about to collapse or need major repairs (or if insurance, property taxes, or association fees skyrocket), you have the option to move out of an apartment without financial loss, rather than being stuck with a worthless condo that no one will buy, as now happening in Florida.

So what’s the big deal with condos? Low interest rates? LOL.

“up to several tens of centimeters” of settlement

---

Since this is happening in the U.S. wouldn’t ‘several inches’ be informative? And if one insists on using the oh-so-superior metric system, why not say ‘several decimeters’ of settlement?

IIRC, the bedrock in Miami is primarily limestone (Miami Oolite), a porous rock formed from reefs and marine sediments. And the limestone under the barrier islands is more porous than that of the mainland, increasing possible problems from groundwater flow, saltwater intrusion, etc., making it less stable for high-rise foundations.

Matthew 7:24-27

24 “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock.

26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”

Umm, not sure I'd want to live in a Miami condo.

On June 24, 2021, at approximately 1:22 a.m. EDT,[a] Champlain Towers South, a 12-story beachfront condominium in the Miami suburb of Surfside, Florida, United States, partially collapsed, causing the deaths of 98 people.

High-rises expect to see "up to several tens of centimeters" of settlement "during and immediately after construction," the University of Miami Rosenstiel School said

Ummmmm, we use inches in the United States - guess 'several tens of centimeters' sounds like a bigger number than 'a little under three inches'.

A house built on sand .....

[smokingfrog]

Are we sure it’s not caused by climate change? </sarc>

"The bedrock underlying much of Manhattan consists of three rock formations: Inwood marble, Fordham gneiss, and Manhattan schist, and is well suited for the foundations of Manhattan's skyscrapers."

So why are they building skyscrapers on sand in Florida?

[metmom]

Couldn’t see that one coming, could we?

The sinking "is primarily due to the gradual reconfiguration of the sand grains into a denser packing within sandy layers interbedded in the limestone" in the area, the study said. The researchers hypothesized a link between construction-related vibrations or groundwater flow and the sinking, according to the study. Other things like daily tidal flow and stormwater injection could also have factored into the phenomenon.

And...what about the size and weight of the buildings?

[bgill]

There it is. Florida is going to tip over from all the illegals and globull warming.

The foolish man built his house upon the sand. House upon the sand. House upon the sand.

The only Sunday school song I remember.

What are centimeters?
8 centimeters = 3.1496 inches

Are there no competent structural engineers any more?
