At the ground level of the complex, vehicles can drive in next to a pool deck where residents would lounge in the sun. Mr. Morabito in 2018 said that the waterproofing below the pool deck and entrance drive was failing, “causing major structural damage to the concrete structural slab below these areas.”

The report added that “failure to replace the waterproofing in the near future will cause the extent of the concrete deterioration to expand exponentially.” The problem, he said, was that the waterproofing was laid on a concrete slab that was flat, not sloped in a way that would allow water to run off, an issue he called a “major error” in the original design. The replacement would be “extremely expensive,” he warned, and cause a major disturbance to residents.

In the parking garage, which largely sits at the bottom level of the building, part of it under the pool deck, Mr. Morabito said that there were signs of distress and fatigue.

“Abundant cracking and spalling of varying degrees was observed in the concrete columns, beams, and walls,” Mr. Morabito wrote. He included photos of cracks in the columns of the parking garage as well as concrete crumbling — a process engineers refer to as “spalling” — that exposed steel reinforcements on the garage deck.


Mr. Morabito noted that previous attempts to patch the concrete with epoxy were failing, resulting in more cracking and spalling. In one such spot, he said, “new cracks were radiating from the originally repaired cracks.”

The report also identified a host of other problems: Residents were complaining of water coming through their windows and balcony doors, and the concrete on many balconies also was deteriorating.

I saw that false claim by Charlie Kirk yesterday. Didn't repost it because he's not all that influential, don't ya think?

No, but Tucker and gang may jump on it. Geez.

SURFSIDE, Fla. (CBS12) — The Mayor of Miami-Dade County ordered an audit of all buildings in the county at the 40-year point and beyond in the wake of the collapse of 12-story building in Surfside.

On Saturday, Mayor Daniella Levine Cava also said county leaders did not know of a 2018 report which found major structural damage in the condo.

The death toll remains at four, with 159 people unaccounted for. Authorities said another 127 people have been accounted for in the collapse.

Crews, working around the clock, did not recover any victims overnight.

On Saturday, Mayor Cava said the search for survivors is being hampered by smoke from a deep fire that's been burning for some time.

Cava says it's hard to locate the source, and crews are using all tools from foam, water, and infrared to locate the source and minimize the spread of smoke.

Crews also dug a trench in an effort to isolate the fire.

"The world is watching and we thank everyone," said Cava.

The reports of spalling suggests that the rebar was corroding.

I bet they used a poor quality aggregate in the concrete.

Rebar corrosion is commonplace unless they coat it. It's a common problem here in the Midwest when they use rebar of bridges and the road salt works its way into the concrete. I bet it's a combination on ingredients: concrete, engineering, building it on an unstable footing.

Nearly 6,000 homes in Donegal, Mayo affected by concrete issues - report
Updated / Tuesday, 13 Jun 2017 23:18
Report of the Expert Panel on Concrete Blocks found the problems were largely confined to specific areas in both Doengal and Mayo

An expert report for the Government has found that up to 5,700 homes in Donegal and north Mayo have been affected by problems in their concrete blockwork causing buildings to disintegrate and external plastering and rendering to crack.

The dwellings are single storey, dormer and two-storey with both housing estates and one-off rural houses affected.

The report of the Expert Panel on Concrete Blocks found the problems were largely confined to specific regions in both counties.

In Donegal the homes affected are mainly located in the Inishowen and Letterkenny Municipal districts, where the problem is caused by a mineral called muscovite mica in concrete blocks.

In Co Mayo, the problem is caused by pyrite in the concrete blocks and the houses affected are largely concentrated in the northern parts of Ballina and the West Mayo Municipal districts.

According to the report 28 housing estates in Donegal have been affected.

In addition Donegal County Council found that 60% of social houses built in Inishowen between 2000 and 2008, and 23% built in Letterkenny, are suffering structural distress and cracking.

On the basis of these findings the Expert Group said the minimum number of private houses affected in Donegal was 1,200 but that total could be as high as 4,800 homes in the county.

In Co Mayo, seven housing estates with 315 dwellings have been identified with pyrite in their blockwork. Another 30 one-off houses in the county have been similarly affected.

In addition a total of 17 social housing units across three council estates are also affected according to Mayo County Council.

The Minister of State for Housing and Urban Renewal Damien English said he hoped that the publication of the report will assist affected homeowners in finding and acceptable solution and remediation measures for their impacted dwellings.

However, remediation options highlighted in the report involve the demolition of buildings in some cases and the demolition and rebuilding of external walls in others.

Welcoming the publication of the report today, Minister Joe McHugh said it is important now that a Redress Scheme is put in place for all homeowners in Co Donegal who have suffered as a result of all the deficiencies in our planning and building regulation systems between 2000 and 2006.

He said: "It is clear in the report, that those who bought homes or who build their own homes in this period of time did so without any knowledge whatsoever of the problems ahead and in those circumstances they should have access to a redress scheme"

I wrote about this the day it happened. Could be contaminants fro cement kilns that burned haz wastes as a business in 70s and 80s

From a quick look online It seems Salt AIR corrosion is much more a worry than underground Salt.
