Residents living near a Jersey City, New Jersey construction site were frightened as they watched “explosions” of smoke coming out of holes in the ground.
In order to break up some rock in the subgrade, contractors used a chemical called Da-Mite, according to NJ.com, which is a non-explosive rock splitting mortar. Holes are drilled into the rock, the chemical is then poured into the holes, and the mortar then expands with a force of around 18,000psi, causing the rock to break apart, according to the manufacturer’s website.
City spokesperson Jennifer Morrill told NJ.com that the chemical was not approved by the city’s Building Department. Jersey City Fire Chief also told them that he believes the explosions happened because they reacted with the air temperature “in a way it wasn’t supposed to.”
The explosions of smoke continued for around two hours and McGill said that some windows were cracked by flying rock.
A representative from the general contractor explained to NJ.com that the puffs of dust coming out of the holes is “completely normal” and does not agree that any windows were broken by the reaction. The site was shut down earlier in the day due to haphazard jackhammering that “failed to protect neighboring property,” according to Morrill.
On Daigh Company, Inc.’s website, the maker of Da-Mite, they include a note at the bottom of their “how to use” page, which states:
“Let Drilled Holes Cool Off before placing Dā-mite® in them. Cover the area with a tarp or other device after loading with Dā-mite® to minimize effect of blowouts. Also cover in case of rain to keep product dry until after Dā-mite®'s chemical reaction is complete.”

As you may already know, the NBA’s Milwaukee Bucks officially opened their new home, the Fiserv Forum, for the 2018-2019 NBA season last October. That new stadium is being heralded as the “World’s First Bird Friendly Arena,” due to many of the design features. Well, since the new one is open, we can only expect that the old, non-bird friendly (I’m assuming) arena has overstayed its welcome and has to go.
Let’s get 2019 started with the first building demolition by implosion of the year.
The Smithsonian channel is airing a series of shows titled America in Color, in which they enhance lost or forgotten video footage of the 1900s, beginning with the 1920s. Part of the first episode in the series shows the men that worked on skyscrapers in New York City and it’s been edited to show color, as opposed to black and white, for the first time.
Everyone has a camera in their pocket these days and when something goes down on the jobsite, you can bet it’s going to be captured on video one way or another. That can either be a great thing for marketing or an awful way to showcase your business.
Look, you could mobilize on site the boring old way by loading your heavy equipment on the bed of a trailer and driving it to site, or you could take a note from the Bravo Company of the 37th Engineer Battalion of the United States and spice things up a bit.
“World’s Largest” is definitely a sought after goal, especially in the construction industry. Sarens, a crane rental, heavy lifting, and engineered transport company in Belgium, has recently released a supersized crane that is being regarded as the largest crane in the world, by both size and lifting capacity.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
