Would it be cheaper to print 3 houses with 2D printing and then rotate them into a single 3D house?

There was a house near my parents that they called "the Star Wars house". It was three intersecting concrete domes. There were no flat walls. When it went up for sale, the whole neighborhood went to the open house.

From the link in 4:

Built on a concrete slab foundation, the residence was constructed by spraying shotcrete onto steel rebar and wire mesh frames over inflated aeronautical balloons. . . . By the mid-1980s the house had fallen into disrepair, as water runoff from higher on the mountainside damaged the foundation, causing the walls to crack. After failed attempts at sealing the cracks, it was extensively restored in 1987.

Do you fix cracked shotcrete by shooting more shotcrete over it? If you had, say, a steep hill shellacked with a horrendously cracked and damaged shotcrete retaining wall in your backyard, with an embedded construction date of 1972 spelled out in little pebbles, are there repair options to stop the outflow of underlying soil through the cracks every time it rains? I know this question seems very specific, but really it's a more general concern about society and the built environment.

How high is society's retaining wall?

Because sprayed on concrete won't hold back any good amount of earth. You need something with deadman going back into the hill.

31, 33: Yes, you could dig out the crumbling shotcrete, verify that the reinforcing hasn't rusted away, replace the rusted parts, and shoot fresh concrete onto the existing and supplemented rebar.

As Moby suggests, installing tiebacks into the hillside is a good way to distribute the stresses and keep the forces in the shotcrete wall low. Similarly, installing counterforts can stiffen the shotcrete wall, and gives you a different way to install deep footings without undermining the existing wall.

A well installed shotcrete wall doesn't have to crumble; most swimming pools are shotcrete, and successfully retain water and resist soil heaving loads when emptied. You'll want a good contractor and may need a special inspector to make sure that they're set up correctly when they begin shooting.

Society's retaining wall is maybe 8 feet high? It starts behind a raised bed and goes up to rooftop level. I don't know how much actual retaining it's doing as it more or less follows the original slope of the hill, but dirt outflow through cracks when it rains is definitely a thing. How do you find out if there are dead men in the hill?


Posted by: lourdes kayak | Link to this comment | 08-29-24 11:20 AM

You have a wall behind your house as high as your house and dirt is coming through it. You need a professional to look at your wall.

35, 36: Moby is right; an 8' high retaining wall (that likely continues below the planter) should be professionally investigated.

Deadmen are cables that extend into the hillside, then get grouted in place. When the wall wants to flop back into your yard, the concrete at the end of the deadman is held by the dirt in the hillside and that steel cable holds the wall in place (straining under tension). At the backside of the wall [your yard side], there would be anchor points for the deadmen, though they might be concealed under a finish layer of concrete or stucco since they are not appealing. (They'd look like a grid of often circular splotches, if the hardware is embedded within the wall.)

Here's a simple image: https://foundation1.net/foundation-repair/dead-man-tie-backs/

If it follows the slope of the hill, that's probably reassuring. Unless the hill was steep.

39

The hill is rather steep, but the wall only covers the part of it directly behind the house, and the uncovered hillside has a similar slope and isn't eroding. No repair is possible without professionals for sure, but I don't think it's an actual emergency. I also don't think the shotcrete landscaping of 1972 is popular these days, so I bet the actual cost-effective fix would be to jackhammer out all the concrete and replace it with something more reasonable. That said, I'm kind of fond of the ridiculous wall, which has a bunch of interesting inset rocks and looks a little like a climbing wall: fun for 7-year-olds who don't mind skinned knees or narrowly avoiding rosebushes. I appreciate all the structural information, thank you!

In other news, our cracked garage door panel is an actual emergency, but still no word on the replacement estimate or timeline.

Apparently the middle school lights - literally all of them - started strobing today during last period and didn't stop. Ace and Pokey were rather freaked out. After a few minutes, the teachers were like, "I guess everyone put their heads down? You might not know if you have epilepsy? There's no protocol for this."

They just waited out the school day and were dismissed to strobe lights, and then I think they turned the power off to the school.

"...Let us no longer blind ourselves to the undeniable fact that the evil forces which have crushed and undermined and corrupted so many others are already within our own gates. Your government knows much about them and every day is ferreting them out. Their secret emissaries are active in our own and in neighboring countries. They seek to stir up suspicion and dissension, to cause internal strife. They try to turn capital against labor, and vice versa. They try to reawaken long slumbering racial and religious enmities which should have no place in this country. They are active in every group that promotes intolerance. They exploit for their own ends our own natural abhorrence of war. These trouble-breeders have but one purpose. It is to divide our people, to divide them into hostile groups and to destroy our unity and shatter our will to defend ourselves.

There are also American citizens, many of them in high places, who, unwittingly in most cases, are aiding and abetting the work of these agents. I do not charge these American citizens with being foreign agents. But I do charge them with doing exactly the kind of work that the dictators want done in the United States. These people not only believe that we can save our own skins by shutting our eyes to the fate of other nations. Some of them go much further than that. They say that we can and should become the friends and even the partners of the Axis powers. Some of them even suggest that we should imitate the methods of the dictatorships. But Americans never can and never will do that..."

I took a tour of two Frank Lloyd Wright houses over in Manchester today. One of the houses was of the "Usonian Automatic" style. "Automatic" because it was made of cement blocks that an owner was supposed to cast and assemble themselves. Of course the system was all too complicated and it never worked out like that. Of the seven examples built, arguably one was assembled by an owner. Also, it had a flat roof, which is a really stupid idea for New England, so a fair amount of water damage.

having now read the article on the bewilderingly large cob house --

To meet stringent regulations, walls were insulated with polystyrene - 100% recyclable and A+ rated for sustainability - and rendered with lime.

Squinty eye suspicion. Is it recyclable when you haven't scraped all the cob off? And how does a polystyrene layer affect the humidity management of cob?

Aesthetically, it just kills me how badly the modern windows interrupt the curving cob walls. Either use little castle-like windowslits, or stick bottles in like a proper hippie, or get curved glass. There's a hardware store in SF that sells window squeegees in a set of curvatures to match the proper bay and turret windows with curved glass.

This is one of those embarrassing things that I probably shouldn't admit outloud or online, but until recently I thought Moby was talking about building houses out of corn cobs. I see now that cob is basically adobe? My understanding is that adobe cures slowly in warm, arid conditions, which makes it a useful building material in the southwestern United States, but how does it work in other parts of the world? How do mudbrick houses not fall apart in the northeast, where the soil is damp for much of the year?

Cob works partly from "hat and boots" (don't put the cob part in standing water) and largely because you use the clay fraction of the soil. Once that's pounded solid and dried, it takes quite a lot to soften it again.

AIUI, if you discover someplace you let it erode a bit, you (forcefully) slap some more cob on it. And fix the eaves.

82: we've been doing that joke a fair bit.

83: oh, you bet. The vaguely colonial feel to the project adds to it. I am wondering what adventures the thing will encounter - obviously it will be packed in a shipping container, trucked to, say, Marseille or Le Havre, craned by efficient robots and even more efficient operatives onto a huge ship, and then offloaded in much the same way in Abidjan. But what happens after that? A gaily decorated truck crammed with coffee sacks and cheerful passengers? A monster Berliet roadtrain out of the fifties? As I understand it even a boringly normal approach would see it getting a trip on the Chemin de fer Abidjan-Niger, which surely rumbles through the forests and the savannahs putting wild beasts to flight even if it uses some pretty modern looking diesel electric locos. Can we get it precariously balanced on a traditional water craft up one of the rivers, perhaps towed by a paddle steamer? The geography doesn't admit of it being hauled over the mountains by main force and unnecessary suffering but an airlift in a giant ex-Soviet helicopter manned by sinister mercenary aircrew can't be ruled out.

The Buddha may not have mentioned Porsche by name, but only because his acolytes wouldn't have understood.

I thought you were supposed become less attached to the material world as you get promoted.

Also, I look forward to 3D printed ice palaces.

No, it's like Menshevik Marxism. You have to max out each level before you can progress to the next.

I don't really understand Marxism either.

That's the cue to cross this with the BSW thread, but I'm not sober enough right now.

Not so much an architectural style as hanging a lampshade on their inability to print flat walls or tight corners.

I walked by a crew pouring a foundation using forms and a hose the other day. I'm going to guess these guys have a background in 3d printing and not construction.

It's supposed to be stronger than a foundation made of block.

I don't have a background in construction or 3d printing. I also didn't rtfa. I'm just annoyed that what if printer but big is an idea that gets funding.

The house-sized dot matrix printer failed, because the edges with the little spoke-holes in the houses made a mess when you pulled them off.

Just going to refer to as many processes as I can as "printing". Using massive rollers to extrude steel girders? 3-D offset printing. 100 ton industrial press for car parts? 3-D movable-type printing.

Drop-forging mighty billets of steel using a colossal steam-powered trip hammer, or, as I call it, "a 3-D typewriter".

Samsung Heavy Industry's Busan shipyard assembled over sixty thousand tonnes of steel into the MV Maersk Normandia in a process nicknamed "3D bookbinding". On 4 August 2012, senior Maersk and Samsung executives watched as the construction dock was flooded and the fully bound and proofread container ship was 3D published.

On 15 December 2019, after an engine failure in the Strait of Malacca, the Maersk Normandia drifted on to a submerged reef and suffered severe 3D editing below the waterline.

Four years later, on 2 January 2024, the vessel was mildly 3D criticised by Houthi rebels in Yemen, using an Iranian-supplied anti-ship ballistic missile.
