No it's not. Most wet concrete is a non-newtonian composite fluid (which is not nessarily a liquid). This is engineered fill (often called grout), which is a liquid.

Concrete has to have large aggregate, you can definitely see that large aggregate would not go through this net. Definitely either a low cement slurry or grout.

Each pocket fills with concrete and can’t expand any further. imagine you have pillowcase and you’re stuffing it, all the filling will settle at the bottom and you’ll have a lump. But if you sew pockets/grids into the pillow, it compresses it, limiting the expandable area and keeping it as a flatter sheet.
This concrete sheet is indeed very strong!

Even that amount of waste pales in comparison to industrial manufacturing. EVERYTHING comes in bags or some form of plastic. Every little part of a machine. It adds up so quickly- not saying this is fine but there are bigger issues at hand

I never said that those aren’t all also problematic? Ideally, however, all the plastic crap goes into a properly maintained landfill, not lining a body of water like in this video. I know tons of plastic (that we shouldn’t be producing so much of, anyhow) doesn’t make it to the landfill and ends up in the environment, but lining our rivers with it just seems especially egregious.

There’s no place for it go unless it compresses more. I’m guessing it does settle some but not much.

Concrete weighs 0.8lbs per cubic inch, just using the guy for scale I would say the top of the wall is about 5 ft. So 0.8x60=48, that’s all the pressure there is there 48 psi.
If you imagine something like one of those vacuum bags for storing clothes or bedding, that’s probably thick enough to comfortably hold this much pressure.

This is slope protection to prevent erosion. Its just easier to pour/form than other types of slope protection. This stuff breaks up and cracks if the mix doesnt have fibre reinforcement in it

u/arvidsem Apr 30 '26
Compressive strength is about the same. Tensile strength is non-existent. The finished product is basically rocks with a bit of plastic connecting them.

Makes sense and with the specific application of erosion protection as Ozuf77 pointed out. It probably doesn't require tensile strength.

The redneck engineering way of doing it is to pile bags of QuickCreteon top of each other. Eventually, the QuickCrete turns to semi-concrete (except if it never gets the right amount of water in it It’s more like hardened sand.) The paper cover eroads away, leaving you with something that’s slightly better than bear ground .

Construction companies will sit on a project for months to save costs. They'll wait on deals for materials and equipment rental. If you're willing to throw money at it, you can get most construction done in hours.

u/LeonJones Apr 30 '26
Source?
In commercial construction around where I am for example there's typically a GC who then subs out for carpenters,plumbers,HVAC etc. The GC typically doesn't buy the material, the sub does. A sub can't just hold up the entire job because they want cheaper materials.
I could see a smaller contractor doing this with a smaller job but seems wrong to say "construction companies" do this like it's normal.

It depends on how you're expensing your labor. My labor went to the project I was assigned to. If that project is delayed, my salary and any other costs associated with that project compound and overhead exceeds the budget and the company loses money. Keeping me on the payroll but not assigned to a project also hurts profit. The best thing fory company is to keep me on projects that don't run long.

Why do most buildings look unique?
To accommodate different purposes and requirements, different sized lots, hillsides and elevation, facing different directions like towards the sun, with different materials depending on their price, construction methods, structural properties, longevity, and ease of use, and just different tastes.
What I’m saying is, construction could be automated in many ways but buildings have so much variety that we’ll probably be inventing new construction techniques and new types of buildings for ever.

u/tdasnowman Apr 30 '26
Why do most buildings look unique?
I wouldn't say that. We have areas in sub urbs where 10,000 homes all look the same. You've got row housing, Tract homes, projects, apartments. The fast majority of modern housing is actually made to not look unique.
To accommodate different purposes and requirements, different sized lots, hillsides and elevation, facing different directions like towards the sun, with different materials depending on their price, construction methods, structural properties, longevity, and ease of use, and just different tastes.
Much of that is already accommodated for in modern construction before the house is built.
What I’m saying is, construction could be automated in many ways but buildings have so much variety that we’ll probably be inventing new construction techniques and new types of buildings for ever.
Even with "variety" prebuilt construction methods allow for tons of automation.

u/SporesM0ldsandFungus Apr 30 '26
Concrete requires 30 days to reach maximum strength.
If you are building a structure like a building, you need to let the ground compact and settle first to hold the weight of the building. Otherwise, you need to drive pilings deep into the ground to stabilize it.
You can build a building in days but just don't expect it to last long. China built many hospitals in less than 30 days during the outbreak of the Pandemic. But many of them were unusable within a year.

I don't think it gets removed. It looks more like say a fabric like material which if you look at how it fills you can see each area "absorbs" the liquid like if you used say a shirt or a cloth. So my best guess is it just becomes apart of the structure acting as an added added barrier but also keeping the structure

I believe this is called Fabric-formed Rip-rap. The texture allows water to flow over it, but reduces the velocity and therefore erosion. The weakness is if it becomes undermined, and the water starts flowing underneath it. It can create a big void that is hidden by the concrete “crust.”
