    The problem with this kind of innovation is that it’s improving what’s already one of the fastest and easiest parts of building a house. Digging foundations, plastering the walls, doing the plumbing, doing the electrics and laying the flooring can all individually take longer than the bricklaying, and are much harder to automate.

        Guessing you didnt read it, because its in danish.
        The article specifically mentions that this technique uses 30% of the material that would have been used for precast.

          But what does that mean for strength? I also see surprisingly little “armouring”. Not sure how that’s called in English - the metal wires in-between.

            I’m not sure about this company but there’s one in the US that has an embedded nozzle laying down steel cabling inside each concrete bead.

            I’m just guessing, but it is probably reinforced with fiberglass or a similar fibers in the cement.

      One of the things that this project is testing is how the foundations are made. They do not have to clear the trees to dig and level out the area to fill in loads of gravel just to make a concrete pour. They are somehow able to make the foundations around existing structures like trees and on somewhat uneven ground.

        This machine looks much bigger than a wheelbarrow, and you still need to dig the foundation, so I don’t see how it could possibly need less space to be cleared than just pouring concrete into a hole would.

          It runs on tracks, so it might be slimmer on the ground level than the conventional construction vehicles. Sure a wheelbarrow is smaller, but I don’t think that’s a realistic option, lol.

            When I’ve seen foundations for homes get poured and they haven’t been on a large construction site that’s already been flattened (where the ability to work around things like trees wouldn’t matter), it’s been done by having one or two builders fill up a wheelbarrow with concrete where the concrete mixer lorry could drive to, then wheel it to where the foundations were being poured and empty their wheelbarrows into the foundations.

      That is why developers over here love to sell houses that are just walls, windows, roof and facade. You get to juggle 10 different contractors until finished yourself
