I am interested in building large boulders 6-8 feet tall. I have seen other concrete craftsman create them with polystyrene and a GFRC mix. Instead of using the metal lath. I have even seen that the company Strata is using their S.A.B.S method with polystyrene and GFRC mix to build entire houses. I sure would like to see, and I think many other people would like to see you create a video using a strong structural GFRC mix on a Polystyrene base.
So, odd question. I have a number of odd-sized pieces of styrofoam from different purchases, none of them small, but also not big enough for something like this, or for a project I've been working on. I've been seeing videos of people making various things with expanding insulation foam, including giant pumpkins that were then covered with mortar to make them durable outdoors. For my project it would require a bit more cans of the stuff than I really have the budget for. So my question is: Could I use that expanding foam to sort of glue my random pieces together and fill in gaps between the odd-shaped pieces? I mean, I'm sure that I could... but would it be strong enough to use in the manner you are using it for this bench? For reference, my project is a sort of container garden, using two filing cabinets and a wood shipping box as a three-tiered center block. I also wanted to use the drawers from both filing cabinets to make a sort of cascading surround on either side, with the three finished pieces covered so that the whole thing looks like it was carved out of stone. Or at least looks somewhat more organic. The styrofoam would be part of the side supports, so would not be carrying anything super heavy (disguised flower pots in the drawers) over any given surface point.
18.35 Thank you for the videos you post. I make marbled concrete slabs, and I have a problem that when a slab dried it becomes culrled and hairline cracks appear on the face. Do you have solutions for these 2 problems? Thanks
about aluminum also being a possibility there....as your attorney I would have to discourage its use on concrete... as an alternative to steel it might seem like a sound choice, but there are some chemical interactions to consider here. You see, aluminum and concrete can have a tricky relationship due to the alkalinity of the former, namely due to the presence of calcium hydroxide and other alkaline compounds that are byproducts of the hydration process... this high pH environment can cause corrosion and oxidation issues with aluminum. Over time, it tends to react and form aluminum oxide, which expands and can lead to cracking and deterioration of the concrete (much like it happens with steel when water gets to it) which counterproductively will cause the aluminum to weaken-and the concrete to lose its integrity. Much like some instances you refer in some of your videos (I want to say that that of the table top is one of them) that steel can indeed in some occasions be detrimental, the thing is that aluminium will almost certainly be so. Because with our friend the steel you know you don't have these same chemical worries. Steel gets along just fine with the alkaline nature of concrete. And as you also referred, it's cheaper and abundant-so much so that it is the classic choice for a reason: simple, strong, and chemically compatible with concrete-the tried and true companion to lean on (figuratively as literally)....perhaps when you were young and while you were trying to stand up straight at pubs when it was time to leave... Good ol' steel!... Oh, the name of the joint? Re..Bar ha! 😬😅
Pushing the long nails into the styrofoam in pairs - and angling them slightly in opposite directions - helps prevent them from pulling back out.

Did I just spot a bottle on the shelf that is labelled "Unicorn Farts"? Otherwise great video!
Sure, what do you label your bottle of unicorn farts?
