Surely there must be a better way of laying a slab floor than pouring a half foot of concrete across the entire structure.Seriously wondering why you don't just lay a perimeter footing for the wall, and pour individual squares room by room, and use the leveling compound to bridge the squares. The joins will all be under the drywall anyway so why would you even care?
>>2879955Perimeter foundations are a thing.
Concrete for large pours is mixed off-site by a team of people and brought with a truck, which is driven by a person. All of this is more or less the same regardless of the amount of concrete needed. It's most cost-effective to do concrete in as large a pour as possible.However, if you're doing it yourself, then YOUR time is most precious. The downsides I see as far as batched, purpose-pouring, is that it may conflict with certain building codes, and may end up being less structurally sound overall since the individual components didn't solidify out of a single cast.
>>2879955This is reasonable if you’re doing it yourself.>>2879963You’d want to leave some of the rebar exposed on each… um… lift? section?… to tie into the next one.if you look at tall buildings you can see the exposed rebar in the columns to tie into the next lift.
The issue is really the cost balance of materials. The pain is really in structural timber, but that's had a flow on to cement slabs people are using to replace timber floors. Even chip board flooring is expensive. And you could just throw your hands up and say that everything is expensive but I've got people living in cars, tents, squalid bunk houses.I can't give up because they can't give up.
>>2879963they build 90 level skyscrapers out of multiple pour slabs, it's fine as long as the rebar is tied between sections and the slab edge is prepared properly.
>>2879962this modern method of putting wood on a metal stick is gay as hell
>>2880036What are some examples of proper edge preparation?
>>2880052basically just leave a rough edge for better surface area/adhesion and pour the second part before the first has completely cured, plus vibrating to work the new concrete into all the cracks. otherwise you may end up with a 'cold joint' which is a weak mating. it's more of a problem in hot weather since the first pour might cure before you can do the second part, they use additives to slow down curing in that case.
>>2880092Do you have any pic examples of this?
