Question about bracing forms for slab


We are having a concrete slab poured next to the back of our house and existing porch & sidewalk, and to save money we are digging out excess soil and building the forms. This will require digging out about 4" of sandy soil, plus footers around the edges that will support walls & roof, and placing forms on 2 sides of the slab. Since the top of this slab will be at grade level, surrounded by soil on those 2 sides, is it necessary to dig out more soil and use kickers to support the forms, or can we just use stakes and then pack plenty of dirt on the outside of the forms? Also, do we need to use 2x4s or will 1x4s do? The size of the slab is about 10.5 x 14 feet.

Thanks for your help

You shouldn't need kickers unless the form is really tall. Metal stakes would work just fine.

2x4s would bow less between the stakes, so go with those.

I don't recall seeing metal stakes in our little hardware store, just the wooden ones. If that is all we have, will they do if we put them really close together? How many inches apart would you recommend?

Metal really would work best. As for how far apart, I'd have to defer to one of the guys on here that's on the other end of the chute.

we usually stake w/#4 bar then set forms at whatever grade,,, we have form pins but don't always use 'em,,, buy some 4' lengths of #4 rebar & cut 'em in 1/2,,, bit more expensive to buy 2' lengths but you wouldn't have to cut them OR grab 1x stakes & just use more of 'em there's not a big amount of lateral pressure from a 4" slab

Thanks, Mort ... I will check with the hardware store tomorrow to see if they carry metal stakes.

itsreallyconc, are you saying you use short pieces of rebar for stakes? We have a lot of 4' rebar on hand that we used for another project.

yes & i said it 1st we;ve also been known to use big rocks, 5gal bkts fill'd w/stone, & chunks of conc from old slabs you can cut your leftovers into suitable size for stakes,,, i don't like cutting long ropes but necessity is often the mother of invention
