of course you can,,, after all, its your house :wink2: how big an area ?
whether or not its a good idea depends on this: your geographic location. conc is a liquid that turns into a solid,,, when curing, it shrinks a bit as the water & cement complete their chemical reaction,,, once hard, it reacts to temp as does any other solid,,, it expands when heat is applied & shrinks as the heat is removed. where's YOUR where ?
expansion joint ( asphalt impregnated homosote ) is commonly installed when placing conc against a structure - you wall,,, you can also use foam sill seal, snipe hair, chicken feathers, or any other compressible provide space for the conc to expand w/o damaging your wall ( In this case, permanent form )
forms are commonly wood, steel, foam, or dirt - nothing says you can't use existing wall of stone - just use your head
thanks for checking :vs_wave: hth,,, even tho this is all you'll need to know, others will get up in a bit & post their $ 0.22 or $ .03 anyway,,, after you read all of them, remember that conc highways do not use expansion jnt material
