Fill In Sunken Living Room With Cement Or Wood Framing?


yes i know how to with each
i know if it do wood , id have to adheise and screw all down for no squeaks,
i know if i use cement , i need to fill it in a bit , then use road mesh , and tie into existing

just not sure all the pro` and cons

its a nice home , with a real nice engineered flooring throughout , even inside this sunken area ( 14 ft x 15 ft, by 7 inches deep)

cement , i know is stronger,
but would be so much more labor intensive , and messier.and i`d have to make sure its perfectly level , and even, with the existing upper floor, so i can fill in with that engineered flooring .

wood seems to be faster easier , and neater ,
i don`t want it to sound hollow when we are done
long time ago we had to do this when i was a helper , and they filled in the spaces with some product to keep it for sounding hollow when you walked on it
or would double plywooding suffice, maybe putting rafters closer than every 16 inches too?

and suggestions?

You could just build it like normal and then use structural spray foam under the joists.

Also, if it is built properly, it shouldn't squeak any more than a normal floor. I'd insulate it no matter what you do.

Run 2x6 joists (rafters?) 16" O.C. yes. These floors are so easy to make solid, by shimming every 3-4'. Use subfloor adhesive. Rip a 2x4 or piece of treated decking tapcon'd and glued down. Then regular shims, with glue and nail (screw) through joist. A row or two of solid bridging may help too. This with filling the bays with fiberglass batts will take you just about as close to concrete as can be done. They always sound and feel different, because it's not concrete.

2x6 with joist hangers. Support as mentioned above. No way I’d use concrete.

It is real hard to use a bull float indoors with walls, then end up with a nice transition, ask me how I know .

Ledger board of 2x6 all around the peemiter, secured to studs with LedgerLok lags. 2x6 floor joists set into hangers. If the span is bigger than eight or ten feet, scrap pieces of treated 2x4 secured to the sides of the joists reaching down to touch the subfloor and provide mid-span support.

Done it dozens of times over the years. As long as the ceiling height can accommodate the higher floor, works perfectly. Slap a vapor barrier and insulation down before you hang the joists. Done.

thats the problem
and i`d have to either get a truck in or rent amixer , and mix it all myself
if i start all that , a good chance the city code enforcement will come along.

they just dont want it to sound hollow.
i`m thinking i`ll insulate , and double plywood it .
maye put rafters on 12 center

What are you pouring over? Is the sunken area a concrete slab? or is it wood framing?

I assume it's concrete and you aren't going to pour over the wood framing. Not that it can't be done, but......

i`m planning either way to put plastic down ( moisture barrier)
and use 2x6 "RAFTERS!!/JOISTS!/RUNNERS!!.
with side blocks tapcon`ed down .
insulate it
and glue and screw /4 inch plywood , then put engineered flooring to match existing ( client has plenty of the flooring . previous owner was a builder and left them extra.
they just don`t want it to be hollow sounding when you walk on it

Crews and companies I've worked, would have gotten laughed off the job for being, well (politely) an idiot. And if lucky viewed as an oceans (wet) behind the ears greenhorn.

This day and age it's just good know someone can differentiate between 2x4 and 2x6 even if they aren't 2", 4" and 6"
