First of all I have searched and read all threads similar to this subject. Thanks for the help so far!
My situation is VERY similar to BayouFrank.
SOG, Living Room sunk 5-1/2", 15'x20'--3 openings, but only 2 may have the same flooring
South Texas Clay ( I think the correct term is Victoria Clay)
Slab repaired 2 yrs ago with 44 piers.
Main objective is to make LR and kitchen same level and same flooring. May be tile, laminate, engr wood laminate, wood, or vinyl wood planks.
Entry foyer and laundry room are part of the project and will be tile/slate/granite (something hard).
Now i need to raise the LR floor.
What I have gathered and learned so far:
- Fill with concrete
- no vapor barrier needed
- no expansion matereal between new and old
- pin to old
- 6x6 wire mess
Concerns:
- Cold joints if I use vinyl laminate. This is a problem no matter which method is used concrete or plywood subfloor.
- extra weight on slab ~15,000 lbs
Is this the correct path or go with plywood and sleepers?
Project so far-- Removed all interior in LR and Kit, cabinets, drywall, fireplace, and a couple of load bearing walls. Two very harding working young men Bosch hammered all the old thinset out(~200 sqft) Took a full day and no breaks- 1 hammered 1 with shop vac). They both got a nice tip.
Installed 2 - 3½x11⅞ Veralams "T"ed together. New ceiling joists. Braced and blocked mansard ceiling. Re-braced roof and ridge boards. Objective was to have a clear span from kit to LR.. Before it was very chopped up. Kitchen ceiling was sagging 1½" at center. Original (hate to use this term)"framers" cut two joist to box in a 2x4 florescent fixture. (Hacks)
It came out great! Hate to cover it up!
