This might be a long post…
:twisted:
Luftweg,
I looked again for that TV show and could not find. My wife said it was most likely on TLC. There was a house infested with bats on the 1 hour episode as well. I think it was a “1 off” show and is not a regular program which is why I could not find it.
:roll:
Steve,
Thanks for the drawing.
:D I’m sure that would work however I already have a building department approved plan for footer and like Keith keeps saying the new footer I’m going to build is not the concern. It’s the edge of my existing patio slab where it meets but is not attached to existing concrete block wall and that walls footer. This is the same wall I’m planning on filling cavities with sand.
I can't go out another foot, I have an exsting roof above this whole thing I am planning to use and as is I'm on my 8 foot set back from property line.
I suggested under pouring to arctitects and the 3rd one (who I've not even mentioned) said to Peter that under pouring an entire footer would be impossible. Would an inspector let this pass? How could I be sure concrete would all get under there. This is why they went with below plan... they skipped on partial under pour which does make sense.
BTW why I'm pouring a footer along my entire patio edge I have no idea when I only need one under new walls.
So we all get on the same page at the end of this post I’m going to attempt to pull all info about the slab into one spot so we don’t have to sort through pages of this thread to get the picture. Hopefully this will be easier on Rod too.
:D
Keith,
As always thank you for keeping the keen eye.
:mrgreen:
I had a conversation with my wife tonight. She is 7 months pregnant now, baby is due in 2 ½ months, the last week of November. Although not likely she could go into labor early, could even be this week who knows and I’ll repeat it’s not likely. I should be prepared right?
Below is a picture of the baby’s room. Can you see the crib in the picture? It is there, full of guitar shipping boxes, behind the elliptical exercise machine.
All that stuff (Xmas decorations, things I need to eBay off, old gear, wife’s school books, junk, etc…) belongs in the garage (or out of the house or in the garbage).
As well here’s a pic of my front door/entrance. This is my PA & lights for bigger gigs, not my smaller solo rig. This stuff also belongs in garage.
Progress:
Today I got the last of the drywall up on garage side of only built walls (so far).
In the USG drywall manual, they suggest using a homemade 2x4 “T” to help hold drywall up to ceiling, if you don’t have one of those fancy drywall lifters like the customized one I keep seeing floating around California. I do plan to rent a drywall lifter later, but today I had one piece of drywall 76” wide, 48” high, 3rd layer to put at the top of a wall. This was my last layer, wanted to get it done and I was alone. Tried briefly and I would say stupidly to hang the piece without “T”.
The T worked great, except for getting T into position. I gently dropped/slid drywall down the wall on 1st try. Only slightly damaged corner of drywall, it was no big deal. Mistake was starting with the T behind me, with in arms reach and leaned up against ladder. The only way I could figure out to do this solo was to lift the drywall while I had the 2x4 T held between my legs. T has to come under drywall while you maneuver your hands out of the way. T ends up at an angle and wedges drywall into position. Following pic shows just the T holding drywall in spot, the screws in pic I placed in drywall before lifting, just in case I needed to go quick.
Now these walls just need corner work, more mud and sanding till there reading for paint.
My make shift 2” putty knife on a pole for getting caulk into the ridiculously tight spot between air handler and new wall. This method is not fun, how ever slow & messy the process is… it works. It even got caulk into the 1 ½” space, way down in the bottom corner.
The patio slab:
Question is:
Build as my architect has currently designed it
OR
Remove part or all of slab under studio area OR use some other method to make me not worry about edge of slab next to concrete wall which inner leaf will sit on.
I do not want the slab to crack someday, ruin isolation, maybe crack walls and displace my eventual hard wood floor (even though it’ll be a cheap laminate).
Other consideration is: this room built with current plan will sit on 2 pre existing slabs which are not level with one another. I’ve yet had the time to figure out how I will level floor if I do not remove and replace at least the patio slab side which is lower and grades down 2” from the garage slab to outer edge. Plus there are hollow concrete blocks which used to be footers where the 2 slabs meet.
SO architect’s current design, which does meet code, this has passed building plans examiner:
Layout of storage room:
Foundation notes:
Foundation Plan:
Close up, cross section of footer:
For comparison sakes the closest footer in Rod’s book to the one currently in my plan is on page 43, Figure 4.4
Differences are:
Purpose, Rod’s footer is basically for creating an isolated slab with new footer. Mine is for meeting building code in Florida for exterior walls. The methods are very similar…
Rods footer is 2’ wide, mine is 1’.
Rod extends concrete of footer under slab it’s supporting, mine is tied via drilling horizontal into old slab and placing rebar with epoxy.
Rod uses a binding agent between new and old concrete. Mine just has rebar and although not in plan architect says place 15 pound roofing felt in between my new and old concrete. He said something like “concrete does what concrete does” the felt is to keep the concrete separate so that old and new concrete do not crack each other. This is not an expansion joint.
Please note I am not trying to obtain an isolated slab, I just want a slab that will be structural sound enough to place all my walls.
The existing condition of my slab is I’ve already cut 2’ x 22’ of the edge of my patio because that’s what my plan says to do:
Now the concern:
When I removed the 2’ x 22’ edge of concrete I was surprised how easy it was to remove the end pieces from concrete block wall/footer. Sharward did not expect them to be attached in any way… but some how foolishly I still wanted to believe my architect saying this slab was connected to the walls.
This has made me concerned about 2 spots:
This is where I plan to put my walls:
Repeating some info (so it’s all in one place):
All pieces of slab I took from edge were 4" min thick; some of it was 5" and 6" thick... I can't confirm whether the rest is actually this thick with out drilling BUT, I suspect it is 4" min all around.
One of my previous pics shows some wire mesh that is 6" squares of wire mesh all under slab, however that mesh I highly suspect is not attached to any wall.
This slab grades downward from the wall I removed to edge I removed. I could guess it may be thicker as it gets closer to the removed wall.
Weight summary of my inner leaf walls and ceiling:
Lumber = 750 pounds
2 layers 5/8” drywall all around = 2400 pounds
Inner leaf frame weight will be well over 3,500 pounds when adding in caulk, drywall screws, mud, wall insulation, interior acoustic panels and flooring.
The total length of all 4 inner leaf walls is about 48 feet. Of this 14’ or so will be bearing on old patio slab 4” thick, which I know is not attached to existing walls. That’s about 30% of the total weight of inner frame or just over 1000 pounds, bearing on 14’ of bottom plates 3 1/2"s wide. SO that's 1000 pounds on 4 sq ft... 250 pounds per square foot.... 20 pounds per square inch.
NOW, I really don’t know if I (we) are over concerned about this or not. 3 ½” concrete is suppose to be 2500 psi. Would make sense my patio slab concrete should take 20 or even 50 psi, however it’s the edges not attached to existing walls which put it all in question for me...
Crazy thought
:twisted: would be to drill at a 45 degree angle from slab into the wall and epoxy in rebar… but that seems real crazy.
If I were to remove the rest of patio slab I would either tie new slab to CB walls and horizontally into garage slab OR pour footers for inner walls OR other ideas are welcome.
I could remove some of garage slab too however I am really not seeing a need to go that far.
The part of this that sucks is that I did not expect to have to deal with concrete, thought I was only going to deal with lumber, drywall, electric etc... all of which I complusively studied months ago. Now I am having to find the time to crash course myself reading about concrete and can't start a darn other thing till I'm sure of the course of action.
