If anyone is bored here is my garage build. In floor heating and in floor hoist.

The plan is to put in radiant infloor heating and a small 5" deep pit for a Scissor lift.

Well i bought a house and the garage floor was shifting pretty bad. 1/2" gaps every where and the right corner sunk over 2". I subspected that there was no rebar or mesh and that the fill was not compacted at all.

Here is the floor plan.

Pex lay out.


The Hoist i ordered up.

Bottom shot of a ford with a 31" spread.

Stang on the lift with a 11 foot ceiling.


Now incase anyone is wondering, i have 10 feet of head room now and im dealing with petaborugh truss there going to redsign my truss so i can gain 1-2' of extra head room sort of like this. Ill post pics of my design idea. These pics are from a guy in the US and they were engineer approved by 3 firms.




Im going to remove all the concrete and a few inch's of sand then im going to compact it down and level it. Then 2 layers of vapour barrier, then 2" of poly insulation. Then lay down the pex piping then wire mesh and attach the pex to the bottom of it with 2" chairs and a 5" concrete pour.

Here is what i started with.


Day 1 I got the keys to the house


Day 2


Day 4

My old man came to help me out. Life saver.Him and my mom drove 3 hours.



Day 5

Day 6

Day 7




Day 9 Well tinkered with it a bit back is a bit sore, I got an idea to speed up the time.




Me and my dad worked our asses off and this is the progress

Day 10 Floor is all chipped up now just to move it out side. Made this jig to sort out the light rocks and big stuff. Worked awsome







Day 12 here is what we have done. Finaly its all out thank god



Day 13 So i started digging out the footing walls,so i can repair them then i can put vapour barrier and insulation.




D14 So i got 3 of the footing walls dug down. tomorrow im gonna chisel the broken mouter out and then next day fix the cracks and skim the wall.
Well went and got $300 of pink LOL.3 Walls are done and back filled.



D15 I got the front door pads removed and dug down and boxed in and rebared the cinder blocks for more strength.





Well started leveling the floor



dad came down to give me a helping hand Thank God

Pit marked out and now time to start hand digging. Leveled and ready to start insulating




Well Vapor barrier and insulation is layed and insulation is layed


Frame work is done for the pit slab.


Rebar and pex piping is layed down and tied up and ready for some cement.




Now i am waiting for the cement truck to get here

Well cement truck was here and i got it all spread and now got to let her dry.




Well the pad has curred and is dry. Time to level it out and work on the rest of the floor.



Floor leveled out




Floor sealed with 6mil vapour barrier


Insulatation is laid down ready for tuck tape


Floor tucked taped and ready for pex holders


Well 80% of the pex holders are down. 320 pex holders and 4000 screws LOL.


Floor with 700ish feet of pex all layed out.




Well today was the day guys showed up to pour the concrete.







Well floor is all pouredI took out a section infront of the garage door about 18" deep for a small entrence ramp







Well right now i am working on the back wall doing the bracing and doing all the elctrical work.Ceiling bracing for the 9 48" lights and air hose reel and light and extension cord reels.




The layout of the back wall.

 

Im jealous man!!! i wish I had the means for all of that. Good luck, all of that hard work will pay off in the end when you can stand back and look at the finished product.

 

very nice work, keep it up. I have always wanted a sissor lift

 

2" ridged insulation locked together forms a vapor barrior, poly is not required and overkill imo.

You should run the insulation up the sides of the footings past the inside slab edge to the top of the slab to minimize thermal bridging. Makes for a tough detail to finish with the insulation showing but you wont lose slab heat through the footing.

Your slab temp is not going to be consistent with the pex layed out that way, there will be a cold spot in between the pit and the garage door where the 3 returns converge. The entire perimeter should be heated first., then the middle with the returns running through the middle.

Sorry to be critical but I don't know **** about welding and construction is what I do. Feels good man to contribute for a change around here after all the lurking.

edit: skimming the foundation wall is a waste of time as well as it will contribute nothing to it's structural integrity. Just fill the broken joints and move on with life.

 

Hey thanks for the comment.

I **** canned the parging on the foundation wall. Im doing 2" insulation on the footing walls with a 45 deg cut on the top then a thin piece of 1/2" on the last 1" of the slab. Im not sure if this is good but 2 engineers told me to do it that way. I have to put up the new pex lay out witch has its own zone for the garage doors with loops tighter at the doors. and the pit has its own zone and then the other half of the garage. I cant get a confirmed answer on the proper way to lay the pex i get 4 diffrent answer and would like some advise if you have time.

 

im trying to find the design that one i posted was no good. The new design has one loop going 6" from the garage doors back again at 6" then back to the right side then around the slab. The next loop goes inside the slab and the other zone has 3-4 loops in the pit slab. Ill look for the pic tomorrow or can i sent you a pic with no pipes and you could advise me on a layout??

 

Very nice! You and your father deserve a beer for the efforts with the jack hammer

 

Hey how much for that hoist??? What website?

 

just curious, why not get the car hoists that have the two columns on the side, and two arms that lift the car up? seems like it would be cheaper and less work. just wondering

 

Maybe better for lowered vehicles..

 

Can you dig the floor down and pour it below the old slab height?

 

Well if you havent found this site yet, someone on HT introduced it to me when I was building my garage last fall and Ive been trolling ever since. Im sure someone over there can help you with the correct way to lay the pex. http://garagejournal.com/forum/

 

Hey guys reason i took the floor up was cause it was cracked and was dropping 2" in one corner. I did not want a 2 post cause with only a 24x 24 the post are big and in the way when its not in use.

The scissor lift when down will lift up any car even if it was 1" off the ground. The hoist was $3000us.

Few guys on garage forum chip up a 90x90" pad and make a pit for the scissor lift.

 

Huh? theres quite a bit of info on that site from tearing up and refinishing concrete to install pex in new and old concrete. More people have done similar projects like this then you would think

 

Thats not what i ment. I know that. Im on garagejournal JBAUTO is my name on there.

Someone asked if you could put a pit in a exsiting old slab. And yes you can go on garagejournal and look there is 5-6 threads on it.

Im doing a 60x60 building right now with work with radiant infloor heating and the way its design is totaly different as there is 6000ft of 3/4" pex witch is over kill.

I know there has been lots of projects like this done.

 

Sorry been gone for a bit. The way you want to install your ridged up the foundation sounds good. For the pex just try to heat the exterior walls first and run your returns closer to the middle of the slab. Lay it out so a loop heats each of the three outside walls. Follow that in principle and you'll be fine. Even if it's not perfect you'll be ok, 1" line is pretty beefy.

 

Understanding wife you got there

 

The more I look at these things the more Im interested. I just wish I didnt have to ship it from china, thats a headache I just dont feel like dealing with. Murphy tends to show up when I do things like that.
For those interested heres a bunch more photos.

I was originally looking at a max jax, but I love the idea that its completely outta the way when not in use.

Eitherway keep us posted once you get it in, I'd love to see the finished results

 

love the lift. in for more on this.

 

More pics up. Will have more pics and info up this weekend

put 1 or 2 floor outlets in the middle "convenience" but not neccesary

 

I knew those were CF combats I double checked your location, and sure enough

My bro is in the Air Force. Engine tech, shipping out to Yellowknife now to work on the twin otter..

 

wow i am impressed. that is serious work there.

 

Lol yeap im chairforce. Im posted in trenton. Im a Plumber in the air force

More pics up tomorrow as we level out the ground

 

lots of labour! All that chipping by hand . That pex heating is nice stuff, my parents have 6000sq ft of it in their new house. Basesment floor, and the main level is a poured floor over ICF. (as well as the walls).

Forced air is history.
