Been working on remoddeling the garage. Previous owner pretty much abandoned it. Figure I need to level out this cement floor before framing up the final walls and flooring.

Would a self levelling compound be the trick to get this done and just pour all over the garage , or any other ideas / recommendations ?

Depends if you know whether the slab has stopped settling (or heaving, if that's what it's doing).

 

[Dizzy88]

How can I determine that ? Slab has been in same position for about 8 months now since I purchased the home.

Depends on where you are and what are you using it for. You said you are building walls? So it's for people use inside? If it is for a car, I would not suggest a self leveler. Freeze/thaw?

I think I saw a stem wall which means deeper foundation, but even with one, my guess is all the movement is from water over the years (not water entering the door and pooling which might be what you are trying to seal with the foam?). Talking about outside with the gutters or the yard drainage wasn't properly addressed. Also, the "apron," if longer than a couple feet and then continues into the garage, will move separately than the garage slab (especially if there is a foundation wall, but even if its slab on grade).

I live in southern Ontario right across from Detroit, we get cold winters but not that cold as northern Canada. And summers are pretty warm.

Everytime it rains I get some water on the floor in the garage on all sides despite the fact I spray sealed the foundation. Could this be from the slabs cracked on the outside of the garage door ? I’ve attached more pics

Basically I am trying to turn garage into a office / chill spot , no car will be in there. But I figure if the floor is uneven then there’s no way dry walling and flooring is going to be easy. I want to lay vinyl on top.

That was an open carport before some one closed it in.

The concrete out the side of the garage is a problem for rotting walls.

To do anything properly, it will quickly turn into a money pit.

So its built right on a slab on grade with no frost protection? The foam inside doesn't stop the water from coming in under the sill plate. Or getting water under the door.

Edit: Neal called the carport.

Assuming the original posts have footings at frost depth, he could leave them to support the roof while he put in a foundation for the walls.:smile:

I knew there was something off. In your opinions , what is my most affordable option to levelling the floor and preventing water from seeping in beneath ? Also Neal pls elaborate on the concrete on the side for rotting walls , is there anything I can do to prevent ?

First time homeowner here and just learning by the day. Really Appreciate the help

 

[stadry]

there's no apparent joint between the driveway & ( future ) chill room so no one ever anticipated this project,,, just as likely there's no footing underneath either

 

[Dizzy88]

How would I go about solving this levelling issue ? Am I able to convert these on a somewhat level ground for when I lay floor and dry wall?

 

[Dizzy88]

Few more pics maybe someone can have better idea of what’s going on and how to find solution ... still have to replace the weather stripping on bottom of the door too but that slab slopes down towards the inside of the garage.


Thanks for all insight

See the square holes in the deck, those were the original post footing for the post hat held up the roof. What ever was done after that was all wrong. So with out going after fixing this up properly, anything you do will be just throw more money after bad.

It should be investigated more but the concrete should be removed set it back on posts with a new slab and the wall should be built with a slip joint so the slap can move.

 

[Dizzy88]

Thanks Neal. That makes a lot of sense because I always wondered what those holes were. Is there anyway to build new posts without needing to demo the entire structure ?

The concrete for the posts should have come above the slab so the original posts may have been set in the ground and rotted off.



But it was likely built with beams for the roof to sit in so something could be done to save the roof and most of the walls.

Do you know what the frost depth is in you area. If it is not to deep, It might be worth putting a footing in.

So what are the beams at the top of the walls? Size and length of each section?

 

[Dizzy88]

The frost depth in our area is 25-30 inches but they recommend 4 feet deep for frost guidelines here.

The entire garage is 19 feet long by 10 feet wide. Most of the beams supporting the roof structure are 8 ft long. The beams supporting the roof from foundation are 10 ft. Entire framing was done oddly as well that’s why I gutted the 2nd wall and decided to start from scratch before framing the actual wall structure.

You are mixing up posts and beams. the horizontal beams under the roof structure a ?" wide by ?" high and they are ?' ft long:biggrin2:
They would have had 4x4 or 6x6 posts going down into those holes in the slab, are they still there?

 

[Dizzy88]

Lol ! Thanks Neal I guess my inexperience and lack of knowledge is really showing that’s why I joined the forum I truly appreciate the help and shared knowledge from you and others. I took a picture of the posts and beams that I see on the inside maybe this helps I hope !

When I measured the ones laying on the roof are about 8 ft. And the ones going up vertical about 10 ft

 

[Dizzy88]

Few more pics of the roof / ceiling / those two darker burgundy looking posts are the only two I can see that look like they are dug beneath the concrete. One looks like it’s rotting a bit at bottom.
