Stem wall opening width for doors

[deepstuff]

Finally pouring!! When I pour my stem walls, do I leave enough space for wood framing to extend down into my door openings. a 10'-3" wide opening for a 10' foot door etc?? I'm building wood framed 10 foot high walls on top of a 8" stem wall. Not sure if stem wall is the term to use but I'm going to have a ceiling height of 10'-8". Walls will consist of 8" on concrete on the bottom then 10' of wood.

Thanks

I left the stem walls the same rough opening as the framing.

It depends..

Your inside needs to be flush all the way around the door opening along with the vertical track and spring mounts. If your foundation is 8" above the garage floor your bottom stand off bracket will most likely need to be lagged into the foundation. Whether you hold your foundation back (which I prefer) be sure and leave at least 3" per side or Stay flush with the foundation doors can be installed either way. I just charge more to lag to cement.

As long as your flush all the way around and for all your mounting locations the rest is preference.

The classic way is opening plus 3", which is 2pc of a 2x timber used to trim out the door opening.

However that puts wood down against the ground, the bottom part should probably be treated or at minimum latex painted on all 5 sides for a foot up.

I built my shop with the concrete walls (8" higher than slab) to nominal width only, knowing its doing to be some tapcons or track bracket modifications to work out right. The tradeoff is no wood near the ground.

3" each side - a 10 foot wide door would require a 10 foot 6 inch opening between the stem walls.

Unless you are planning to hose out the floor often, stem walls are not usually necessary. But living where you are, perhaps consideration for snow from the vehicles being parked inside is a concern, if so will you slope the floor for drainage?

Yes garage will be 44' deep. floor will be level in back half of building but slope towards two floor drains in front half. Snow meltoff is a concern so is the biggest reason for stem walls. Also will hose out sometimes and will be welding in garage so want to be able to kick something hot into corner (just in case).

Your door install directions will have this information.
