I have little foundation experience but I was asked to build a 24×36 garage with a 12/12 roof for storage/office space. It is in Rochester, NY where the legal frostline is 42″. Our footer will be at 48″ with 7 courses of block. Is there a footer drain and if so where do I tie it into? The concrete and block work is the only aspect I’ve never been involved with.
Thank you for your responses

What kind of soil and how high does the ground-water table get?
What soil will you be using to backfill the interior?

The soil is good earth (not clay) and the interior will be backilled w/ stone for the floor. The grade is level and it is fairly residential so there isn't space to run to daylight
But since you haven't answered about water table, and your profile to tell me what climate you live in is not filled out, I can't guess about how much water you might need to handle. So this is generic, not specific.I know of a garage that was build in wet soil and the infill was stone/gravel. since that functioned asa drywell, all the water from the surronding soils migrated to the inside of the stem walls and humped the slab up three inches in the middle, creating severe cracking.Since you report good soil, maybe you have a chance that water will migrate away from the walls. Maybe you live someplace where it seldom rains.If you have water and noplace for it to go, you need to provide a place for it to go. Perimeter DRAIN AND A SUMP is one way

Missed that. I grew up forty miles from there. It is wet soil and heavy on the percipitation - right in the snow lanes off the lakes, good humus and lovely for farming- but wet. Definitely drain to sump if no daylight available

Like I said, I have little previous fooundation experience. While at work today (I'm a commercial framer doing assisted living developments that are all slab on grade) I asked the site super about this and he said thaat al the water goes down, there are no drains and unless the architecht and the town agree that a retention pond is necessary, the slabs and footings are OK. I've worked on probably 500,000 sq. ft. in the last 2 years that is all slab on grade so I am thinking that the studies have been done locally..
Piff, where did you grow up?
