Attached garage without footings?


Joe Carola -

Just a clue, you are referring to the Republic of Wisconsin, as it was referred to a few years ago in a friendly way. They are famous for adding local conditions, but not always enforcing them. In the past they would poorly change the model codes and not realize the loop holes they created or that prevented some nationally known products from being used.

I am not far from northern Wisconsin and am there frequently. The knowledge and affect of the codes are hit and miss situation. - Good people, but poor administration and controls from the top.

Attached garage without footings?


Ok here's the way it's done in northern Ont. Canada.
First your building dept. will give you what is required
in your area. In my case it required an eng. drawing of
the slab showing how it was to be done. This drawing
showed all insulation that is required around the slab
and under it, pinning to the existing building ect. It
also must be heated to a min. of 40 F all winter.
If there is little traffic around the garage the frost will not
be a problem.
By the way the gentleman that said clay does not move
is out of his mind! It;s the worst there is! I've seen it heave
2-3 feet.

Hope this info is of some help

In alot of the more rural areas of N. WI, there simply aren't building departments. Until maybe 5-8 years ago, most of these areas didn't even require building permits for new dwellings, much less remodeling, additions, alterations, etc... The state passed legislation requiring the entire state to require building permits & subsequent inspections at that time, but most areas never put together their own depts, so the state supplies them with the inpection companies. It's put out to bid on a multi-year contract, and the results are less than stellar. Oftentimes, the independent inspector is onlyy available 1 day a week, they can be very un-responsive, and typically won't help guide you along the way. They often feel their job only entails a "pass or fail" inspection, and it's up to you to do the legwork.

See Dick, here we refer to it as "The Peoples Republic of Madison", as what happens there usually doesn't represent the balance of the state accurately. We do indeed have some differing "opinions" from inspectors on code issues, but they are fairly uniform from area to area.

The comment that clay moves 2 - 3 feet likely refers to silt. Clay is a mineral that tightly binds water to it chemically. The water in clay is not free, and cannot freeze. Silt, on the other hand, refers to small (less #200 sieve) particles which do NOT bind water tightly. Silt is notorious for frost heave, as is very fine sand.

Unfortunately, silt and clay feel similar, and in some cases look similar, hence are often confused. There are sections of the US that have "red clay", which is often silt. So my point is that true clay almost never heaves, but since silt is often mistaken for clay, clay gets a bad reputation for frost heave.

I live in similar weather conditions and built an attached garage with the slab and footings done in one pour. I dug a perimeter trench and formed up the outside with 4, 2X8s.
In my case, for whatever reason, the slab dropped about 1" on the side adjacent to the house.
Fortunately, the slab had fall, so now its just about level.
I would never, ever use this method again. The slab should be supported on piers in our climate. The piers must have footings that are 48" below grade.
