Thanks.

My intent was not to imply I would not be anchoring the sill plate.
I already know code here and for that matter, probably all of Canada and the States requires anchor bolts.

My question was simply a question. Just curious about what the bolts purpose is. My house has been standing on its foundation since 1967 with nothing holding it in place that I can see.

What I do need to do though is to find out what the load bearing value of my soil is to see if the 16" footing can handle a two storey house with brick veneer. I believe I need 3000PSF for my footing size and the intended application.

Anybody know how they test this?

The times I've seen the soil under footings tested is via a tool that looks like a long slide hammer that rests on the soil. They drop the "hammer" portion X mount of times and measure how deep the rod penetrates the ground, which gives them the values for their evaluation. Not sure how you'd do it on an existing foundation w/o digging it up, or how you'd verify that the footing is only 16" for that matter.............

Interesting.

The footing sticks out 3" beyond the 10" blocks. I would imagine its 3" on the inboard side as well making it 16". I seen this (the outside only) when the foundation was being waterproofed. I didn't think about getting it tested at that time.

I talked to the soil engineer. He needs me to cut out two 24''x 24'' squares at opposite corners in the basement floor and dig out the dirt to the bottom of the footing.

His cost is $500.00 and includes a report.

That is great! I've dug many examine it holes before the work begins, never know what you will find...

I got started tonight.

No point worrying about how to cut back floor joists if I have to end up using real wood siding.

Thanks for this comment. It got me thinking about the extra weight.

I figured it would hold but I'm certain now after the testing.
200 kpa which comes out to 4000 PSF. The chart I found on line for a 2 story wood framed, 4" brick veneered house calls for a minimum 10'' wide footing. Another source calls for 12" minimum. I've got alot to spare so no worries.
