When to worry about a cracked foundation?

 Nothing wrong with stupid amounts of rebar !

relatively cheap to install on day one - not use enough and down the road the repair bill will be way higher !

Sorry for the stupid remark!  I am a huge fan of rebar in concrete and often use more that they want or suggest.

I sort of meant the stupid remark as one of those kids sayings like it is so cool its sick    Tire store last year!  Again 

The one thing in the house we are building.  We hope and want to avoid passing on to our family some day a house that is falling down around their ears.  It is engineered and being built as such.  Something we will be able to be proud to pass on or sell at a premium price.

If I'm digging out a chunk of the footer, like one entire side, should the new one somehow be connected to the rest of the existing footer?

It would be best too

Drill and resin in rebar or allthread- make the existing surface rough as possible

The bricks above too- try and dove tail the joint by cutting out every other brick verticly

I am getting ready to have this foundation dug out and repaired, and am trying to figure out the timing. The plan is to:

- Jack up the back of the cabin an inch or two.

- Have a backhoe dig a trench around the damaged part of the foundation where the walls are cracked and footings suspect. This is about 1/3 of the total perimeter of the basement wall. Backhoe busts out and removes damaged wall and footings.

- Pour crusher run in the bottom of the trench. (What depth? Will it need power tamping?)

- Pour a new concrete footing 4 feet down (Northern NY near Canada border). Tie this into the existing footing somehow.

- Have a block mason rebuild the wall, filling the block cores with rebar and concrete every few feet.

Since I will only be able to go up to the property to supervise this project a day or two at a time, usually on weekends, one concern is how to protect the trench from heavy rain during the week or two that may elapse between digging and pouring.

Any suggestions, or red flags?

Thanks,

David
