I need some feedback on this. I am building a small 1 story room addition in a very heavely wooded area. There are a couple of oak trees that are well over 100 yrs old and some pines that are 75 ' tall.
The problem we are having is that when we are digging the footer the deeper we go the more problems we are having with the tree roots. The concern is not good base soil as we have what seems to be a good soil base at this depth but I can only get 24" to the bottom of the footer below grade as oppossed to 40" that is standard.
Some thoughts, I can't raise the grade in the whole area so that is out, but what I thought is to insulate the footers on both sides and top after block is layed with 2 " foam and raise the grade next to the foundation with landscaping blocks and fill the area with soil.
The downspouts will drain quite a distance from the house so water next to the foundation will not be an issue. Also within 25' of this new foundation the yard slopes considerbly down to the lake which helps with water runoff so that water retention higher up in the yard is not as large a factor for frost levels.
I am located in NW Ohio.
Jason I am hoping to hear from you, you seem to have alot of insight in our area. Sorry I have not been able to take you up on the offer, Just seem to never be able to find the time.
