Basement Window Well
Basement Window Well
(OP)
Hello,
I am designing a reinforced concrete basement window well. I have a couple of elementary questions regarding the design, so bear with me.
The bottom of the wall will be below the frost line. The well is rectangular in geometry with side walls extending to the building at right angles. My first question is how deep should the wall extend below grade from the inside of the well? My second question is what should the profile look like at the bottom of the wall? Should it look like a strip footing, or will a straight wall be adequate. The load is nothing more than a small (50psf) surcharge and the at rest soil pressure.

The frost depth needs to be measured from the lowest grade level, i.e. the bottom of the inside of the well.
The bottom of the wall may very well not need a wider footing by design, but check your code minimum requirements and/or the geotech report.

I guess the question, then, is how far does the bottom of the well have to be embedded from the reference point of the inside of the well if extending it below the frost line is not a requirement?
