90' wide window well?
I need to replace a rotted railroad tie window well which is 90" wide. But only 24" into the ground. Iv searched high and low for anything this wide and now understand why it was built from railroad ties in the first place. I even searched for corrugated silos to use a half round section but have not found the 90" diameter and am unsure about how to fasten it to the foundation.
Can anyone give me a source or a recommendation?
