Basement drainage: has anyone ever insulated a drywell before?
I just added a new drain pipe to remove excess water from under the basement footing and from a rainwater tank to a garden near the street. See the attached pic, taken yesterday.
At the end of the pipe will be some crushed stone leading down to a drywell.
Question: has anyone ever insulated a drywell to keep it useful for more months out of the year? I have some reclaimed 3″ EPS foam I would like to use.
Details on the drain system, popup emitter for handling bursts of water, and drywell plans so far are here:
Feel free to post in that thread, which addresses the core issue: making a fieldstone basement more comfortable.
