I'm helping out with a dedign to finish about half of a basement to make a playroom.
The basement walls are 8" concrete block, and the floor is poured concrete with a weep well around the whole basement perimeter that leads to a sump well and pump. The sump pump and well are not in the area where the playroom would be.
The present plan to finish the exterior walls is to first put vertical treated 2x studs as nailers flat on the concrete wall, then mount 3" rigid insulation on the nailers (R15 required in our area), then build a regular 2x4 stud wall against the rigid foam (with a treated shoe), and finally, place mold resistant drywall against the stud wall that will be painted.
The purpose of the initial 2x nailers is to avoid covering the weep wells with the rigid insulation, and to provide some vertical ventilation for the weep well.
Right now, no ceiling is planned .... just the walls and an epoxy-leveled floor covered by engineered flooring specified for this kind of application.
The basement had a moisture problem before the owner bought the house (not water but moist walls), but it was remediated by a basement contractor who installed the sump well and pump, as well as a dehumidification and gutter system that leads to a dry well. It's been pretty dry throughout the unusually wet summer we've had this year.
Does this sound like a reasonable way to deal with the weep wells? Or should they be ignored since they haven't been observed with any significant moisture in them? In that case, the treated 2x's against the wall could be omitted.
Thanks!
