Forum Title: Filling Webs In Block With Spray Foam
Doing some repair on my own house (damaged rim joist)wondering if good practice to fill block webs above grade on last course with spray foam to keep chimney effect down,have 1 rigid foam on unfinished basement walls(no vapor barrior) bellow grade.Noticed moisture buildup at rim area(house has no p.t.plate.)Run a dehumidafier and never had any sign of moisture problem before,just think that moisture vapor can not escape to inside so it moves up to last course of block where it escapes to exterior.foam has been on basement walls roughly 4 years
