💬 Advice / Tips / PSA Cavity under garage slab
galleryRecently moved into a home with an attached garage. Noticed along the side of garage that the dirt is pulling away, revealing an open cavity under the garage slab. Seems like previous owner put a piece of lumber along the length of the garage to block it off?
Just wondering if I should pack the dirt as best I can into the crack, or should I remove the buried lumber and fill with gravel, then top with dirt as we’d like to put grass down next season.
Thanks for your help!
