40 year old split level house. We've been in it 15 years but didn't notice this until we had an old addition removed & expanded and the kitchen redone where we pulled out the old vinyl flooring and countertop & replaced with a tile floor & silestone countertop. The addition was done 1st, later when the kitchen was pulled apart I noticed that around the sink area the floor sagged compared against the beginning of the addition. Maybe 2 inches at the worst part. Now we've noticed the floor tiles around the sink area coming loose. I'm thinking it's because the floor is sagging a little more with the extra weight of the new kitchen floor/countertop etc.
Below the kitchen is the basement - 8ft high with cinder blocks wall. Floor joists are 2x8 spaced 16 in apart running from the front yard to the back yard. They extend about 3 & 1/2 feet past the cinderblock wall. Above the kitchen is the attic.
Last summer I went in the crawlspace under the addition and underneath the part where the floor joists extend, I dug 3 holes in the center of the space, 4 feet apart and about 2 feet deep and fiiled them with concrete on which I put a pair of cement filled blocks and a pair of pressure treated 2x6s. Mainly for peace of mind to help keep it from sagging any further. But that area just stopped short of where the sink is where I notice the most sag. So I was thinking of going back under to do the same thing in the 6 foot span next to where I left off.
Is this doing any good to help prevent further sag?
