I recently had a mason look at my concrete block basement wall, which is bowing slightly, and has horizontal cracking along the mortar joints. He didn't think it was a problem the way it was, but said he could fix it by digging a little bit around the foundation, drill hole in the block, insert a piece of rebar, and then pour concrete down the drilled hole to fill up that particular cavity in the block. He thought I might need four of these done on the wall, and would charge about $60 for each one. Is this a good fix? Will it work, and keep the wall from moving? The other option was to find someone to brace the wall from the inside of the basement. He didn't recommend that. He believed it would just make the wall want to crack in another spot. I know the first thing to do is eliminate any water problems around the foundation, but I would like to shore up the wall just for piece of mind. I would rather spend $1000 now instead of $10000 a few years down the road.
