Basement Crack Repair
How can I fix my basement wall? It leaks and has some cracks here and there.?
We took care of one side of the house. The driveway slopes to the house and so the water was getting in there through the cracks. For a quick fix now we tared the outside and we haven’t had a problem since then. In the front and back of the house we built up the dirt around the house to keep the water running away from the house. So now our problem is the other side of the house. We have a cinder block basement and it’s starting and/or is pushing in. I could probably grab the block and pull it right out. We’ve had a numerous amount of basement repair people come in and give us estimates ranging from 8 to 17 grand to fix it. I’ve had people tell us we could replace it on our own. So I was wondering if anyone had advice on how to do this? Other people have said to take a few blocks out at a time and replace them and then tar the back of the wall. I know it would be best to have a professional do it but if we had the money we would.
If your only problem was a leak in the basement wall, I’d recommend a repair using injected bentonite, which is a naturally occurring mineral that swells up in the presence of water to form a watertight seal. It can be injected from the outside around the perimeter of the basement wall, without having to excavate the backfill. The application, however, requires specialized equipment and should be done by a professional. Volclay Bentogrout is one product that is widely available:

However, it appears that your concrete block wall is deteriorating. If the block wall is the foundation for your house, you’ve got a serious structural problem that must be addressed, or the house may collapse. I can’t tell from your statement if this is the situation. If so, you may need to call in house movers to support your house while the foundation is rebuilt. Reinforcing steel (“rebar”) should be used in the concrete block wall, and the cells should be fully grouted. This is not a job that can be done a few blocks at a time by a homeowner. I recommend that you have a licensed structural engineer examine the basement wall and advise you how to proceed. His consulting fee should not be too expensive, and will be money well spent.
