Repair or rebuild a block foundation wall
A cracked block foundation wall doesn't always have to come out. If the footings are sound and the crack came from water pressure that better drainage can relieve, foundation repair plus fixing the drainage is usually the smarter money. If the footings sit on soft ground or the wall was never built for the soil against it, patching just hides the problem. Then I'll tell you to rebuild, because I'd rather fix the cause than the crack you can see.
