the concrete blocks in my basement walls inside and outside are disengrating appartnly bad blocks house bult in 1956. I would like to stop further deteration befor it threatens the life of the wall
You are wise to be concerned about the structural integrity of your house. As the concrete blocks deteriorate they will be able to support progressively less weight. You need to stop the deterioration, get an assessment of how strong your basement walls are now, and if needed take some steps to "beef up" your structure so that it will be safe.The only reliable way to handle this is to have a civil or structural engineer inspect your basement walls, estimate the remaining strength and the loads that have to be supported, and make recommendations if structural work is required.This sort of work requires a professional engineering license in all 50 states. You can find such professionals by obtaining references - from neighbors, from contractors, or from cooperative building inspector staff at your local City or County engineer's office.The actual cause of the deterioration should be determined. If the blocks are overloaded that's one issue. If they are coming apart due to chemical causes that's another issue. Sound blocks don't come apart just due to normal water intrusion but even that can be properly handled if needed.Good luck with this situation. Get an experienced civil or structural engineer to investigate and give you a written report with recommendations.
