I'm a trustee for a small country church. We have a problem with our basement walls. They are crumbling on the interior side. Not all of them but quite a few of them. The church (probably built in the mid to late 1800's) was moved from it's original location (by horses and logs). They built a basement at the new site, using blocks that were made on site. We have tried using different interior coatings to keep the blocks from crumbling, but have not had any luck.
We are a small congregation with limited funds. Does anyone have any suggestions? The church (Fowlerton United Methodist Church) is located in east central Indiana (Grant county). Any help would be greatly appreciated. Thank you.
