Crack on the concrete sub-floor
Comments (2)It's hard to tell from the photos, but could it just be a cold joint? It looks awfully straight not to be. This is where two slabs butt up to one another, with the first slab dry and the forms removed, and then the second slab is poured right next to it. From the pictures it looks like one side of the crack is pretty straight and clean, and the other side is more jagged... is that right? If this is the case, you probably have nothing to worry about... but it's probably not a bad idea to get real in-person opinion!...See MoreLong diagonal crack in my concrete slab floor is scaring me.
Comments (3)msgreatdeals, Thanks for your reply but I wish I read this first before sealing the 47 foot long crack (found some places were 1/4th & 1/2th but most of the crack was 1/16th & 1/8th wide)with flexible DRYLOCK masonery crack filler. Then I started to use the filler to fill in small holes in the three rooms but some of the bigger holes that were formed from removing the clumps of plaster that was not level or from removing the tackless would not fill so I went in the garage and found some cement filler that my friend used to fix the step going from the garage to the middle foyer. I wish I used this only for the holes. I hope I did not mess up. The installer has not called me back and I want him to arrive tomorrow ready to install the floor and not fixing the floor and not being able to finish and then the project dragging into next week. msgreatdeals, thanks for sharing about your concrete floor also. I hope your floor will be OK also with your epoxy repair. I did have some water damage from a leak in the Poland Spring Water coolor about 10 years ago. that is where the crack had started. I forgot about that! But all in all my concrete floor was very dry. There were fine cracks in the concrete floor in other places but they were small but I still used the sealant that is flexible to seal them also....See MoreFloor level survey for cracks
Comments (5)Here are some pictures: This is the main (largest) crack in the house, on the kitchen ceiling. It is approx 1/8" wide and runs across the ceiling, starts diagonal for about 4" at a corner and then moves along between wallboard sheets across the room (about 8 ft). This is the second most significant crack, adjacent to the previous ceiling crack (about 3 ft away). Here you can see clearly from the marks that there is a relative shear movement beween the wallboard sheets. The marks show past alignment from about 10 years ago on 11/1998 and 1/1999. As you can see an additional 1/16" of movement has occurred since. However, I have watched this crack over the years and it seems to move about 1/16" up and down, perhaps with the change of the seasons. The peculiar thing about this crack is that it is most prominent at the ceiling and almost vanishes as you move closer to the floor. I have checked the foundation (perimeter foundation) in the crawlspace below these cracks and I can see no cracks/displacements in the concrete. I do though need to mention that on the ceiling of the bathroom immediately on the other side of these cracks there is evidence of water damage on the ceiling, I believe an old roof leak (previous owners) must have caused this water damage since there was still a small roof leak when I moved in the house (I replaced the roof shortly after I moved in) and the old roof had signs of having been patched many times. And finally, this is what I would consider the 3rd most prominent crack in the living room ceiling. There are a few other cracks throughout the house but they are minor normal, I thought, cracks that one may see in many older homes....See MoreWhat is Best Way to Get a Large Concrete Garden Column Back to Level?
Comments (15)Some good suggestions so far, so let me propose some specific things and how could I finish these ideas: 1) For the base, what about using an 18 inch square paver that is two inches thick and built for thousands of pounds of weight. Secure into that paver base some concrete bolt anchors, around the perimeter of the column's base. The the question would be is there something I can use other than a concrete bolt to screw into those anchors? There must be some part that is made that would hang over the top lip of the column base? If the column tips it would have to displace the entire paver. I would do some work to make sure I have enough weight on the paver to resist against the forces from the column. 2) For the pot, I could bolt that in but getting that off then becomes a nightmare. Would using some kind of silicone help at all? 3) Something that is not clear in my photos is that the top of the column is removable. I should do something to secure that in place as well. Would silicone work as well?...See MoreF B
