![]() The wall is held in place by stone on one side, and dirt on the other. The block on my foundation is 42" tall and is above grade only 8-12". There are some scenarios where you don't need to core fill or you don't need rebar. I think it would be more work.ĭefinitely a free standing stem wall of 9' with 8" block needs rebar and concrete core fill. Your interpretation about laying block without mortar is the same as mine. I can see how adding concrete would make the wall 100x stronger.so why wouldnt people fill their cores with concrete? I imagine without rebar, the force from the tractor would not have spread evenly through the wall, but would have instead broken the blocks that were directly in contact with the tractor bucket. As the mini excavator bucket pushed the wall, the wall bent, but did not crack or break anywhere, and went back to its previous form as soon as i moved the bucket. The stem wall had mortar joints and all the rebar in it, but no concrete. When i was building my 9ft tall cinder block stem wall, i accidentally pushed the wall with a mini excavator bucket as i was trying to dig some of the dirt out. Of course they are using mortar to lay the blocks, but it seems to me like not having your cores filled with concrete would make the wall extremely weak, especially a stem wall thats over 8ft tall. ![]() Is this correct or am i missing something?Īlso, I have heard of people not filling their blocks with concrete, but using sand instead. Without mortar, you would not be able to adjust for this. ![]() What strength does mortar add to a wall? It seems to me mortar is primarily used to make it so you can adjust the leveling/spacing of the blocks as a typical foundation is not going to be perfectly level, and cinder blocks themselves vary slightly in length/height. I have heard of people not using mortar to lay the block, but instead dry stacking them, but filling every core with concrete/rebar. I have a few questions about cinder block stem walls.
