building cinderblock wall... questions questions questions Answered
I'm considering building a small cinderblock wall off of an existing concrete slab. I have very little clue what I'm doing, but I'm a fast learner.
Do I need rebar to hold the blocks, or is mortar mix enough? They won't be "weight bearing" as it will only be a partial wall around 3' tall. If I do need rebar... hammer drill? all the way through slab? pound rebar in? Note that the blocks will be just about flush with the edge of the slab.
The area I want to create a wall for is covered with a roof (four- 4"x4" posts, about 10' x 12'... roof is around 12' high) so the blocks will butt up right next to wooden posts... is this kosher? I guess in my mind, this precludes a cornerstone, and makes the courses hard to offset (I don't know what to call that... the center of the second course blocks sit on the edges of the bottom course blocks), and what is a good way join block to wood?
Can I use the small blocks (4x8x16) or will they just topple over (see question #1 again), and if I should use the normal cinder blocks, how do I make a corner with 4x4 posts already there?
...likely more questions to come :)
