So now I'm stressing! I put cinder blocks in a foot or more of concrete yesterday afternoon. It started raining hard last night. Let up for this morning and is pounding rain again. When I got home today I went ahead and set a cap on top of the filled blocks (no mortar, just to keep the rain away), but the rest is exposed. Will all this rain weaken my concrete?!! Someone please answer or I shant get any sleep tonight!
