Re: Dry stacked vs. Mortar I need to build a block foundation, which will be underground. Since I've never laid mortar before, what are the chances I will be able to come out level on top. I am not concerned about the appearance (I'll bury it all in the end), but it needs to be level. What is the concern about dry stacking block for a below grade foundation? Does it allow too much water to seep in? |
