It depends on the depth of the water. The hydrostatic pressure increases with depth.
should be at lest 4 inches
4 To 6 inches
It depends on the application. For homes, masonry is fine as long as it is insulated well against the weather. Masonry rarely needs maintenance. Concrete walls are stronger and last longer than masonry but are more costly to construct. For basement walls, I suggest that you always use concrete walls. Above ground level, masonry is cheaper and strong enough for residential and commercial, multi-story applications. For retaining walls, 8" thick masonry works well up to about 8 feet of retained earth. Above that, the lower courses of block will get thicker to 12". You still need concrete footings for block walls.
With concrete and precast concrete you can build fences, walls, concrete sound walls, pre-cast concrete perimeter walls, masonry walls, masonry screen walls and more! If you are interested in having a concrete or precast fence, perimeter, sound wall, masonry wall or masonry screen wall, then go to the links below for more information.

So that any radioactive material won't get outside and potentially harm other people. For example, that's why dentist's offices are lined with lead and you're given a lead apron to wear for x-rays.
