My husband and I want to build a concrete wall (and finish it with
stucco) on the windy side of a concrete slab which we intend to make a
patio. The wall will be 20' in length by ~5 ft tall. Have a number of
questions to which we could not find answers on the web or in
literatu
- do we need rebar in a 5 ft high wall?
- how do we attach the wall to the house?
- can we just start laying block on the slab or do we need to put some
kind of footing in?
- the cement slab has a crack in it cause by a tree root nearby (we
think), will this cause the wall to shift or crack, could we span the
crack by say laying every other block on the bottom row?
- we live in central WA where the temp ranges from -20 to 106 (last
week), do we need to use special mortar or do anything special because
of the temp fluctuations?
- any other advice?
Thanks in advance.
