a footing;
a foundation wall supported by said footing, said foundation wall having a plurality of cells arranged so as to define aligned

of said foundation wall have a cross-sectional shape that is the same as at least some of said cells of a lower row of cells
of said foundation wall, wherein said foundation wall has an interior surface that faces towards the interior of the building

is located have the same size and cross-sectional shape extending along their lengths, wherein said vertically disposed rebar
is a single continuous integral piece of rebar that extends from said footing to said top row of cells, wherein said vertically
disposed rebar contacts said horizontally disposed rebar and is located in said top row of cells and is embedded in said grout
in said top row of cells and does not extend above said top row of cells and is not attached to said sill;
wherein said grout in said set of said aligned cell cavities that includes said seismic strap is located between said footing
and said sill, wherein said grout is completely located within said set of aligned cell cavities that includes said vertical
rebar such that said grout is not visible on said interior surface of said foundation wall and is not visible on said exterior
surface of said foundation wall.
