Masonry Foundation Design

[ganymede]

In masonry type structures with a subbasement level higher than the upper level of the foundation, is it necessary to make a curtain under the walls in order to establish a connection between the load-bearing walls and the foundation? Brick on the curtain, with the curtain on the foundation. Otherwise, the masonry brick will have stepped on the pavement on the fill. I would be glad if you share your opinion. Respects.
