The Auger borings are not common

in soils that require lateral support

The loose pockets in soil mass can be bridged safely by providing a raft foundation provided the soft area is smaller than

three-fourth the column spacing

one course of headers to three or five course of stretchers

queen closer in provided in each heading course

the middle course of stretchers is started with a header to give proper vertical joints

the maximum projection of the corbel should not be more than the thickness of the wall

the maximum projection of each corbel course should be limited to a quarter brick at a time

the discontinuous corbels are used to carry heavy concentrated loads

For a wall carrying heavy load on low bearing capacity soil,

reinforced concrete bed is provided

Stud(s) of a common wooden partition
