Monolithic or Stem Wall Foundations – Prior to pour, install the
STB or STBL in an upright position and at a 45° angle to the wall. Install
one horizontal #4 rebar at a depth of 4" (minimum). (See illustrations.)
Concrete Block Applications – Prior to cell pour, install the STB or STBL in
an upright position and at a 45° angle to the wall. (See illustrations.) Use the
embossed angle guide on the end of the STB or STBL shaft as a guide. Install
one horizontal #4 rebar at a depth of 4" and one vertical #4 rebar maximum
48" o.c. spacing. Fill all cells with concrete having a minimum 2,500 psi
compressive strength.
