PIT INSTALLATION NOTES
A recessed pit installation is possible when a low outside
threshold is required or desired. For pit installation, the
finished floor must be no more than 1/2" (1.3cm) below the
top of the outside threshold. For easiest wheelchair
entrance and exit, the finished floor should be flush with the
outside threshold of the module.
A typical tile installation will require a 3/4" (2cm) minimum pit
into the subfloor.
An alternative to a pit installation is to build a wheelchair
ramp above the subfloor up to the outside threshold of the
module.
Framing of a wood-framed sunken installation must be
similar to the framing used in stairwells.
The designer or architect should specify the quantity and
size of reinforcing joists and headers.
Size the joists, subflooring, underlayment, and floor
covering to make the finished floor flush with, or a maximum
of 1/2" (1.3cm) below the module threshold height.
