R608.4

Section R608.4 is titled 'Stay-in-place forms' and covers requirements for the use of stay-in-place forms used for placing concrete and which may also serve to provide insulation for the foundation walls. This section contains no technical language, but establishes that its subsections must be adhered to which contain technical criteria that stay-in-place forms must conform to and methods of protection. The purpose of this section is to slow the spread of fire and prevent premature degradation of the forms from sunlight, physical damage, and termites.

The model shows sections of stay-in-place forms - one is made from rigid plastic, and the other is made from expanded polystyrene with plastic cross-ties which also serves to insulate the wall.
