Injection / Wall-Cavity Drying System Sizing
Sizes an injection / wall-cavity drying system: the stud-bay count from the wall length and stud spacing, the injection port count, and the number of air-delivery systems - the minimally invasive alternative to a flood cut for drying enclosed assemblies in place. Port count and ports per system are manufacturer-specific; respect cavity contamination and pressure direction; the restorer and IICRC S500 govern.
Formula and source
bays = ceil(affected_wall_ft x 12 / stud_spacing_in); ports = bays x ports_per_bay; systems = ceil(ports / ports_per_system).
Bays-from-length geometry, by name; ANSI/IICRC S500. The stud-bay and system counts are field-arithmetic identities, not edition-bound.
