Crawl Spaces Built to a Base's Schedule
Chanute Field operated from 1917 to 1993, and buildings constructed to house that 76-year technical-training mission weren't built with today's crawl space moisture standards in mind. Civilian redevelopment on former base land since 1993 has introduced a more modern construction generation alongside that older stock.
Encapsulation Needs Across Different Building Eras
A crawl space beneath base-era construction has had far longer to accumulate ground moisture and settle than one under post-1993 redevelopment, so the right encapsulation approach can differ significantly by which era a Rantoul property belongs to. That distinction is worth establishing before assessment.
