Crawl Space and Floor Structure Defects; Recognition, Causes, and Cures

Residential crawl space foundations and floor structures are affected by many external forces, poor construction and blue print & design discrepancies. Recognizing movement & forces within a crawl space foundation and determining what is happening is sometimes a challenge. Techniques of crawl space inspection will be presented that help in the detection and recognition of crawl space foundation and wood floor structure defects and failure.

Guidelines will also be presented that help in determining the severity of crawl space movement; whether cracks are just typical or structurally significant; as well as floor structure “Rules of Thumb” for beams, columns, and floor joists spacing – spans. Techniques of structural repair and their effectiveness will also be illustrated.
