(Inter NACHI) Certified Foundation Waterproofing Specialist (CFWS) The CFWS exam drills deep into hydrostatic pressure dynamics, capillary rise mechanisms, and the chemistry of efflorescence formation in masonry. You’ll face detailed questions on polymer-modified bitumen applications, sheet membrane installation sequencing, and diagnostic protocols for identifying whether water intrusion stems from external seepage or internal condensation—distinctions that separate competent repairs from costly failures.
