Storm & Overland Flood Damage Restoration in Saskatoon

Overland flood water that has contacted soil, municipal drainage infrastructure, or sewage systems is classified as Category 3 (highly contaminated) under IICRC S500, regardless of visual clarity. This classification mandates full biohazard protocols including PPE, containment, and removal of all porous materials that contacted the water. Storm water intruding through roofing or above-grade openings before ground contact may be Category 1, but migrates toward Category 2 or 3 as it travels through building assemblies. In multi-family and commercial structures, smoke barrier and fireblocking penetrations frequently act as conduit paths for water migration to areas well removed from the entry point. Wind-driven rain intrusion in particular requires thermal and moisture imaging to map full migration extent because water can travel horizontally across multiple bays within a wall assembly before gravity brings it to a visible point.
