Professional Structural Drying in Saskatoon

Structural drying follows IICRC S500 psychrometric protocol. Equipment loading — dehumidifiers and air movers per square foot — is calculated by Class (1–4), where Class 3 events (water saturating walls above the flood line) demand the highest loading ratios. LGR (low-grain refrigerant) dehumidifiers are the primary tool for most losses because they maintain high moisture removal capacity across a wide range of humidity conditions, typically achieving a grain depression of 50–100+ GPP (grains per pound) between inlet and outlet air under optimal conditions. Desiccant dehumidifiers are deployed in cold environments (below approximately 15°C) where refrigerant units cannot achieve efficient condensate formation, or when very low final moisture content is required. The drying curve — a daily log of temperature, RH%, dew point, and GPP — is the primary evidence that drying is progressing on schedule. Target EMC (equilibrium moisture content) for structural wood framing is 9–14% MC depending on species and regional norms; we do not remove equipment or issue clearance until readings confirm this target across all monitored materials.
