Freeze-Thaw And Road Salt

Iowa gives a building envelope one of the harder annual cycles in the country: deep winter cold followed by hot, humid summers. Water enters a hairline crack, freezes, expands and widens the opening it entered through. The damage accumulates quietly rather than arriving all at once, and over a decade it turns a joint that needed recaulking into spalled masonry and a wall that leaks under wind-driven rain.

Parking decks are where the winter does its most expensive work. Meltwater carries chloride from road salt down into the slab, chloride breaks down the layer protecting the reinforcing steel, and corroding steel forces the concrete apart from the inside. Traffic coatings, sound joints and prompt repair of the first delaminations cost a fraction of what a structural rebuild does.

Severe Storms And Straight-Line Wind

Iowa sits where severe convective storms form, and the wind loads they produce are in a different category from ordinary weather. The derecho that crossed the state in August 2020 carried sustained straight-line winds well over one hundred miles an hour and damaged commercial buildings across a corridor hundreds of miles long. Events like that strip coping and flashing, lift membrane at the edges, break glazing seals and drive rain horizontally into every opening the envelope has. The damage that shows up immediately is rarely the whole picture: a roof edge that was lifted and set back down, or a sealant joint that was stretched past recovery, will leak in an ordinary rainstorm months later, long after anyone connects it to the storm.
