Why older Idaho Falls garage slabs need a moisture check
Half of Idaho Falls homes were built before 1978, the city's median year built. That older stock means many garage and basement slabs were poured before under-slab vapor barriers were standard. Before we quote a coating for one of these floors, a moisture read or a moisture-tolerant primer is part of the conversation, not an upsell.
About 38 percent of Idaho Falls homes went up between 1950 and 1979, according to Census housing data. Slabs from that era often went in without control joints or rebar, so they crack as they settle. We grind those cracks open and patch them before any garage floor coating goes down, and we price that repair as its own line item on your quote.
Idaho Falls winters run cold. Fanning Field averages a 12.1 degree F low and a 28.7 degree F high in January, and a 13.4 degree F low in December (NOAA 1991-2020 Climate Normals, station USW00024145). Freeze-thaw cycling plus salt tracked off tires is what eats bare garage concrete here. Every coating system we install handles salt and freeze-thaw, and a winter install happens in a heated space so it cures right instead of setting soft.
If a coating job turns up a structural slab repair or a moisture-barrier retrofit, that piece goes through the City of Idaho Falls Building Division at 380 Constitution Way, not Bonneville County, and we tell you which office to call. Idaho Falls is a strong homeowner market too: 67.0 percent of occupied homes here are owner-occupied. See our full floor coating lineup, or ask for a free quote.
