I went in our garage yesterday and noticed that we have frost forming on the grade beam of our garage.
Last year we dug around the side of the garage to put a 4″ corrugated drain in and insulated that side of the garage concrete to 2 feet underground. The part in the picture is not insulated. I was surprised how much temperature difference there was between the insulated and non-insulated.
Next year I’m going to have to dig and insulated the rest before the moisture wrecks the drywall.
