Cold garage floor

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.

 

Update to cold damp basement

Now that winter has arrived with -34 Celsius temperatures it is a good time to revisit the changes made to the return air path in our basement.

The picture says it all the upstairs and basement are now the same temperature.

I will still put an extra return air vent in the basement when we build some walls, but for now all is good.
