This is the first time in days that the sun has been out. Good thing too; because we're pouring the concrete for the basement today, and it would be a nasty job to do in the rain. The guys from Priority Concrete Pumping pumped 27 cubic meters (72 tons) of concrete into the ICFs... and except for one minor problem... everything went incredibly well.

The concrete was laid down in three lifts (layers); one four feet thick, one three feet thick, and the last one two feet thick. By pouring it in lifts, it minimizes the pressure on the ICFs. If you were to pour all nine feet at once, the wet concrete could exert enough pressure to blow out the bottoms of the ICFs.

The guys ran the pumps and the hose and I followed behind with the vibrator.

The only problem we encountered was when one of the corner blocks lifted a bit after the pour was finished. Apparently it might have been prevented if I had taped up the corners with fiberglass reinforced tape. It's not really a serious problem though, as I can fix it by trimming the bottom off of a couple of the ICF blocks for the main floor - which go on top of these. When the house is finished, it'll be like it never happened.

Other than that, the walls are square and plumb... everything turned out well. Now I just have to clean up the mess of all the bits and pieces of styrofoam and wood.
