We started a new job building a house near Rochester, Washington. The footprint is 900 sq. ft, but there is also a 100 sq. ft. loft, so the house is 1000 sq. ft total. A few weeks ago they excavated the site and soon after we assembled the form boards for a monolithic pour. A monolithic pour means one pours the footing and the stem wall at the same time.
Here is a picture of Wes and Shon stetting up the 2x6 footing form boards. The footing is 12" wide. I was not there the first day for setting up the layout, but I was there the next day to finish staking. After the footing was all set up, rebar was hung inside the boards. Then 16" pieces of rebar were laid across the span of the 12" footing to hold the forms for the stem wall.
The stem wall is 4 ft tall, so the crawl space under the house is accessible and available for storage. We clipped the form boards, hung another layer of rebar, installed vents, framed the crawl space entrance, squared the structure, straightened the form walls, braced the walls and oiled the inside of the form boards. We had the foundation inspected and we were set to pour.
The morning of the pour could not have been nicer. It was overcast and cool. We got great advice from the pump operator and we used about 12 yards of concrete. We had to insert J bolts in the top of the stem wall while the concrete was wet to hold down the mud sill. Everything went smoothly and we headed home.
