Christmas 1988 |
With the permitting process behind us, we were excited to get
started framing our new home.
For Christmas that year we gave each of our six children a hard hat and their personal hammer. We wanted them to feel a part of the project.
But before we could begin framing, first the foundation had to be done properly. We outlined the footings on the building
pad. It sure looked like a small house
as we gazed upon the footprint from up the street.
I rented a backhoe. I
think my brother, Don, did most of the digging, but I probably took a turn on
the equipment. I was surprised that not
only did we need the trenches around the outside of the house and down the
middle where the bearing wall was to be built, but there were substantial
footings under the stairway as well. We also had to trench for the underground sewer lines, and install the sewer pipes before the form inspection.
We were doing the footings and forms in the month of
December. I was too cheap to rent a
porta-potty, so we would drive over to the park, about a quarter mile away,
when necessary to use a restroom.
The southwest corner of the house required a combination
retaining wall & footing. Rather
than spend a lot of extra money on hiring an engineer to design the retaining
footing, we opted to use the county approved design that had an oversized
footing that required lots of rebar (steel reinforcing bars) and lots of
concrete. The base of the footing was 3
feet wide and 3 feet deep, plus the 3 1/2' concrete stem wall above it that retained
the dirt on those two sides.
We had a couple rain storms during the forming process, and I
remember having to bail out the water so we could work in that deep and wide
trench.
We borrowed electricity from a neighbor across the street so
that I would not have to pay to put in a temporary power pole. We ran a long extension cord across the
street to power our saw to cut the forming lumber.
We were fortunate to have extended family willing to help on
the project. My two sisters and their husbands (and families) came from
northern California ,
and I had two brothers in town and their families who also helped us get ready
for placing the concrete in the forms.
After the forms were in place and the trenches were cleaned out, we put
down two inches of "clean washed sand", covered with a sheet of Visqueen
plastic as a moisture barrier, which was covered by two more inches of sand.
With the sand in place, we began tying the rebar. There were two pieces of 1/2" rebar in
the bottom and two at the top of all the trenches. Then we placed 1/2" rebar every 24"
across the slab, in both directions, supported on "dobies" so that it
would be in the center of the concrete slab.
Once the forms were in place and the rebar tied, we called for
the form inspection, which we passed without any problems.
The next big hurdle came the day we placed the concrete. Fortunately my brother, Don, had some
experience placing and finishing concrete, and I had worked with him on the
driveway in Inglewood . So we took on doing the finishing
ourselves. Truckload after truckload of
concrete were emptied as we filled the footings and then the slab. We were fortunate that all the areas needing
concrete could be accessed using the truck's chute. This saved us a lot of money that it could
have cost had we needed to have the concrete pumped.
There was always the
concern of "cold joints" as we experienced time between trucks. After the next to the last truck was
unloaded, we had to hurry and calculate how much more concrete was needed to
complete the job, and the truck driver radioed dispatch to let them know how
much to send in the final truck. In an
attempt to minimize the cold joint problem, the edge of the concrete was raked
thin, and the new concrete was worked into the edge to help them join together.
Foundation bolts ("J-bolts") were placed in the
appropriate locations while the concrete was still fresh. After the final truckload was emptied, the
driver washed out his chutes and was on his way. Of course we had to screed the concrete to
the correct thickness as the slab was placed.
And someone tamped it to work the larger rock down below the
surface. Then we ran a float across the
surface to help smooth it and bring more slurry to the surface so it would
trowel easier. The fresh concrete needed
just the right amount of time to begin setting up before we could begin
finishing it. Working it too much, too
early, just extended the setup time, before it could be troweled. Waiting too long, it becomes too hard to
trowel properly.
When it was firm enough to walk on, I helped Don place the
power trowel (a gas powered machine that resembles an over-sized buffing
machine with several trowel shaped feet on it).
This allowed him to finish the expansive area of the slab fairly
quickly. Once he was done, we still went
out on knee boards and hand finished the concrete floor.
It was a long day, and we were beat by the time we were able
to go home!
