Gomez + Sons Concrete accommodated our schedule by doing their work on Saturday. It would have been difficult for the framers to do their work around wet concrete. We hired another company with a concrete pumper and boom to reach over the site and pour the back patios. They sent, instead, an antique piece of equipment that kept breaking down. As a result, Jose Gomez and his crew had to wait around while they fixed the pumper. The concrete trucks were lined up waiting to dump their loads. It was a bit of a fiasco, but in the end it was all done well; thanks to the skill of Jose and his crew.
The concrete pumping tube wasn't cleaned out well after its last use and was full of dried concrete which had to be pounded out with a sledge hammer (left). Once that was fixed, they began to pour the east slab (right). You can see the wire mesh which strengthens the concrete. The wooden forms are put in place temporarily to contain the concrete while it cures. We're leaving the forms on longer to prevent workmen inadvertently chipping the edges as they drag lumber and cords into the house.
The pumper hose was then dragged to the workshop/garage. The concrete is covering the tubing for the infloor radiant heat. Later, we'll run the same tubing on the wood floor in the house and pour a lightweight concrete over it. Once the concrete cures for a while, they ran a motorized float (above right) over the surfaces to smooth it out.
The final step is to hand trowel the surface. We chose a smooth finish, but added a subtle brushed finish (done with a regular broom) for traction. We covered the concrete with plastic for the night to reduce evaporation. Concrete cures stronger and better with water. We will hose off the slabs over the next several days to give it the water it needs. This helps prevent cracking and makes a stronger finished product.
Of course, we all had to sign our names in the concrete! Even Jack and Willie (our dogs) did their part. Our friends came by and added their names. This was the day of the Columbia catastrophe so the concrete pour was laced with shock and sadness.
