Construction continues . . .

So on June 2, we completed the pour of the basement floor, but the guy hired for this said he would come back in two days to seal and cut the expansion joints.  Later I learned the typical procedure is to seal it the same day it is poured, so I wound up doing my own sealing of the concrete the next day and hired someone else to cut the joints into the work.

While the pour went pretty smoothly, the finish was incomplete as is evident from the difference in color after the sealant went on.  Note the rough edge around the pipes and walls, that was not done well, but most of this will be covered by the floor covering of tile or carpet, and it will not matter for structural issues like strength or durability.

For the cost of framing the walls, and the small amount of interior wall we have, I decided David, Ben and I could do it without too much trouble.  The next week we spent putting in some of the basement walls and “shoring” for the deck which would be the garage floor.  This was designated by the engineer we hired to “design” the LiteDeck floor we are using for the garage.

IMG_3501LiteDeck (http://liteform.com/litedeck-srs/) is a product of styrofoam, steel studs, rebar and concrete that is easily installed.  The two of us were able to easily lift the decking into place, precision of preparation of the walls being the key!  We were not out by more than an inch in any direction so the deck fit in very nicely without any trimming.  This was accomplished in just a couple of hours on June 15th, but we had to wait a couple days for the rebar that we ordered which had to go in the “valleys.”  So on the 17th we were able to pick up the #7 rebar and put it in the valleys of the LiteDeck.  The number on the rebar refers to how many 1/8ths of an inch in diameter it is measured; i.e. #4 rebar is 4/8 of an inch or 1/2 (1.25cm), and #7 is 7/8 of an inch (2.3cm), so almost a full inch in diameter.

After laying the hats in place, we added a wire mesh and #5 rebar which was linked to the #7 rebar by the engineer’s design. To lift the mesh and #5s off the styrofoam we ran several #4 rebars crosswise to the beams of the pour.  So now we are ready for the concrete to go in.
