How to Put it Together
f you are looking for a superior and professional job with
concrete placement and finishing I suggest you go to the pros. The old saying
is ‘you can’t beat a tradesman at his work’. The photo on the left shows the float
work after the 3500 psi concrete has partially set. Approximately (12) hours after placement its durable enough
that you can get onto it and begin the final finishing process. The concrete was covered to retain moisture
in the mix during the curing process. This visqueen was saved and later used on
the end of the existing structure as shown below. Notice the 3” sewer vents and
the corner tub drain. This is a
concrete float the contractor is using to refine and smooth the surface of the
slab. The end result is a wonderful smooth floor surface suitable for a shop,
laundry, and sewing center.
Other aspects of importance are the exterior wall anchor bolts.
All of this must be carefully measured and placed according to the wall
orientation in the engineered plan.

to these photos.
Even with careful planning I still had to place more anchor bolts
after erecting the walls. This was done using a ½”rotary concrete impact drill
and boring into the curing concrete -through and under the wall sills- (24)
locations. Once this was completed the holes were sucked free of concrete and
wood particulate. I used structural grade epoxy resin, injecting the mix into
the holes. Next I placed ½ inch all thread studs into the holes. The set took
about 24 hours to cure. These additional anchor bolts insure the walls do not
leave the slab during high Kansas winds.
The resin installed bolts actually have a greater hold strength than the
bolts placed in the slab during placement.
On the left you will observe the open end of the existing post and
beam building. It is covered with 6 mil. plastic sheeting to keep out particulate from
our living quarters during construction. The extension slab and the sidewalks
are now completed and ready for the next step.
