First Pour: The first four inch layer of concrete is poured
into the mold. Typically we use an add-mixture commonly known as
Self-Compacting Concrete (SCC) to allow for a smooth surface. This
layer (or wyth) is the structural layer and is reinforced with rebar
and mesh.
Insulation: For insulated panels, the next step is to install
the insulation. We use DOW’s Styrofoam Brand Insulation (Blue
Board), which is closed celled and typically two inches thick. It
is laid onto the wet four inch layer of concrete, and patented composite
connectors are inserted every sixteen inches on center. These are
the "toothpicks" that hold the "sandwich" together.
Second Pour: The two inch top layer is then poured and given
a smooth trowel finish. The panels cure overnight in the forms where
they will typically reach a strength of 7,000 to 9,000 psi. The steel
casting beds are then tilted vertically, and the panels are stripped
from the forms using an overhead crane.
Finishing: The panels are taken to a finishing area where
they are checked, marked, and cleaned before going to storage.
Trucking: The panels are stored vertically in racks until
they are ready to be shipped. When the job is ready, they are loaded
vertically onto drop deck trailers and hauled to the site.
Erecting: Once at the jobsite, they are picked off the trucks
and installed by our experienced crew.
