LiteDeck

So after a discussion with my builder about the *currently* limited availability of the steel trusses we were going to use for the floors, we've decided to use an ICF floor system called LiteDeck.

Specifically, we'll be using the WRS or wood rib system.  LiteDeck produces two systems, one with an integrated metal "C" rib insert, and one in which you provide the 2x6 to be used as bracing for setting up the floor.

 Some of the stacks of the LiteDeck.

 Here you can see how they will mesh together.  The narrow slots are for the 2x6 that will be used to provide bracing before the concrete is poured.  The 2x6s can be removed after the concrete is set, or kept in place.  We'll be keeping them in place to act as nailers for the ceiling underneath.

The 6" deep channel will hold 2 thick pieces of rebar that run the length of the install.  These are held off the bottom of the channel by small plastic spacers.  A rebar grid is laid on top of the decking after it's all installed and concrete is poured into all the channels and up to the thickness of the floor.  When cured, the channels act as concrete beams, supporting the weigh of the floor.  My father in law couldn't comprehend where the strength of the floor is derived from so I told him to look at a parking garage and show me where the steel I-beams are.

 More LiteDeck stacked on the side of the house.
