Whop Whop!!!! LOL all done! The foundation looking really great. They really going to tight the cables after they pour the 2nd pour? I really don't understand that process.

Concrete takes several days to "cure" (settle, dry out, and come to its stable strength); and the post-tension cables are in the slab to add strength and compression to the slab (concrete is stronger when compressed).

So they wait for the concrete to cure a little before tightening the cables so that the cables actually add to the tension in the slab and make it stronger. If they pulled the cables before pouring, it wouldn't affect the tension in the slab (the concrete would just cure and settle around the tense cables), and wouldn't add to the strength.

I actually think this is why they're called "post" tension cables -- as opposed to just "tension" or "pre" tension cables. Because the tension is added after the concrete has cured some.

@somaria: VERY cool :D I can't wait for frame to start going up!

Aha now I understand it. Of course there is no such thing in Toco House!

Now it is time to set up your chair by the house and watch how fast the walls goes up!

Yeah, I'm excited...I think I'll start taking video when framing and stuff starts going up :)

Seeing the foundation really made me realize we're building something that's going to last for decades! Made it seem more real somehow.
