I plan on building a basement so I will have 2 lifts. I've read I can start stacking the blocks for my next lift in a few days after pouring the first, but how long should I wait before pouring my 2nd lift?
I'm assuming once the concrete is hard at the spot of the cold joint.
Thanks,
Chad Newman

Chad, my feeling is that you can start right
away with setting the next course's. You will want to wait a day or so before moving
the braces though. The sooner the new pour
meets the old pour-the better. Hope that helps. Unless you have a 20'basement height,
then wait 2 to 3 days before moving upward. |

Chad: Am I missing something here....you plan on building a basement right? You can stack the entire basement up say to 10' then place concrete all at one time...in two lifts is that the real question or do you intend to form up 4-5' then place concrete then form up 4-5' again and place concrete? Most of our two story projects are built with the floor system installed start to finish in less than two weeks. You can pour an entire basement in one day, the next day you can set the floor system, then deck it and on the third day after pouring the basement you can stack the upper floor...take two days or so and then pour the entire upper floor...

Chad, I think you are asking about pouring 4-5 feet of wall height at a time, and Assuming this, not using scaffolding???

Sorry folks, I didn't mean to cause any confusion.
My end goal was to find out a wait time in between lifts to prevent some problem if there was one.
I've concluded from what everyone has told me in this thread of conversation that this is none.
I'll be using eco-block and use the bracing/scaffold system my local distributor has.
As Ian has said, in order to do this I'll have to get my first lift (basement) done with the ledger in place. Set up the joist and decking so that I can move onto my second lift (the remainder of the house).
My first lift will be at 10' feet and my next lift will be at 9'4".
Once again thanks and sorry about the confusion.
Chad Newman

Be careful of the "ledger in place"? This to me says you are installing the ledger, then pouring. Although some blocks have a compression or settling when poured, depending on which attachment system you are using you very well may wind up installing the ledger after the pour. On the last project, we used Simpson ledger hangars, and we installed the ledger and joists off the staging, because we could remove the 3' extension at the top of the staging and work without ladders.

I set the ledger in place before pouring on my basement, but I will never do it again. As mentioned above, settling occured and the ledger was not level. I had to snap a line and rip cut the ledger in the high spots. Next time I will set just the bolts and attach the ledger afterward.

Okay, time for the quick plug.
SSSSPPPPEEEEEEEEEDDDDDDFFFFFFFLLLLLOOOOOOOOOOOORRRRR!!
is exactly what it is. Two guys, One day to install 2500 square feet, no ledgers, no forming, no shoring, cut to length, set in place, put in lock bars, lay in plywood, lay down mesh, then pour the entire floor level with a lazer. Installed at the cost of TJI's
If you are off a bit, it does not matter, it can be leveled with the floor, bu up to one and one half inches.
The best is, you cut to suit the job, like a floor joist. Its easy, its fast, its low cost. Its simple.
I dont often put in a plug for our company, but this one is a good one. It works and works well, and all you need are simple span charts. You cant even order the wrong size, because it is shipped in max span lengths. A 24x32 building requires just 7 joists. And any concrete finisher can pour the floor, even with wheel barrows. In one day, you have a floor, which is quieter, stronger, wont rot or support mould or mildew, 2 hour fire resistant, and capable of parking your car, bus or truck on. And clear span too.
This is my shameless plug. But I just hate to see, people installing wood with concrete wall systems. I believe that concrete, should go with concrete. Matching materials definatly co-exist quite well together, and no more rotting toilet areas or under tubs.
