DIY,

We have done these in the past and you are right that the insulated edge is a concern. What we have done is put a strong back all along the outer edge and brace that with kickers all the way around.

DIY,

The floor system and the ICF bracing is more that sufficient for the walls. Keep in mind that you also have to shore thet floor system.

I have poured a monolithic wall And lite deck system in Virginia back in 2003. I was using fold-Form system and we used 3/4" cleats around the perimiter of the foundation to give the outside edge support during the pour.

This situation is only for the ICF professional! A DIY skill level will be challenged enough with the wall pour much less trying to pour the Lite Deck along with the walls and not knowing how much comprssion to allow and how many workers are needed.

If you choose to do seperately there are better ways to do the pour than the method described. Repost as to what help you will have from your ICF dist. and what skill level of help you will have.

Dave,

You are correct that this is not a do it yourself project. I have been keeping some late nights and early mornings and did not think what DIY stands for. Although this is not an extremely technical thing to do. Dave is right that you need a lot of experienced people there to get this poured out. You need people that are experienced at pouring ICF walls and people who are expeienced at pouring finished slabs. If you are going to color the slab then this throws a new wrinkle in. There are so many issues that a concrete professional has to look at to determine how to pour out a project like WEATHER, wind, temp, humidity, sun exposure, MIX TYPE, will it change during the pour, retardant, hot mix or not, distance the trucks have to travel, mix design, engineering specs on the mix.... There are many many things an experienced concrete contractor does and thinks about before a pour that the average and even above average DIYer has no clue about.

Make sure you have plenty of help and tech support from your block rep.

Thanks for the info. Just a little backgroung on myself I have owned my own concrete company for over two years. We specialized in box culverts, which is nothing more than a cheaper bridging structure. We have done some of our top deck pours monolithic with the walls and some we have not. All my forms were hand made from plywood using a whalers and strongbacks. This would be my first attempt at using ICFs. So I am just trying to get some feedback on monolithic pours with the walls.

I figure the best way to go about it would be a scaffold system to support the lite deck while it is being poured. This system would be on screw jacks that would allow for any changes due to compression of the forms themselves. I plan on having the basement SOG poured so that I don't have to worry about compression of the scaffolding system into the soil. I guess I could do the walls and the deck as two pours but I was going to try and save a little money on concrete pump costs.

Greatly appreciate any feedback.

The only thing you may save is travel time, depending on the size of the job you may not even save that. If the guys are tired the deck pour will be slower after the walls, eating up any savings.

we have done LOGIX ICF/concrete floors and decks throughout a three story project. we did it different for different floors becuase of using diferent contractors. our pictures and details tell the story:

good luck!

We've done small projects including walls, floor and parapet all the same day pouring with 2% calcium. I know i know calcium isn't recommended, but the owner signed off on it...

Chris is right, it doesn't save much time, and for safety quality finished product and ease/enjoyment of installation breaking up the pours is smart.
As an option we have poured the walls in the am, cleanup regroup and pour the slab above in the afternoon, but the pump will have to clean out, spend all day and it will cost the same anyways overall....

If you use a fixed form and space your floor eleveation to allow one half of the web to maintain integrity the cold joint pour area is stronger, also bracing from the outside is a great idea if you are able.

Don't pour the walls before double checking your rebar connections/layout for the floor above!
