How to pour wall extension??

How to pour wall extension??

How to pour wall extension??

(OP)
At work we are designing a wall extension.  The wall will extend into a door way about 18".  We want the entire surface of the extension to be flush (square).

The extension will have forms on three sides and an existing wall on the other side.  The top and bottom of the wall will be the ceiling and the floor.

We're trying to figure out how to pour this wall??  We obviously can't just "pour" the wall since it will be enclosed by forms.  

I'm sure this is a minor problem for many of you but we just have not dealt with this situation before.  All comments appreciated!!

RE: How to pour wall extension??

The options you have are:-

1.  Pour as much as is physically possible and then use a dry pack or epoxy mortar to fill in the final part up to the ceiling once you have stuck the formwork.

2.  Make a hole in the ceiling above just off line of the wall and use a letterbox or birds mouth shutter.

3.  Pump the concrete in under pressure with a riser pipe at the top of the wall to let the air out.  When concrete appears here then stop the pump.

I recommend option 1 as the simplest and cheapest.

Thanks!!  I'll look into those.

RE: How to pour wall extension??

What about using CMU instead of concrete?

The wall does see significant lateral loading so it's not a "simple" wall.  I suppose it's possible but I'm MUCH more comfortable with concrete design.

Does the lateral loading affect the methods of construction listed above (sorry I should have posted about the lateral loading originally)??
