That makes me worry. I told them I will be the only one.
Is that a problem? Will I be able to handle it myself?
Either they are you are going to be in for a big surprise, hopefully it will be them!

You don't have to have one but it would certainly make the concrete flow smoother into the form and reduce the possibility of voids. It will also probably give you a better finish of the concrete against the forms.

Ok guys,
This is what I got!

I calculated 4.53 cubic yards and ordered slightly more (5 cubic yards). When the truck finished pour I ended up slightly short and had to rent a Mixer and buy another 16 bags (5000) from local Home Depot.

After all form stood well on both LOWER...




...and HIGHER sides




The only issue is that, because I was working alone (well not exactly - my wife helped me) I missed couple of spots and did not finished it properly on top.

For this purpose I got Hydraulic Water-Stop Cement by Quikrete AND need your input on this:


Another question is when I can start removing wood?

Ok, guys,

My agenda slightly changed since I am NOT planning to put Chain Link Fence on top of this Concrete Wall that I just poured. Instead I want to go with Concrete Block Wall. Thanks to the guy from Building Dept who gave me this idea. Then most likely I am going to finish it with Stucco or something.

When I poured concrete I did not really finish it on top and its NOT really leveled. So now I want to finish it with Hydraulic Water-Stop Cement (Quikrete) to make it more leveled before laying out Blocks.

That's why I did not remove the wood yet...

Is this stuff Ok to do it?
Do I have to prepare (finish, level, etc) it this way?
Or I will be Ok starting with Blocks just like that?
Just make sure that first row gonna be leveled?

Thank you in advance,
almazon

If you are going to just put block on top of it there's no need and leveling at 1st. You can just pulling string line for the top of the 1st course and level the blocks with the mortar bed. If fewer types of material that are involved the better.

You're changing the entire scope of the project now. Before, it was a light fence, now it's a block wall it's supporting? Now, with the change, and your environment, as well as it's location next to a sidewalk, I'd highly suggest you don't build a block wall on top of that with out frost protection...........

Anyway, guys,

I removed the wood and this is what I got so far. I think its not THAT bad:




I decided to keep existing Chain Link gates for now:






Need some finish in couple corners:




I think it will be enough support for Block Wall considering it goes in average 3' deep.
I am planning to use 6" Blocks (Wall itself is 8") and flush it with Inner wall giving some space for finishing on Outside.

This is what I am talking about when I say its not really leveled:


Do you think I will be able to fix (bring to level) it at 1st course of Blocks with the Mortar Bed?

Thank you in advance,

That should be very simple to correct on the 1st course of block!

I realize you've likely already made your mind up, and there's no way to change it, but I still think this is a bad idea. Sure, you have a few feet of wall in the ground, but is it set on a spread footing, meaning a footing that's about 8" thick and twice the width of the wall? Is the below grade portion of the wall formed smooth on both sides to deter frost "picking" against the wall? Is the wall isolated from the flatwork surrounding it with proper material? Unfortunately, I believe the answer to every one of these questions is "NO", and what you're trying to do goes against all "best practices" in the construction of a foundation and wall in a frost zone............

What's the worst that could happen?

Worst case? The wall will start to lean---

I'm not a mason by anyone's estimation---so take this with that in mind.

Could you build a short block wall and then extend the height wiith a light er privasy screen?

If that were mine I would be checking with my insurance people to see what their specs are. It would be bad to go ahead and build a wall that they will not insure, then have to take it down.
