Cinder block chain wall
#1

I already have a one foot concrete chain wall in my back yard which was supposed to prevent my neighbors yard from draining into my yard when it rains.
Well, it still drains into my back yard.
What I have in mind is to add 8 inch high cinder blocks on top of the concrete chain wall. But what I need to know is:
Do I just put martar mix on top of the concrete chain wall and lay the cinder block on top or do I have to anchor the cinder blocks to the chain wall with Rebar or mesh??. Also, will I have to fill the 2 big holes in the cinder block with martar or rocks or something to stablelize them??
I am only going one cinder block high and will put a wood picket fence on top of them.
DUUHHH?

But just to inform you, it is a solid piece of concrete, 8 inches wide and 12 inches high, that goes completely around my back yard. I had to make a form and pour the concrete in the form, $600 worth of concrete.
What I intend to do is go up 8 more inches using the cinder blocks.
All I need to know is what should I use to fill up the cinder blocks??
Iam thinking of using gravel instead of concrete. If I use concrete Iam looking at another $600 .

Chain Wall - What you are descibing sounds like a retaining wall.
Yes you can cement the blocks on top and fill with gravel, I would put a cap block on it to make it look finished

I try to avoid colloquialisms here. The term concrete chain wall is not specific, except to you. The term poured, concrete retaining wall is a tad more descriptive. I agree with frank99's recommendation.

Yes, construction descriptions and technics can vary from region to region. I have never heard of a "Chain wall" either. It almost sounds like some kind of curb maybe? Or is it actually as was mentioned retaining earth?

Chain Wall


Seriously, a guy that does concrete prep (forming, form boards) told me a chain wall was a concrete foundation under a house that involves a poured concrete footer under the perimeter of the house with a footer running down the center. A chainwall foundation on a shotgun house would look like this:
_______
|_______|
|_______|
The house is then raised with cinder blocks placed every 6 feet to the desired height. It seems to be an upgrade from the concrete piers under the floor joists that settle and sink over time which 'unlevels' the house on a pier and beam foundation.
