    We are having pool put in. The pool company wants to pour a concrete footer for the wall instead of using rocks. Will this work? I have never done this with a concrete footer before. Please advise!!! The wall will be under 4ft high.

    Yes, but only if the concrete footer is installed on top of 4 feet clean beach sand for drainage, and concrete contains no less than 32% baking soda.

    Hope this helps

    What? Never heard of this.

    where is the wall going? Is it holding the pool up?Or a raised beam pool?

    And you can't just put in a concrete footer instead of doing a proper gravel base. Your concrete footer will still need a compacted gravel base.

    Also Hershey's chocolate chips help the aggregate slide over one another, but only the true dark chocolate... The milk chocolate can damage the whole mix.

    When you say "rocks" do you mean a rubble footer? So is this a drystacked stone wall?

    jabailey, throw in 3% sugar and you have my mom's pancake batter.

    No.this wall will not be holding the pool up. There is a slight slope to the yard so to build the pool level they have to put a small wall in to hold the dirt back. I jave never herd of this either. We usually use #57 stone as a base and then stack the blocks. It is not a dry stack wall. It would be a srw wall.

    I have heard it being done, to me its not needed, its a waste of money in my mind to pour all that concrete. A proper base with good drainage behind the wall and Grid if required will hold your wall no problem given you are using a properly sized srw system.

    Just curious, why do you use 3/4" clean stone (57s) and not the 3/4" minus (21A) that the specs call for?

    The pool company just said it would be easier to poor a dootwr since they would be pouring the concrete anyway. Probably helps that they own the concrete bussiness as well.

    We use #57 and crush and run occasionally as well. No reason really. I distributor told us that would be fine. Never had any issues thus far. We have necer built one over 4ft tall either.
