    To block or not

    I am going to be putting up a 27' round once I have my site level and the install plan shows to use a 2"x8"x16" block below each bottom plate on the 18 wall uprights of the pool. In talking with others that have had their pool professionally installed as recently as last week, their installer didn't use them because as the block tips on the ground so will the wall upright.
    Have you had a block issue on your pool? How many years with the block in place?
    If you didn't use block have you had issues?
    Should I block it or not? I already have the block so it is not a money thing.

    I would block it. We used blocks on my previous above ground that my dad put up and I used the same blocks with this above ground that I put up.

    My blocks do not and have not tipped once. If they would tip, it's because it wasn't properly leveled in my opinion i.e. dead space and compaction over time.

    from what I've read it's a matter of preference...but I would follow what's in your pool warranty/instruction manual so you don;t mess up the warranty. There really isn;t that much downward force on round pool uprights...the pressure is more outward than downward..the downward pressure is under your liner

    BAH!

    Of course you 'block' it Anyone who had the blocks shift didn't compact or properly prepare the ground first

    Re: To block or not

    So do I set the block on top of the level ground or sink them flush?

    Top
    get the ground level
    set the blocks on my track line
    put my sand down
    compact it
    then put up the track on the track line and blocks

    or

    Flush
    get the ground level
    dig out the block spots and set them flush with the ground
    put up the track

    flush...dump the sand in the center of your pool...then the sand gets spread out and compacted after wall is up...this will prevent sand blowout
