my sylvan built pool never had this gap filled. i just learned of it's importance. there is a foam cell insert that has dropped deeply into the gap, and of course is now covered with twigs and leaves and dirt.
the depth of this gap seems to be 3-4 inches deep, once i pull out the old dirty foam stuff that was inserted.
i have read about caulking the gap and other items that are used to seal the gap.
my question is: what do i put into the gap to fill the bulk majority of the depth of this gap?
it seems that backer rod would not fill the depth enough. do i use sand? do i pack sand down then apply caulk/sealant?
i'm just so perplexed due to the depth of this gap between the coping and the pool decking/concrete.
thank you in advance
