    Not a pro in this area of the feild but was looking into the construction process for a waterfall and the one I was looking at called for some sort of sealer between the rock that the water runs over and down. How do you correctly install this and and what type of sealer do you use?

    you need waterfall foam. It's basically "Great Stuff" that is black/grey so it blends better with most stones. Apply liberally, wait a minute for it to fluff up and then place the stone back down into it. Don't get it on your hands!

    so is it like glue to hold the rock in place, in that case do you cover the entire area the rock covers with the foam or is it a sealer, which you could just basically place is where the rocks meet. Basically what is it used for.

    its primarily a sealer. Most guys apply it on the uphill side and like to see it ooze out a little, this way they know they have a good seal. Wait for it to dry and then you can cut it off with a utility knife or cover with small river stone. If you do cut it, make sure you don't cut the liner.

    Another trick you can use to hide the foam is to sprinkle small amounts of rock dust over the un cured foam areas, works great!
