Hey Rob (or Cheryl),

Thanks for the note... I did remove the tile and now I need to "really"
seal the cement block. You mentioned Drylok?... I'm thinking of using
some kind of paint product that when applied will create a rubber
barrier on top of which I can replace (sigh) the tiles. Will drylok
create the rubber barrier that I'm looking for?

Thanks!

Wayne

What kind of blocks are they?? Hollywood blocks?? Solid blocks??

I am almost sure they make some sort of grout sealer; but I am skeptical as
well due to the fact that some of the tiles are constantly submerged and any
chemicals or what have you would break the barrier down sooner of later.
Another option would be to take all the tile back off and just use some
Drylok on it and then put a scratch coat of mud down and re set the tiles. I
know it sounds like a PITA and it is. Sorry I can't be of more help; I wish
I could. Hopefully someone else will chime in and give you more ideas.

I built a pond (fountain) that has a concrete base with concrete blocks
around the edge to create the pond. Despite that I treated the block
with some water sealer I get seepage to the exterior of the blocks. Is
there any type of water treatment that I can add to the water that will
stop the leagage. The inside of the fountain is tiled so the treatment
must enter via that grouted area.

Thanks,
