View Full Version : Marble slab install

I am getting ready to install 24”x36”x3/4 marble on concrete.. We are most likely going to do a fresh, wet set. My issue is the slab has a few cracks in it. Im thinking to hydroban the concrete and set on top of that. I realize that a typical detail would be mud to bond to concrete but if I do that there’s no barrier between the cracks. How does everyone feel about CRack ISO membrane and wet set on that?

Many thanks!

Hi Paul, :)

What do you mean by "wet set?" What type of cracks? Pictures help. :)
