    We are working on this now. What exactly are your questions about the process?

    Please tell me the entire bottom of each blue stone peice has mortar contact. It almost looks like you just put a trowel of mortar in each corner.

    I guess I was just curious about the normal layout/procedures. Think I have a good idea of how the process works. Was also curious for those of you who have done a few of these, if there is any handy tricks/tips to watch out for or to make things go alot smoother. Thanks for the pic. Keep 'em coming if you got 'em, like to put pics with words.

    I can see how you would make that assumption by that piece in the bottom center where the mortar oozed out. There is about 95% coverage, there is some space under there just let the stone set.

    I also have a few questions about the topic. My assumptions are this.
    1) form and pour a slab at least four inches thick, over 3/4 clean stone.
    2) Level the slab, but leave the surface a little rough.
    3) Lat out stone on a mortar bed, leveling each piece as you go.

    Questions:

    1) How long must the slab cure before the overlay?
    2) Do you need to cut and control joints (don,t think so because the overlay would crack with them)
    3) What type of mortar is used to bed the overlay?
    4) Is the same mortar used to finish the joints?
    5) What is the best method for filling the joints? (trowel, Bag etc)
    6) Can you just wash the excess mortar off of the stone as you are filling joints?

    May seem like some basic questions, but I don't believe in learning on a customers dime. I wan;t to try one for myself to make sure \i have it down.

    1) form and pour a slab at least four inches thick, over 3/4 clean stone.
    yes, and use wire mesh re-inforcement in the concrete

    2) Level the slab, but leave the surface a little rough.
    yes

    3) Lat out stone on a mortar bed, leveling each piece as you go.
    yes, string lines etc.

    Questions:

    1) How long must the slab cure before the overlay?
    let cure 1 day give or take until hard enough you can walk and work on it.

    2) Do you need to cut and control joints (don,t think so because the overlay would crack with them)
    cut the pieces of stone as needed if lines are not straight

    3) What type of mortar is used to bed the overlay?
    type N or M will work

    4) Is the same mortar used to finish the joints?
    yes you can use the same, or if you want a white grout then use white mortar etc.
    5) What is the best method for filling the joints? (trowel, Bag etc)
    trowel seems to work best for us

    6) Can you just wash the excess mortar off of the stone as you are filling joints?
    yes was immed. with sponge as you go, keep everything clean.

    Another step worth mentioning is to clean the stones. Natural stone tends to be a little dirty from the quarrying/cutting process. You want to make sure you have a good bond between the stone and mortar. Some water and a scrub brush does the trick.

    While we are on the topic, did anyone see my thread about the water feature?

    In the case of a formal water feature that is either in the ground or has a raised section, how do you go about the construction?

    I imagine that you would pour a slab, then the walls. The walls would then get a stone veneer and cap.

    1) How thick should the concrete be, and do you leave re-bar sticking out of the base to anchor the walls with?

    2) In terms of the finish, I see many that are painted inside. Is this done right onto the concrete, of is some other finish applied?
