Applying flagstone to cinder blocks
 
I am building an above ground pond, I bought flagstone hoping to place it on the wall of the pond to make it look more natural. I am trying to find a good material to use to get the flagstone to stick to the wall, all the larger pieces will be flush with the ground so what I use doesn't need to support a large amount of weight. I have heard an idea on thin-set, stuff for laying granite and marble, but I wanted to get some more opinions. I am new to most of this stuff, but if someone could point me in the right direction, it would be greatly appreciated.

thanks!

You say "flagstone" but we need to know if is man-made for veneering or actual/natural flagstone. Veneer stone would be lighter and easier to apply. Also, what kind of surface is the pond?

It is natural flag stone, and most of the pieces are 1 1/2 inches thick, as far as the surface of the pond, it has a small small concrete layer with cinder blocks going around it as a wall, this wont be an in ground pond. the cinder blocks have mortar on them to connect them to each other. I have gotten this far but am not sure what would be the best way to finish it. I just need to put the liner in and attach the flag stone to the cinder block wall, it is only one cinder block in height.

fit the flag onto the exposed part of the conc base & slap 'em on w/mortar,,, just be certain the block's CLEAN 1st.

I am curious as to how you are going to water proof the walls. Are you going to use a liner or try and seal the block somehow?

maybe i miss'd something,,, ' just need to put the liner in and attach the flag '

poet2dager 08-17-2010 07:10 AM

yes, I am using a pond liner, cinder blocks are just to add support and some height so the water won't be too shallow and heat up the pond during our hot afternoons.

Itsreallyconc: my first plan was to clean the blocks get some mortar and like you said, slap them on after fitting them, but I wasn't sure if the mortar would be sticky enough to hold up the blocks until it dries.

if i'm reading your op correctly, there's a bit of the conc footer showing,,, the mortar will hold the vertical pcs of flag but not suspend them as it would act if you were to face a home for instance.

we'd use a mortar bag to fill the jnts 'tween the flag then ' tool ' the jnt as you would w/any brick/stone/mortar work.

I am probably at the lowest level of knowledge about masonry, would you mind explaining what ( 'tool' the joint) means? or maybe direct me to a website that could help?

itsreallyconc 08-17-2010 10:11 AM

hie thyself over to an apro0n store & buy a book on stone/brick work,,, you should see a picture & description of joint ' tooling ',,, probably easier finding it there than the library.
