What the heck is Coble Stone?

Can any one show me a picture of some Coble Stone?

While I've got your attention, How about some pictures of walk ways?

And How about some bridges and pod patios?

OK Thanks.

So to lay it, you just get a good solid base, the fill the gap with sand?

This is new to me. We are working on a pond that will probably reach the $20K point, and she keep's asking for more.

Leave the sand on top and use the compactor to vibrate the sand all the way down. Once down you can drive a 10 ton truck over it and it won't move.

Our procedure is to sweep sand in..clean it off ..tamp and sweep sand in again. If you leave the sand on while you compact you may get thicker spots of sand that could cause a uneven finished product.

Kris,
I don't know what you mean??? The stones should already be down and tight, so what do you mean "thicker spots"?? If the stones move, something is wrong. I've seen jobs with the sand just swept in and they don't last as well as using the vibrator machine. Did I use the wrong word by saying compactor???
Thanks,
DP

No your use of that word is fine ... I don't think I explained myself very well .... The stone is done, yes its tight. you sweep it in with sand then tamp (compact) ...this is the part I think your not getting> you shouldn't leave the sand on top as you tamp...the surface should be fairly clean if you have a thicker amount of sand on top of the stone then other parts it could cause it to tamp the stone down just slightly further. Understand?

It's just a small detail ...if your base is good it may not make a difference.

on edit: lay stone
sweep in sand
tamp
sweep in sand

I think we both assumed that, however, "I" did say that, which I should have. Sure, if the compactor leveled things, a 1/16 inch of sand on top would lower that stone a bit............
