send a little this way:wink:

I'm not as concerned about movement as I am with freeze/thaw. There's also a chance of bulk water being trapped and possible hydraulic pressure, however slight it may be. Damp veneer = algae growth. Keeping it dry on the inside means quicker drying cycle on the outside.

got it:thumbsup:,
it's just i thought a grouted angled stone sill applied to a concrete foundation would be able to do this independently of any metal or sealant

but no mason am I:no:

ok ok i'm not a hydraulics expert

Could the OP leave a 1" gap between the stone veneer and the concrete wall?

Wouldn't the concrete wall be (already below grade) waterproofed first?

Wouldn't the flashing metal tuck under the WRB behind the vinyl and (or under the mudsill) extend a little onto the sloped (pitched) stone to run the water from above that point out at the top the stone?

Why need sealant at the top inside of pitched stone if the whole veneer is open air space behind. Solar drive would drain in the air space, and out below.

There wouldn't be any hydraulic pressure if built with an air space and the concrete wall wouldn't get wet to diffuse water inside. You don't want/need a poly vapor barrier below grade. You wouldn't need a WRB behind the stone. You wouldn't get freeze-thaw with an air-space. If in a high moisture area and wanted extra protection, just set the veneer off with a mat; read "Conclusions" pp.9: http://www.buildingscience.com/docu...-work/files/RR-1010_Innovative_Passive_Ventilation_Water_Resistive_Barriers.pdf

A good read for stucco/stone with OSB or plywood: http://www.buildingscience.com/documents/insights/bsi-029-stucco-woes-the-perfect-storm

Hope this gives you some ideas (food for thought).

Gary,

The 1" airspace is good for a real stone veneer, but the OP is looking to install cultured stone. He could obviously create a rainscreen system behind it, but it would be a ton of work for minimal benefit.

see,turned out to be a fun informative discussion:thumbup:

It's been a while since I started this project but I finally got it done and used most of ya'll advice. I bought a roll of trim coil, rented a brake and bent some flashing and the installed it under the siding and behind the weather barrier. I than used a water table stone under it with a built in drip edge. The extra cost was about $1000 compared to not having anything to divert the water. Well worth it for peace of mind. Adhering the stone wasn't to bad, time consuming as all get out but well worth what I saved doing it myself and I couldn't be happier with the results. Here's some pics, thanks for all the help
