Stone facing attachment on ICF wall
What is the best way to affix natural stone to an ICF wall? We have designed a walk-out basement home with ICF on the lower level and are planning to to use granite ruble stone from the property to face the walls over the above grade ICF portion. The detail drawings from this site show an air space behind the facing, but that detail was for a stick wall. If we were to use an air void behind the wall how would we anchor it given the significant weight and irregular shape of the stones?

Dean,
以下是与两个品牌的ICF砌体锚点的链接:

谢谢你的联系马丁。那么,你正在推荐石头背后的空气空间,对吗?但帮助我了解...如果与ICF墙直接联系到等级以下,为什么直接接触石头面向不起作用?直接粘贴石头的缺点是什么?我问,因为我希望自己用刮刮线涂抹自己。空气空间/锚法似乎更具技术性。如果我必须带入梅森,我相信它会提高我的成本。
Sean,
Q. "If direct contact with the ICF wall works below grade, why does direct contact with the stone facing not work?"
A. Good question. I invite GBA readers who have built ICF homes to comment. My guess is that an ICF wall, with two layers of EPS, won't be adversely affected by the installation of stone without an air space. Where it gets tricky is at the windows.
I would include the air space if this were my home, because the air space facilitates window flashing.
肖恩,你最终做了什么?
I appreciate your comments Martin, particularly with mention of the window flashing. We were thinking about taking our stone wainscotting over the ICF just above the bottom of the tallest windows, but now I think we should keep it below for this reason.
JLC的这篇文章建议将泡沫粗糙,只有一点点(就像僵硬的扫帚),无需紧固件,锚,网格,板条或空气空间/ Rainscreen。

Affixing the stone to wall depends on the type of stonework being done. If the stone veneer shelf is relatively deep - say a 9" average - and especially if the stone is relatively flat and not a round cobble-type stone the wall will be self supporting to the the extent that brick ties screwed into the icf plastic ties will be all that's needed. Check the icf manufacturer for screw recommendations. If you're appling a thin veneer that won't be "stacked" you'll be better off installing a continuous diamond lath that you can parge the mortar onto for adhesion to the wall. Either way you need to install weeps that will help water that could get behind the stone veneer makes its way out. Is this diy or are you hiring a mason?
We have done both natural stone and veneer stone on our ICF. The natural stone was done by including a ledge in the ICF which supported the vertical load, and nothing over the styrofoam of the ICF; both inside the house (20' tall stone fireplace) and outside.
我们还在房子外安装一些石板。我安装了一层#30沥青纸,然后是一层机身拧入ICF中的嵌入式条带,然后典型的刮刀系统在屏幕上(拧入相同的条带),然后是石板。矫枉过正?也许,但是它的房子所以我可以做我想做的事情!
