I am posting his response here along with my follow up.<br /><br />Jake (re the US Building Code requirements): The foundation thickness and rebar requirements have several variables: height of unbalanced backfill, overall wall height, and backfill type (soil pressure). Once these inputs are selected, you can choose from a thicker wall with less rebar, or thinner with more rebar. And definitely there are times you can't use 5.5" concrete. Particularly once you get to over 8' of unbalanced backfill in anything heavier than clay.<br /><br />My Reply: There is the difference between the US and Canadian code. The ONLY rebar allowed in a foundation if following the Part 9 Building code is that part of the code relating to ICF foundations. You cannot build a conventional site formed concrete foundation with Rebar in at least BC <b>UNLESS</b> you have that foundation engineered. There is no provision for rebar in the code except for when installing ICF.SENWiEco Designshttps://www.blogger.com/profile/16191232750350097838noreply@blogger.comtag:blogger.com,1999:blog-1252950587209456779.post-33612739420821165112015-06-02T20:35:42.233-07:002015-06-02T20:35:42.233-07:00Thanks Jake - I rechecked and then rechecked the r...Thanks Jake - I rechecked and then rechecked the ref. You are right, it is not Nudura, it is Faswall.

What reinforcement does your code call up then?SENWiEco Designshttps://www.blogger.com/profile/16191232750350097838noreply@blogger.comtag:blogger.com,1999:blog-1252950587209456779.post-84697054289518192402015-06-02T20:03:52.048-07:002015-06-02T20:03:52.048-07:00Sorry, I couldn't help one more comment!
Nudur...Sorry, I couldn't help one more comment!<br />Nudura is an all foam product, and always has been. I have been using them for many years. I won't link their sites here, but you will be able to verify that Faswall is whom you are really referring to.<br />Regarding the possibility of insect and rodent damage to a foam-based ICF; I will readily grant you that Durisol is superior in this regard. However, I have installed foam based ICF's on over 150 ICF's in the last 11 years without a (known) problem. I don't want your readers to forget that a foam-based ICF is superior to most wood framed assemblies out there.Anonymoushttps://www.blogger.com/profile/10083907268355816423noreply@blogger.comtag:blogger.com,1999:blog-1252950587209456779.post-54604008934154143932015-06-02T19:57:13.986-07:002015-06-02T19:57:13.986-07:00Sean;

So the structural requirements are identical for poured walls and ICF. In fact, the 5.5" thing came about not because of ICF, but because that is the size of a 6" wall tie for aluminum forms. An 8" wall tie is 7.5", etc. Their corner panels are set up this way too; in fact, one would have to invest in special corner forms to pour a true 8" wall.Anonymoushttps://www.blogger.com/profile/10083907268355816423noreply@blogger.comtag:blogger.com,1999:blog-1252950587209456779.post-32908522920191131572015-03-12T22:17:02.883-07:002015-03-12T22:17:02.883-07:00This comment has been removed by the author.SENWiEco Designshttps://www.blogger.com/profile/16191232750350097838noreply@blogger.comtag:blogger.com,1999:blog-1252950587209456779.post-82250364395828130032015-03-12T08:17:05.334-07:002015-03-12T08:17:05.334-07:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.com
