"Until you put it on a maamid that is meqabel tum'ah. Then it becomes
invalid for sekhakh, but still valid as a maamid. <span style="font-family:arial">Your sevara is that of the CI's chumerah"</span></pre><pre><font face="arial">I don't think this is related to teh Chazon Ish at all (and neither does R' Frank in Mikraei Kodesh). In the case I described above you have something that is kasher schach that is resting on a davar hamekabel tuma. Why should you arbitrarily say that it isn't called schach but a maamid? The Chazon Ish goes much further, The Chazon Ish holds that you can't even use metal screws to hold the walls together. </font></pre>
