Chris Bernhardt Posted April 7, 2009 Report Share Posted April 7, 2009 I called out a patio poured against hardy plank siding on new construction, and builder says that he's been thru this before with other inspectors and has an OK from someone that it's OK to do. Are there any exceptions to pouring concrete against siding? Even if you use some sort of isolation barrier? Chris, Oregon Quote Link to comment Share on other sites More sharing options...

Ask him to send it along. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Brandon Whitmore Posted April 8, 2009 Report Share Posted April 8, 2009 He probably got an OK from some building inspector who does not realize that the installation violates the manufacturers installation instructions. Quote Link to comment Share on other sites More sharing options...
hausdok Posted April 8, 2009 Report Share Posted April 8, 2009 Hi, I've talked directly to the tech folks at James Hardie about this. They are very clear - it can't be closer than two inches to steps, patios or anyplace where water will pond and you can't pour concrete against it. I've had builders claim that the vinyl "capillary break" behind the concrete will protect the siding. Well, it will protect the siding from moisture wicking through the concrete but it won't prevent water draining down the wall and in between the vinyl break and the concrete siding. I agree; he should produce the documentation - otherwise it's just another bogus myth/excuse he's using. ONE TEAM - ONE FIGHT!!!

Jim Katen Posted April 8, 2009 Report Share Posted April 8, 2009 . . . I've had builders claim that the vinyl "capillary break" behind the concrete will protect the siding. Well, it will protect the siding from moisture wicking through the concrete but it won't prevent water draining down the wall and in between the vinyl break and the concrete siding. And down here, it creates a concealed path for termites to enter the building. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Jim Baird Posted April 8, 2009 Report Share Posted April 8, 2009 How many ways can you spell and say, "No"? I hate to say it, but just because some dooffus city inspector turned a blind eye it never has made it right. I have been round and round with contractors over this issue. Difficult to correct but should not be ignored. Quote Link to comment Share on other sites More sharing options...
