Interesting product. Anyway, the guy that gave the presentation said that it's surprising the number of projects that they bid on (they do chemical treatment as well) that still specify Dursban.

In regards to chemical pretreatments, we never specify the actual product, instead we provide a link to the state agriculture link for approved pesticide products and let the GC make the choice. Jerry Tims AIA, CSI Senior Member Username: jtims Post Number: 79 Registered: 04-2005 Posted on Monday, May 04, 2009 - 02:41 pm:    I don't even provide any links. I just spec "any EPA approved chemical". As to your specific issue, I'll bow out at this point since I've never heard of a barrier sand treatment.

I will check my literature and get back to you.

I was asked to specify it for a remodel of an LDS temple in Hawaii.

Are they specified in addition to the termite requirements in the IBC or as an alternate.

Shipping sand to Abu Dhabi.... Priceless! J. Peter Jordan Senior Member Username: jpjordan Post Number: 330 Registered: 05-2004 Posted on Tuesday, May 05, 2009 - 02:37 pm:    Termites in Abu Dhabi? I thought these guys needed some moisture to live. The basaltic termite barrier was a good system in theory, but it would seem to me to be quite difficult to achieve in the field (I never specified it myself, but was intrigued). The size of the particles were such that they were too big to be moved by the critters, but created voids between particles that were too small to pass. Don't know if this would work on all species of termites. Mark Gilligan SE, CSI Senior Member Username: mark_gilligan Post Number: 160 Registered: 10-2007 Posted on Wednesday, May 06, 2009 - 05:39 pm:    IBC Section 2304.11.2 requires that wood be protected against decay. Thus if the barrier sand or mesh products are proposed to be used in place of chemical treatment of wood it is not clear how protection against decay will be provided. Both systems will allow moisture to pass. Would recommend that all chemical treatment systems be covered by AWPA standards. Because of differences in the review processes I am not convinced that chemical treatment systems that do not have AWPA acceptance but rather rely on evaluation reports to document compliance, are subject to the same level of review.
