Any one have some insight they can share on writing a specification for Termite Barrier Sand with Dursban or a link to an informative website. Than ks. |

I believe the use of Dursban was banned in 2000. |

Jerry, you are correct about the Dursban, the architect sent me an old detail and I transcribed the item without even thinking. |

Last week we were given a product luncheon by the Termimesh folks (they're listed here in 4Specs). 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. |

Jerry, we recommended stainless steel mesh already in lieu of the sand barrier, but the architect is insisting that sand barrier is what the client wants - this is for a project in Abu Dhabi, I guess they have plenty of sand there, I just don't know how to spec it. 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. |

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. |

Jerome, I remember when I worked in Hawaii that a company had developed crushed basalt rock in a specific size and configuration so that termites could not get through it. I will check my literature and get back to you. |

David, It sounds like Basaltic Termite Barrier (BTB) as provided by Ameron Hawaii. I was asked to specify it for a remodel of an LDS temple in Hawaii. |

It does not appear thst these products are mentioned in the IBC. Are they specified in addition to the termite requirements in the IBC or as an alternate. |

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. |

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. |
