Spray foam and termite treatment

In my estimation, you can generally wipe your arse with termite contracts when things go wrong, so I wouldn’t even account for that. Having said that, there is a very real problem of spray foam potentially masking termite activity, and, as the other poster mentioned, if you develop a leak, it’s potentially disastrous with closed cell foam (just ask me). But if you do nothing, you get moist air infiltration that can cause other problems in your subfloor, finished floor and wall cavities.

Unfortunately, high humidity environments present a host of issues when it comes to conditioned buildings. Educate yourself and pick your poison because there’s no fool proof decision…

Also, look into a moisture barrier under the back fill you’re bringing in, which can help. But if you’re still getting water under the house, that could also prevent drainage and add to your problem.

LSU Ag Center has some good free articles in reference to insulation with pier and beam houses that you should read.
