I am looking for advice on a project I would like to attempt in my own home. It is an 1840s cape with a granite block foundation, and basement is moderately damp. I am performing a full basement…Continue
"Funny you mention his name. I have not run this exact plan by him, but I had the opportunity to speak with him about a year ago and we discussed some of the concepts then.
I don't doubt that as a cellulose salesman he has a tendency to err on…"
"Bryan, you might try Bill Hulstrunk at National Fiber.
I bounced this scheme off of him some ago and he was encouraging. Use tu-tuff or something similar, keep the bulk moisture out and it'll be fine. He said that cellulose handles…"
The history of building materials in this country should make us all cautious about the toxicity of building materials. If you rewind the tape it's been one bad idea after another: lead paint, formaldehyde, asbestos, vermiculite, fiber…"
"Vapor barrier is happening regardless, but I have a choice as to whether I use even more chemicals or not.
Solving exterior drainage is not an option. I have already trenched in basement from pooling areas to sump pit that pumps to outside. No more…"
You say you dont want foam. What is foam? Plastic! What is the poly you propose to install? Plastic! So you can have plastic or plastic, which will it be?
Cellulose is going to tract the humidity level…"
"1st, forget cellulose, it is trash, hold moisture packs down, molds eventually, and rodents think they have found the Hilton hotel for rats.
Used closed cell foam. Insulates, stops moisture, sound proofs and so forth. "
"Ha, we're on the same wavelength. That's the big question--I'm still thinking about whether to jack or not. House slopes front to back about 2", so I'd like to address that. It's post and beam, so in theory I…"
"Thanks Norm, we'll have a couple of case studies when all is said and done.
Just curious, do you plan to jack the house and insert a capillary break under the sill? If no, how far up the wall are you going with EPDM?"
I am trying the same thing for most of the same reasons and also against advice to the contrary. We'll see how it goes.
I have a full basement with moisture problems--block on 3 sides, rubble on the fourth. I…"
I am looking for advice on a project I would like to attempt in my own home. It is an 1840s cape with a granite block foundation, and basement is moderately damp. I am performing a full basement encapsulation, after which I will have a 3-4" slab poured. I would like to build a 2x4 stud wall around the perimeter and dense pack with cellulose.Questions:1. Should I extend my vapor barrier all the way to the sub floor of 1st floor, or will the drying capability of the outside air above grade keep…See More
"Can you tell me more about how the plastic makes the moisture worse?
I understand that in the current situation ground moisture is drying to the inside of the house. By installing the vapor barrier, that prevents this evaporation,…"
"This example is the reverse of my suggestion. I would do high end vapor barrier against basement wall and then 2x4 stud wall inside of that, thus keeping the moisture on the rock/earth side and the biodegradable materials on the interior side."
"Really? Go back and read these posts again.... "play ground for mold."
I once did a basement with open cell foam (still oil based but less toxic than closed cell) with a high-end moisture barrier behind.
Bottom line you…"
"You can use whatever insulation material you want in the basement BUT you have to deal with all the moisture issues first or you have created a playground for mold, mildew, etc... As a reminder - plastic is not dealing with the moisture, just…"
