Basement Drying >> Can Carpet In A Flooded Basement Be Salvaged

Also, review the work of the Pat Huelman and the folks of the Cold Climate Housing Center. Pat and his peoplehave done a lot of work in this area. And he and Dick Stone do a lot of training -- Affordable Comfort, the Duluth EDC conference, etc. I don't believe any oftheir workcontradicts the info Can Carpet In A Flooded Basement Be Salvaged in the "Builder's Guide: Cold Climates" book.
 
But they may well have info on the most recent "miracle" Can Carpet In A Flooded Basement Be Salvaged materials out there intended to "allow" building assemblies that will just never work. (Like this goofy idea that you can successfully put a functioning vapor barrieron the warm side ofa below-grade concrete wall!)

Thanks Don for making me aware of Pat Huelman group. I'll definitely review their findings.
 
Albert Schinazi onMarch 22, 2011 at 4:07pm Jim,
Your question and the subsequent responses got me thinking. I tell myself I should know the answer to this question but I found myself Can Carpet In A Flooded Basement Be Salvaged wavering a bit. I have "Cold Climates” but it has been awhile since I have reviewed it and looked at this wall profile. Out of curiosity I searched the web and here is what I found at an EPA site. http://www.epa.gov/indoorairplus/technical/moisture/1_12.html .
 
"An appropriate assembly for the inside of a basement wall consists of 1 in. of plastic foam board or closed-cell polyurethane spray foam followed by a stud wall with fiberglass insulation filling the Can Carpet In A Flooded Basement Be Salvaged cavities. This assembly is covered with moisture- and mold-resistant gypsum board covered by two coats of latex paint. The foam board serves two purposes: providing a capillary break between the foundation wall and the stud wall and keeping warm, humid basement air away from the earth-chilled foundation.
 
 It is good practice to put 1 in. of foam board beneath the sole plate of the stud wall and the basement floor and to leave a ½-in. gap between the basement floor and the bottom of the gypsum board. Doing Can Carpet In A Flooded Basement Be Salvaged so provides protection from minor floods and damp concrete floors.” Clicking the link provides additional explanation and context for this strategy. I wonder if this is consistent with the other resources mentioned.
 
If not i would like to hear others thoughts. You can find an excellent publication on this question at http://www.buildingscience.com/documents/reports/rr-1003-building-a . The publication presents many solutions and rates them on several criteria. They also conducted detailed thermal and moisture Can Carpet In A Flooded Basement Be Salvaged modeling. I put 2" XPS on my basement walls as a temporary way to add some insulation before I got to the task of finishing the basement walls.
 
 I did not seal the joints between the sheets or the gaps at the top and bottom of the sheets. I had lots of ice on the top of the foundation wall and ice at every joint and gap down to the soil line. A well-sealed vapor barrier at the foundation wall is absolutely Can Carpet In A Flooded Basement Be Salvaged critical to preventing moisture problems. After seeing the moisture/ice problems first hand, I think I will insulate the stud walls with closed cell foam to assure that I have no air leaks.
 
This will cost more but the peace of mind is worth it. I live in a very cold climate near Yellowstone National Park. We have had many consecutive days of -20 to -30 F this winter. I am sure this Can Carpet In A Flooded Basement Be Salvaged contributed the ice formation behind the XPS and on top of the foundation wall. The major structural components of a basement are the wall, the footing, and the floor (see figure 2-2). Basement walls are typically constructed of cast-in-place concrete or concrete masonry units.
 
 Basement walls must be designed to resist lateral loads from the soil and vertical loads from the structure above. The lateral loads on the wall depend on the height of the fill, Can Carpet In A Flooded Basement Be Salvaged the soil type, soil moisture content, and seismic activity. Because of the large number of variables involved in foundation structural design, final determination of wall thickness, concrete strength, footing dimensions, and reinforcing should be made after consultation of locally-enforced building codes or design by a licensed structural engineer.
 
 Concrete spread footings provide support beneath basement concrete and masonry walls and columns. Footings must be designed with adequate size to distribute the load to the soil. Freezing water beneath footings can heave, causing cracking Can Carpet In A Flooded Basement Be Salvaged and other structural problems. Unless founded on bedrock or proven non-frost-susceptible soils, footings must be placed beneath the maximum frost penetration depth or be insulated to prevent frost penetration.
 
 Concrete slab floors are generally designed to have sufficient strength to support floor loads without reinforcing when poured on undisturbed or compacted soil. The use of welded wire Can Carpet In A Flooded Basement Be Salvaged fabric and concrete with a low water/cement ratio can reduce shrinkage cracking, which is an important concern for appearance and for reducing potential radon infiltration. The slab should be poured against a control joint material so that it can move independently of the foundation wall.
 
Where expansive soils are present or in areas of high seismic activity, special foundation construction Can Carpet In A Flooded Basement Be Salvaged techniques may be necessary. In these cases, consultation with local building officials and a structural engineer is recommended. WATER / MOISTURE MANAGEMENT - In general, moisture management schemes must control water in two states. First, since the soil in contact with the foundation wall is always at 100% relative humidity, foundation walls must deal with water vapor that will tend to migrate toward the interior under most conditions.
 
 Second, liquid water entry must be prevented. Liquid water can enter from sources such as: Uncontrolled flows of surface water High water table Capillary flow through subsurface foundation assemblies Techniques for controlling the build-up of moisture in the Can Carpet In A Flooded Basement Be Salvaged basement wall assemblies are an essential component of the overall construction. Improper moisture management can lead to structural damage, damage to finishes or basement contents, and mold growth, which can be very costly to repair and hazardous to one's health.
 
The following construction practices will prevent excess water in the form of liquid water and vapor from infiltrating the Can Carpet In A Flooded Basement Be Salvaged basement. This is done by using adequate drainage and by the use of vapor retarders as shown in Figure 2-3.
