Basement Drying >> What Is The Best Way To Dry Out Carpets After A Ba

Extruded polystyrene, expanded polystyrene, and rigid mineral wool panels are routinely used in below-grade exterior foundation insulation systems. Extruded polystyrene has a rated R-value per inch of 5, and mineral wool is about R-4.2 per inch. 

Expanded polystyrene panels are also used, with a rated R-value of 4–4.5/in., depending on the density of What Is The Best Way To Dry Out Carpets After A Ba material chosen. Though commonly thought to be unaffected by moisture, the literature suggests that both rigid polystyrene products when installed below grade lose R-value over time because of an increase in moisture What Is The Best Way To Dry Out Carpets After A Ba content (Crandell 2010; Horvath 1999). 

This degradation can be mitigated by ensuring positive drainage of water; both types of polystyrene do absorb significant amounts of water in very wet conditions, with a What Is The Best Way To Dry Out Carpets After A Ba corresponding decrease in R-value. 

Rigid mineral wool What Is The Best Way To Dry Out Carpets After A Ba panels (including rigid fiberglass) are permeable to vapor and water. As such, high moisture content could compromise the thermal performance of the material. 

In addition, What Is The Best Way To Dry Out Carpets After A Ba water drains freely through these materials, and the potential for waterborne silt to accumulate in the panel must be considered. 

Some studies suggest that, given good drainage at the footing and proper assembly design, this silting does not occur to a degree that would significantly affect What Is The Best Way To Dry Out Carpets After A Ba thermal performance (Bomberg 1980; Edvardsen 1970). 

Additionally, What Is The Best Way To Dry Out Carpets After A Ba this free-draining property can prevent hydrostatic pressure from building up against foundation walls, assuming footing drainage is effective. 

Because our optimal solution (Section 6) does What Is The Best Way To Dry Out Carpets After A Ba not involve adding footing drainage where none exists, this is a limitation of water-permeable materials for our application. 

No studies on thermal degradation because of moisture accumulation were found, although Bomberg (1980) notes that "although mineral fiberboard drains from most of its height, there is a layer of about 20 cm at the bottom of the insulation which is practically What Is The Best Way To Dry Out Carpets After A Ba saturated with water.

Rigid board insulation products are installed before foundation backfilling. They are fastened mechanically to the foundation wall. Above-grade portions of the insulation must be covered with a durable material to resist mechanical damage and What Is The Best Way To Dry Out Carpets After A Ba ultraviolet light exposure.  

Water Management These materials are usually not employed as the sole line of defense against soil-borne moisture intrusion. They are typically applied over a waterproofing or damp-proofing material applied to What Is The Best Way To Dry Out Carpets After A Ba the foundation wall. 8.1.4 

Cost Because both case What Is The Best Way To Dry Out Carpets After A Ba studies in Section 3.3 had very similar costs per square foot, one (the Duluth example) serves as a model to predict costs on the prototype house. The cost breakdown of the Duluth house is as follows: 

Excavation $2,920 3-in. XPS $918 Membrane $484 Stucco $275 Misc. fasteners $123 These data What Is The Best Way To Dry Out Carpets After A Ba represent a tentative cost for the prototype house. 

Removing the stucco from the price allowed comparison of functional equivalents with excavationless examples, which do What Is The Best Way To Dry Out Carpets After A Banot include stucco or other finish materials. 

All the other costs were normalized to conform to the area of the prototype house foundation, to reflect the varying costs of the three insulation types, and the reduction in R-value from the What Is The Best Way To Dry Out Carpets After A Ba case study to around 10 for the prototype house. 

The predicted What Is The Best Way To Dry Out Carpets After A Ba costs are: Rigid mineral wool (R-10) $6,807 Extruded polystyrene (R-10) $6,748 Expanded polystyrene (R-8) $6,454 Cellular Concrete Cellular concrete is produced by mixing proprietary bubble solutions with Portland cement or Portland cement/sand slurry. 

The cured product can have a range of characteristics with respect to density, insulating What Is The Best Way To Dry Out Carpets After A Ba value, and water permeance. 

Cellular concrete is typically used as a lightweight fill material in conditions like roadbed construction over difficult soils, and What Is The Best Way To Dry Out Carpets After A Ba as an insulating material in below-grade pipeline applications. 

It is valued because of What Is The Best Way To Dry Out Carpets After A Ba its low density, ability to be permeable or impermeable to water, relative low cost, range of compressive strength properties, and insulating properties. 

We interviewed John Fodor, lead geotechnical engineer with Cellular Concrete Solutions, was interviewed about the properties of cellular concrete and its feasibility as a below-grade insulation material What Is The Best Way To Dry Out Carpets After A Ba for house foundations. 

John suggested limiting material consideration to those mixes using Portland cement slurries without sand, What Is The Best Way To Dry Out Carpets After A Ba because sand significantly increases density and thermal conductivity. 

Table 2 shows the critical properties of four mix designs in the lower-density (lower thermal conductivity) range of available products. Cellular concrete is produced at the job site using special equipment. A Portland cement slurry would be delivered What Is The Best Way To Dry Out Carpets After A Ba using a typical ready-mix truck rig. 

The cellular What Is The Best Way To Dry Out Carpets After A Ba concrete equipment produces the foam, which is mixed with the Portland slurry on site. In a continuous operation, it is pumped through a hose to the work site as it is mixed. 

Water Management Cellular concrete can be made using a range What Is The Best Way To Dry Out Carpets After A Ba of chemical formulations that control the properties of the bubbles that produce the cellular structure in the Portland cement matrix. 

The properties of these bubbles determine whether the resulting product is relatively permeable to water or not. The What Is The Best Way To Dry Out Carpets After A Ba most impermeable formulations are comparable in water permeability to standard heavyweight concrete. 

Controlling the chemistry used for the foam means that a range of permeability can be created that can What Is The Best Way To Dry Out Carpets After A Ba allow water to freely drain through the material. 

Cellular Concrete Solutions commonly What Is The Best Way To Dry Out Carpets After A Ba develops custom formulations that optimize the final material properties for particular applications. 

One option is to create a hygrophobic final product by using silica-based admixtures intended to modify What Is The Best Way To Dry Out Carpets After A Ba concrete and make it effectively waterproof. Such admixtures are capable of eliminating water penetration into the concrete under significant hydrostatic pressure. 

John indicated that What Is The Best Way To Dry Out Carpets After A Ba they had developed such products in the past, with good results. In homes with existing moisture intrusion issues and no foundation drainage, such a product might be a feasible option. 

Alternatively, if good foundation drainage (or very permeable soils) is present, it may be desirable to use a permeable formulation to What Is The Best Way To Dry Out Carpets After A Ba reduce hydrostatic pressure on the foundation wall. 

In cases with a high risk of moisture intrusion, a two-step process could be explored, with a sheet membrane attached to the foundation What Is The Best Way To Dry Out Carpets After A Ba and draped into the trench. 

The cellular concrete would be poured against that sheet, What Is The Best Way To Dry Out Carpets After A Ba trapping it between the cellular concrete insulation and the foundation wall. Because of the increase in steps, this is likely to increase cost. 

Minnesota has one installer for Cellular Concrete Solutions products: Cellular Concrete, Inc. Craig Hrkel, president of that company, felt generally that this project was a good application for his product. He recommends What Is The Best Way To Dry Out Carpets After A Ba installation of a 25 lb/ft3 product (R-1.5/in., R-9 total in a 6-in.
