When the basement wall is insulated from the interior, there are a few different ways to achieve minimum R-values. This article illustrates the three most common options: continuous rigid insulation, a combination of continuous rigid insulation and insulation batts, or closed-cell spray foam. Regardless of the insulation method you choose, here ...
The plans are for a crawl space but elevation gives me a basement. 12" is about 2-3 grand more. i think I may use 12" on the wall that has the most fill. the rest of the walls will get 8", they get less fill. thanks for the help . Matt | Jul 05, 2008 01:40am | #6. Look at your code book.
ABOUT ICF WALLS. ICF homes are tight, strong, and quiet— One way to insulate a poured concrete wall is with permanent forms made of insulation. Insulating concrete forms (ICFs) are panels or hollow blocks that are stacked, braced, and then filled with concrete. They are most commonly solid pieces of rigid foam, but some are composites of ...
If you plan to insulate your basement walls with spray foam, the best approach is to frame your 2×4 walls before the foam is sprayed, leaving a gap of 1-1/2 in. to 2 in. between the back of the studs and the concrete wall. The gap will be filled later with spray foam. If you live in an area where termites are a problem, your local building ...
One variety is the thickened-edge slab. Around the outside of the foundation, the concrete might be 10 in. or 12 in. thick, while concrete in the middle of the slab would be less than half that. The idea is that the thicker edge bears the weight of the exterior walls, just as a separately poured concrete footing would.
The difference is in the type of load the block wall is subjected to. The higher the wall (the deeper the foundation), the more it wants to bend in due to the lateral load of earth/water. Usually, building departments have some guidelines on reinforcing basement walls. *Grout without steel (rebar) is almost wothless.
Stone, brick, concrete block, and concrete all have specific characteristics that challenge a finished basement. Stone, brick, and concrete-block foundation walls are all mortared systems. The amount of mortar and the manner in which it was laid (neat and full vs. sloppy and spare) help determine the ability for water to penetrate the ...
Apply a thick bead of Loctite PL 300 glue around the perimeter of each sheet of foam board, then press it against the wall. You can lean a 2x against the sheet to hold it in place until the glue sets. Then seal all of the joints to block moisture leaks. DAP 230 or HVAC mastic work well for joints and small gaps.
Dimple mat, or dimple board, is a product that seems to fall somewhere in between simple asphaltic dampproofing and a full-on waterproofing membrane. Dörken’s version is called Delta MS. It is a high-density polyethylene sheet combining recycled and virgin materials whose surface is studded with 5/16-inch-tall dimples.
If you know the veneer will need a finished cap, make sure you leave enough room for it. Up to 2 in. more than the thickness of the capstones is enough space to angle the stone away from the house to shed water. Tap capstones with a rubber mallet to set them in position. Make sure the capstones are level.
