Image
Right--The polyethylene ground cover for this insulated crawlspace is taped at seams and around posts before the insulation and slab are installed.
Image
Rigid foam insulation and a thin slab were installed over the dirt and gravel of this sealed crawlspace
Image
Rigid insulation and water control layers are installed on the exterior of a flat foundation wall; spray foam insulates the rim joist
Image
Image
Image
Image
Spray foam extends down the foundation wall to the slab, which has been retrofitted by adding dimple plastic drainage mat and rigid foam insulation.
Image
Spray foam extends down the inside of the foundation wall to the uninsulated slab; because the wall lacked exterior perimeter drainage, the slab was cut and an interior footing drain was installed.
Image
Spray foam insulation extends down the foundation wall to the slab, which has been retrofitted by cutting the slab to install drainage mat against the wall and a new perimeter footing drain, along with rigid foam plastic above the slab.

Image
The basement is constructed with precast concrete walls lined with R-21.3 foil-faced rigid foam while an R-10 layer of XPS rigid foam covers the ground under the slab.
Image
The basement is half in and half out of the ground with only 4 feet below grade, which allows for full 36-inch-tall windows that are completely above grade.
Image
The basement walls’ interior framing is set in 3 inches from the concrete to allow space for closed-cell foam that is sprayed directly on the concrete, then blown cellulose is added to fill the wall cavity.
Image
The daylight basement walls are made of concrete walls with integrated rigid foam and steel-faced concrete studs.
Image
The existing slab is retrofitted by coating with epoxy paint, then installing rigid foam insulation and a floating subfloor.
Image
The existing slab is retrofitted with epoxy paint, rigid foam insulation, sleepers (furring strips), and subfloor.
Image
The goal of foundation moisture management is to construct the basement, crawlspace, or slab in a way that keeps moisture from getting in in the first place
Image
The rim band connecting the insulated precast concrete basement walls to the floor joists above is spray foamed to provide air-sealing and insulation in this hard-to-seal juncture.
Image
The risk of hydrostatic pressure differences in a flood is reduced when the interior grade of the crawlspace is higher or equal to the exterior grade.
Image
The water heater and other appliances are located above the Base Flood Elevation.
Image
This basement is insulated on the exterior with rigid foam over dampproofing, with granular backfill and footing drains to facilitate drainage away from the foundation, a termite shield to protect from pests, and cellular PVC to protect the rigid foam.
Image
This exterior insulated slab-on-grade monolithic grade beam foundation is protected from pests by termite shield at the sill plate, borate-treated framing, flashing at end of wall insulation, brick veneer over slab-edge insulation, and rock ground cover.
Image
This floor assembly above a vented crawlspace controls vapor and heat transmission by using foil-faced isocyanurate rigid foam insulation installed underneath the floor joists and fiberglass insulation in the floor joist cavities
Image
This house was designed with half of the basement above grade, allowing 36-inch-tall windows for egress and daylight on both sides of the house.
Image
Image
Image
Image
Unvented air-sealed crawlspace is insulated along the perimeter walls with rigid foam
Image
Image
Water-proof materials cover the exterior side of crawlspace windows in a crawlspace retrofit, while foil-faced rigid foams seals and insulates the inside face of the openings
Image
Wrong - Air leakage from the conditioned space to the basement foundation wall can lead to condensation or moisture issues in a conventional blanket insulation installation.
Image
Image
Image
Image
Wrong - Moisture from within the basement foundation wall can migrate into the insulation cavity in a conventional blanket insulation installation.
Image
Wrong - No air barrier is present between the floor system and unconditioned space.
Image
Wrong - Plastic-covered blanket insulation that is installed directly against concrete walls with no rigid foam or closed-cell spray foam covering the concrete could trap moisture coming through the concrete, leading to mold, moisture, and odor problems.
Image
Image
Image
Wrong - The basement blanket insulation is loosely attached to the interior of the basement wall, does not cover the entire wall, is not sealed at the edges, and is not installed over rigid foam that covers the entire surface of the foundation walls.
Image
Wrong - The below-grade concrete does not have the correct construction to be impermeable to moisture because the lumber is untreated and against the concrete that lacks waterproofing.
Image
Wrong - The fiberglass blanket insulation has no perforated vapor retarder, does not cover the entire basement wall, is not sealed at the edges, and is not installed over rigid foam.
Image
Image
Wrong - This plastic-covered blanket insulation is not perforated, does not cover the entire basement wall, is not sealed at the edges, and is not installed over rigid foam.
Image
Wrong – A poorly sealed window and window well allow bulk water to enter the crawlspace from ground that slopes toward the structure
