Image
Right – Foil-faced insulation was added after the crawlspace was dried and sealed by diverting water runoff, sealing off crawlspace windows and vents, and adding sump pumps and exhaust fan ventilation
Image
Right – Foundation drainage mat was installed over the waterproof membrane that covers the sealed crawlspace window
Image
Image
Right – The entire first floor and second floor of these modular homes were assembled in the factory and installed on an insulated concrete basement foundation on site.
Image
Right – The insulated concrete forms that are below-grade have a damp-proof coating to prevent moisture seeping into the foundation
Image
Right – The seam between the slab and the foundation wall is sealed with urethane caulk.
Image
Right – The slab is coated with two coats of epoxy paint to minimize moisture transfer through the slab from the ground.
Image
Right – This crawlspace window was completely sealed off on the inside and outside with air barrier and water-proof materials and the window well was filled in to an above-grade height to prevent bulk water from entering the crawlspace
Image
Right – Two inches of rigid foam was installed on the ground before pouring the basement floor slab while precast, pre-insulated concrete panels comprise the basement walls.
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
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
Image
Image
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
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
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 - Moisture from within the basement foundation wall can migrate into the insulation cavity in a conventional blanket insulation installation.
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 – A poorly sealed window and window well allow bulk water to enter the crawlspace from ground that slopes toward the structure
Image
Image
Wrong – The insulated concrete forms at the foundation do not have a damp-proof coating
Image
Wrong – This vented crawlspace has standing water because steps were not taken to address site conditions that led to bulk water flow into the crawlspace
