An exhaust fan pulls damp air out of a retrofitted sealed crawlspace while drawing in dry air from the living space
Image
Basement plan showing sump pump location and perimeter drain that empties to the sump pit
Image
Because the above-grade potions of the wall lack exterior insulation, condensation and even ice form during cold winter conditions
Image
Before sealing and insulating the crawlspace, the windows were sealed, the window wells backfilled, and sumps pumps were installed that discharged to the gutter downspouts
Image
Exterior XPS basement insulation is correctly installed to completely cover the foundation wall
Image
Foil-faced rigid foam and spray foam can be used to insulate a basement on the interior; use good moisture management techniques to keep the basement dry
Image
ICF bricks are stacked to form hollow walls that are reinforced with steel rebar before the concrete is poured in

Image
Right – A sump pump with a perforated sump pit was installed in the crawlspace slab to reduce water accumulation under the slab
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
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--The polyethylene ground cover for this insulated crawlspace is taped at seams and around posts before the insulation and slab are installed.

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 – A poorly sealed window and window well allow bulk water to enter the crawlspace from ground that slopes toward the structure
Image
Wrong – The vapor barrier is not secured to the walls of this crawlspace.
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
