Image
A dimpled plastic water barrier protects the insulated concrete form basement walls and carries any ground water down the walls to the footing drain to minimize the opportunity for water intrusion and frost heave.
Image
A dimpled rain mat and perforated drain pipe provide drainage around the basement foundation.
Image
A layer of pea gravel or crushed stone, 4 inches thick and sloped 5%, provides a pest-resistant ground break around the perimeter of a basement foundation
Image
An exhaust fan pulls damp air out of a retrofitted sealed crawlspace while drawing in dry air from the living space
Image
An uninsulated (or existing insulated) basement slab is retrofitted to reduce moisture transmission by sealing with epoxy paint.
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
Buoyancy force on dry floodproofed homes with deep basements leads to possible foundation damage

Image
Drainage and waterproofing system components in a basement, single perimeter drain system, footing detail
Image
Image
Exterior fiberglass insulation on this new home was (incorrectly) cut to terminate below-grade after backfill, which will expose the above-grade portions of the foundation wall to cold temperatures
Image
Exterior surface of below-grade walls finished as follows: For poured concrete, concrete masonry, and insulated concrete forms, finish with damp-proof coating
Image
Exterior surface of below-grade walls finished as follows: For wood-framed walls, finish with polyethylene and adhesive or other equivalent waterproofing
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
Image
Right - Below-grade concrete has been properly sealed against moisture and is now having insulation installed.
Image
Right - Retrofit of an existing basement slab by adding dimple plastic mat, rigid foam insulation, and a floating subfloor.
Image
Right - The basement walls are wrapped with 3 inches of XPS rigid foam that will be taped at the seams then covered with a dimpled plastic water barrier.
Image
Right - The existing basement slab is retrofitted by installing a dimple plastic drainage mat, rigid foam insulation, and a floating subfloor.
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 – The basement contains four 5,000-gallon rainwater holding tanks for this home which meets all of its water needs with rainwater.
Image
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--The polyethylene ground cover for this insulated crawlspace is taped at seams and around posts before the insulation and slab are installed.
Image
Rigid insulation and water control layers are installed on the exterior of a flat foundation wall; spray foam insulates the rim joist
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
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
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
