Image
A method for preventing waterproofing issues at the intersection of a concrete pier, concrete retaining wall, and concrete slab.
Image
Impervious surfaces like patio slabs, sidewalks, and driveways that are within 10 feet of the home should slope away from the house.
Image
Place plants at least 18 inches from the building's walls and foundation and direct irrigation water to spray away from the structure.
Image
The “perimeter cutoff and dewatering” approach can be used to control groundwater in cases where the building foundation is below the groundwater table.
Image
Image
A common method of addressing significant groundwater leakage in the foundation is to line the entire foundation assembly, including the slab, with a drainage layer.
Image
A common method of addressing significant groundwater leakage in the foundation is to line the interior perimeter of the foundation with a drainage layer.

Image
Image
A dimpled rain mat and perforated drain pipe provide drainage around the basement foundation.
Image
A drywell, shown here used for downspout catchment, can also be used to receive water from a French drain.
Image
A method for preventing waterproofing issues at the intersection of a concrete column, concrete slab, and concrete pier.
Image
A method for preventing waterproofing issues at the intersection of a concrete slab and a rock anchor.
Image
A method to ensure waterproofing continuity across the elevator pit of a multistory multifamily building.
Image
A paint-on waterproofing covers the exterior and tops of the concrete block foundation walls and piers to block moisture moving up through the concrete, while foil-faced R-13 insulation lines the inside surface of the exterior walls.
Image
A sprayer-applied waterproofing covers the grout-filled top course of concrete foundation blocks to prevent moisture migration from the ground into the framing.
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
Any holes through the vapor barrier installed over the basement floor slab are thoroughly sealed as part of the foundation water barrier system.
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
Building perimeter detail view of the recommended approach for groundwater management in cases where the foundation is entirely above the groundwater table.
Image
Buoyancy force on dry floodproofed homes with deep basements leads to possible foundation damage
Image
Image
Comprehensive above-grade water management details for a crawlspace foundation include a capillary break over the crawlspace floor, slope the surface grade away, installing gutters that slope away, and capillary break under sill plate.
Image
Comprehensive water management features include a capillary break (≥ 6-mil polyethylene sheeting) at all crawlspace floors
Image
Concrete (4 inches thick at 5% slope) provides a pest-resistant perimeter around the foundation
Image
Concrete pavers set in 4 inches of sand provide a pest-resistant ground break at the building perimeter.

Image
Design the roof, walls, foundation, and site to drain water away from the structure on all sides.

Image
Effectively manage below-grade water in urban sites to prevent moisture issues in new and existing buildings. This foundation wall has been waterproofed to prevent water infiltration.
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 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
Image
Good water management practices like sloping grade away from house, and installing gutters, perimeter drain pipe, a capillary break, and free-draining soils or drainage mat protect the foundation from water saturation.
Image
Green Coast Enterprises built this New Orleans home on piers so that the floor is 1 foot above the base flood level; borate treated framing and closed-cell spray foam insulation add to the home's moisture resistance.
