Image
A method for preventing waterproofing issues at the intersection of a concrete pier, concrete retaining wall, and concrete slab.
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
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
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 vapor barrier was installed on the floor of this crawlspace and extended up the walls then the foundation walls were covered with rigid foam.
Image
Because the above-grade potions of the wall lack exterior insulation, condensation and even ice form during cold winter conditions
Image
Building perimeter detail view of the recommended approach for groundwater management in cases where the foundation is entirely above the groundwater table.
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
Insulating a crawlspace foundation with “cripple wall” in warm climates; in Climate Zones 5+ replace the foil- or plastic-faced fiberglass batt/roll insulation with impermeable rigid insulation or closed-cell spray polyurethane foam
Image
Interior and exterior footing drains keep moisture away from the foundation. Spray-on water proofing helps the concrete foundation walls resist moisture.
Image
Intermittent water leaks have been injection sealed to prevent water infiltration into the foundation.
Image
Image
Right - The service penetration in the waterproofing membrane is well-sealed, and there is a drainage mat acting as a protective layer on the interior of the soldier piles and wood lagging.
Image
Right - This waterproofing membrane on the interior of a deep soldier pile foundation with wood lagging is continuous, and penetrations through the membrane have been sealed.
Image
Right – Because this home is in a coastal location that may flood the crawlspace is vented and the home is constructed on metal piers.
Image
Stucco is installed over rigid insulation, which is installed over a drainage plane consisting of a drainage gap and building wrap layer over the sheathing
Image
The “continuous waterproofing” approach can be used to control groundwater in cases where the building foundation is below the groundwater table.
Image
The “draw down” approach can be used to control groundwater in cases where the building foundation is below the groundwater table.
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 leaks in this foundation wall have been injection sealed to prevent water infiltration into the foundation.
Image
The polyethylene ground cover in the crawlspace is continuous at interior posts and piers
Image
The recommended approach for groundwater management in cases where the foundation is entirely above the groundwater table.
Image
The sheathing has rotted because there was not a sufficient drainage gap behind the stucco cladding
Image
The top course of these concrete masonry unit (CMU) crawlspace foundation walls and piers is filled with grout then sprayed with a waterproofing membrane that acts as a capillary break and prevents moisture from migrating into the framing material.
Image
This building foundation has a drainage layer located on the exterior of the waterproofing membrane.
Image
Traditional methods of site drainage, such as site grading, can be difficult to achieve on urban sites.
Image
Image
Wrong - Moisture from within the basement foundation wall can migrate into the insulation cavity in a conventional blanket insulation installation.
