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
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
How to properly anchor a new home to its foundation with foundation sill plate, stem wall, and footing
Image
Image
Hurricane straps, hold-down connectors, and bolts help to transfer loads from the building’s walls to its foundation, increasing resistance to vertical and horizontal pressures acting on the building from wind, waves, or ground movement.

Image
Image
Right - A continuous load path connects the roof and wall framing to the foundation.
Image
Right - Basement slab with a capillary break of either gravel or a drainage mat.
Image
Right - Below-grade concrete has been properly sealed against moisture and is now having insulation installed.
Image
Right - Closed-cell spray foam covers the interior of the foundation wall and wall framing is placed to the inside of the spray foam.
Image
Right - Closed-cell spray foam is used to retrofit an existing rubble basement foundation wall.
Image
Right - Closed-cell spray foam was applied to the interior of a foundation wall.
Image
Right - Permeable rigid mineral wool insulation and appropriate water-management flashing details are integrated with new rigid foam siding to keep water away from the sill beam above the foundation wall
Image
Right - The slab-on-grade foundation is insulated with two layers (R-20) of XPS foam under the-slab and R-10 on the exterior of the stem walls.
Image
Right – Apply sealant around penetrations through foundation walls and along foundation wall seams
Image
Right – Examples of wall stud to sill plate and foundation and wall rod connectors and brackets.
Image
Right – Polyethylene sheeting vapor barrier is installed and sealed to the crawlspace walls with mastic
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 raised-slab, brick-and-block stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The raised-slab, CMU block stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The raised-slab, poured-concrete stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – Walls, windows, and wiring are installed in the factory for these modular homes, which are installed at the site on basement foundations made of insulated concrete wall panels.
Image

Image
Shear Strength Comparison Between a Foundation Stud Anchor (on left) and a Shear Transfer Angle (on right)
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
Image
Structural insulated panels offer a continuous layer of thermal protection and draft resistance around the home and come from the factory precut for fast assembly.
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 components of a framed wall include from inside to out: gypsum, wood studs, OSB or plywood sheathing, and siding.
Image

Image
Three types of foundation walls: Stem-plus-wood stud cripple wall, reinforced concrete wall, and reinforced concrete block/masonry wall
Image
To increase a masonry-walled home’s resistance to seismic forces, solid wood blocking is added between the roof rafters, anchors are added to connect the brick wall to the rafters and floor joists, building diaphragms are added, foundation braced
Image
Image
Uplift forces acting on the roof are met with roof-wall connections that distribute the forces down the walls and into the foundation along the continuous load path.
Image
Image
Image
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
Image
Image
Wrong – The insulated concrete forms at the foundation do not have a damp-proof coating
Image
Wrong – The polyethylene sheeting vapor barrier is not attached to the piers with mechanical fasteners
