Shear Strength Comparison Between a Foundation Stud Anchor (on left) and a Shear Transfer Angle (on right)
Image
Termite shield extends under sill plate and through brick veneer below the through-wall flashing and weep holes.
Image
Termite shield is installed at the top of the foundation wall before installing sill plates; all seams and holes are sealed with epoxy
Image
Image
The components of a framed wall include from inside to out: gypsum, wood studs, OSB or plywood sheathing, and siding.
Image
The cripple wall hiding the post-and-pier foundation of this wood framed house toppled when the house was shifted partially off its piers by an earthquake
Image
The elevated concrete floor over this concrete column foundation uses rigid foam on its interior surface to reduce thermal bridging and risk of floodwater damage
Image
The flat retrofit foundation plate is used to connect the concrete foundation to the sill plate from the exterior of the building as part of a seismic retrofit
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 polyethylene ground cover in the crawlspace is continuous at interior posts and piers
Image
Image
The rails on these stairs were enclosed with siding, presenting a greater obstacle to the flow of flood water and contributing to the flood damage shown here.
Image
The sheathing has rotted because there was not a sufficient drainage gap behind the stucco cladding
Image
The universal retrofit foundation plate is used to connect the concrete foundation to the sill plate as part of a seismic retrofit
Image
This basement is insulated on the exterior with rigid foam over dampproofing, with granular backfill and footing drains to facilitate drainage away from the foundation, a termite shield to protect from pests, and cellular PVC to protect the rigid foam.
Image
This breakaway wall design made of decay resistant lumber is compliant with the National Flood Insurance Program.
Image
This concrete block foundation cracked due to lack of steel rebar reinforcement.
Image
This exterior insulated slab-on-grade monolithic grade beam foundation is protected from pests by termite shield at the sill plate, borate-treated framing, flashing at end of wall insulation, brick veneer over slab-edge insulation, and rock ground cover.
Image
This home constructed in a V Zone in Bolivar Peninsula, Texas, had the bottom beam of the lowest floor at the BFE (dashed line) but the estimated wave crest during Hurricane Ike was 3 to 4 feet higher (solid line).
Image
This home was elevated above the Design Flood Elevation and the pre-existing first story became the second story.
Image
Image
This house with an insulated slab is protected from pests with a termite shield at the sill plate, borate-treated framing, insect screen covering bottom of furring air gap, and brick veneer over slab-edge insulation
Image
This house with interior insulated crawlspace is protected from pests with termite shield at sill plate, borate-treated framing, flashing at end of wall insulation, and a termite inspection gap at the top of the rigid foam
Image
This left-to-right sequence shows the method of wall extension to flood-proof a masonry house on a slab foundation. Here the new, raised floor is wood-framed over a wet-floodproofed crawlspace, but using fill to create a new raised slab is also an option.
Image
This plumbing pipe is wrapped with a stainless steel mesh skirt that is clamped to the pipe before the concrete slab is poured to to keep out bugs and rodents
Image
Image
This raised-slab CMU and brick foundation includes flood-resistant features such as a sloped grade, capillary break under the slab (gravel or sand), vapor barrier under the slab (polyethylene sheet), and capillary break at the top of the foundation wall
Image
This raised-slab poured concrete foundation includes flood-resistant features such as a sloped grade, capillary break under the slab (gravel or sand), vapor retarder under the slab (rigid insulation), and capillary break at the top of the foundation wall
Image
This wood-framed wall is connected with framing anchors, metal strapping and ties, and anchor bolts to secure the roof to the walls and walls to the foundation
Image
Three different anchoring methods are shown for making the home more resistant to getting moved off its foundation in an earthquake.
Image
Three types of foundation walls: Stem-plus-wood stud cripple wall, reinforced concrete wall, and reinforced concrete block/masonry wall
Image
To control surface water, the land should slope away from the building on all sides
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
Image
Vented crawlspace cripple wall has seismic retrofits – plywood is added on interior that fastens to extra blocking added at sill plate and connected to foundation with new anchor bolts
Image
Image
Wire hardware mesh is fastened with a staple gun and screws to the wall to prevent pests from entering the building through small holes and cracks
Image
Image
Wrong - In floodplains, the interior grade elevation should be equal to or higher than the exterior grade as shown on right.
Image
Wrong - The pile foundation of this home nearly collapsed from coastal storm surges because the piles were not embedded deeply enough in the ground.
Image
Wrong - This surface downspout run-out is directed toward the foundation instead of away from it.
Image
Image
Wrong – Drain pipe has been cut and foundation penetration has not been properly sealed
Image
Image
Wrong – Piers set on individual footings with inadequate anchoring to the ground were twisted and toppled by a coastal storm surge, while those anchored in the concrete pad stayed upright.
Image
Wrong – Rain barrel installed without an overflow spout that terminates away from foundation
