Image
Buildings damaged by a hurricane storm surge: upper homes on gulf shoreline were hit by large waves above the lowest floor, lower left home on bay and right school 1.3 miles from gulf shoreline were hit by surge and small waves.
Image
For homes built in V Zones a registered professional engineer or architect must certify that the lowest floor elevation is above the BFE and piles and structure are anchored to resist flotation, collapse, or lateral movement due to combined wind and water
Image
Framing anchors, anchor bolts, joist hangers, and bridging pieces all help to tie the components of the floor system together and to the foundation to increase resistance against seismic forces.
Image
ICF foundation walls wrap the floor slab in R-22 of insulation while the entire space under the slab is covered with 4.3 inches of closed-cell spray foam.
Image
In Coastal A Zones and V Zones best practice is to construct the home so the bottom support of the lowest floor is above the 100-year wave crest elevation.

Image
Recommended construction for homes in Zone B (areas of moderate flood hazard between the 100-yr and 500-yr flood) and Zones C and X (areas of minimal flood hazard above the 500-yr flood).

Image
Right - Foil-faced polyisocyanurate insulating rigid foam sheathing is installed below the floor framing of this house built on piers; however, the seams should be sealed with metal taped and the plumbing elevated and protected.
Image
Right - Retrofit of an existing basement slab by adding dimple plastic mat, rigid foam insulation, and a floating subfloor.
Image
Right - The existing basement slab is retrofitted by installing a dimple plastic drainage mat, rigid foam insulation, and a floating subfloor.
Image
Rigid foam insulation and a thin slab were installed over the dirt and gravel of this sealed crawlspace
Image
The components of a framed wall include from inside to out: gypsum, wood studs, OSB or plywood sheathing, and siding.
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
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 is heated with in-floor hydronic radiant heating tubes that were installed on top of the R-20 rigid foam under-slab insulation.
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
