The pier foundation that lifts this home above flood waters is visible in this photo taken before the skirt walls were added.
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.

The seams of the rigid insulation are not taped and it will not provide a complete capillary break
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
These below-grade walls are insulated along the exterior with R-5 of bug-resistant high-density rigid fiberglass insulation installed over damproofing.
Image
This 4-inch layer of rigid foam insulation (R-20) will be sandwiched between two layers of concrete poured on site for a highly insulated foundation wall.
Image
This assembly can be used to thermally isolate heated or partially heated garages with slab foundations from the exterior in multifamily row houses/townhouses in IECC Climate Zones 3 and higher.
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 building foundation has a drainage layer located on the exterior of the waterproofing membrane.
Image
This coastal home was built on a flood-resistant pier foundation using hurricane- and moisture-resistant expanded polystyrene and steel wall panels and hurricane strapping.
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.
