A sad end for the innovative Cape Romano sea domes. (See link in comments.)\
\
The homes could\'ve survived, had the builder done a few things differently:\
\
1. Anchor the homes on moorings instead of fixed pillars. This would\'ve allowed them to move the homes as the sea bed, water levels, and shoreline changed.\
\
2. Use fiberglass / basalt mesh / rebar instead of steel mesh / rebar for reinforcement. Untreated cement is porous, so water eventually reaches the steel and causes it to rust. Rusted steel expands, which puts tremendous tensile pressure on cement. Cement is weak under tensile forces, and spalls (crack and break off), which eventually causes more steel to be exposed.\
\
3. If you do use steel reinforcement, don\'t use unwashed beach sand to make the concrete. Beach sand contains salt water which will attack steel.\
\
4. Use hurricane shutters on all the doors, windows, and other entry ways. This would\'ve prevented the hurricanes from damaging the interior.\
\
5. Make all major interior fixtures (wall penels, cabinets, tables, dressers, etc) with salt water resistant materials (concrete, stainless steel, tempered glass, and aluminum). No wood, no sheetrock, no organic fabrics. Put a high capacity drain in every room. Use marine rated wiring, pipes, and plumbling fixtures. Use styrocrete / closed cell perlite for insulation.\
\
6. Use additives like Xypex, PVA fibers to make the concrete more resistant to cracking and water intrusion.\
\
7. Coat the exterior with sodium silicate mineral paints. Such paints chemically bond with cement and are extremely resistant to sun/salt water.
