Crawlspace foundation and floor systems are economical to build and are ideally suited to temporary installations where buildings are to be relocated, such as on leased land.
Raised floor systems also support the floodplain management principle of “no adverse impact” on the rights of neighboring property owners and communities. Slab-on-fill developments can alter the natural floodplain, causing more frequent flooding and higher flood peaks. A pier-and-beam foundation is far less disruptive to natural surroundings than slab-on-grade. Slabs smother the root systems of valuable trees, but raised floor pier footers cause minimal disruption to roots, saving trees that might otherwise be removed near a slab. Future structural modifications, additions, or repairs can be easily accomplished with a raised floor. These tasks can be completed with less environmental damage and lower energy output.
Health and / or Social Benefits
The raised floor home nurtures the body and soul. The subtle yield of a raised floor joist system means walking comfort and less stress on back, legs, and feet.
If you are just leasing land, raised floor foundation allows you to move the structure and keep the investment in your structure.
Future structural modifications, additions, or repairs can be easily accomplished with a raised floor. These tasks can be completed with less environmental damage, lower energy output, and without expensive and complex technologies.
Meeting code in flood zones is easy with a raised floor foundation. Simple hardware connections resist lateral water movement and flotation. Raising lowest floors to exceed design flood elevation without fill (limited in some coastal zones) is easy.
