BLOCK FOUNDATION FOAM CONCRETE
A concrete block foundation sitting on a concrete footing is one of the more common foundation systems, especially if much height above the footing is necessary, such as on a hillside or slope or if the foundation is a basement wall or other below grade wall. Hairline cracks are common in block foundations, especially at the joints between the blocks.

They're usually not considered a concern unless water penetration is noted. On block foundations it is somewhat common to see efflorescence (a white powdery material) where water has penetrated or permeated through. If water penetration is a problem with any of these foundation types it may be necessary to seal the foundation with one of the many sealants available.

Each type sealant is good for a particular job so it will be necessary to examine closely your exact situation before researching the field of materials. Some sealers may be applied to the inside and some must be applied to the outside, which may require excavation. Foam blocks are fairly new and are not commonly found except in certain areas of North America. They are generally found in very cold areas where ground frost is prevalent. The inspector will not be able to ascertain whether reinforcing bars have been installed within the footings or foundation.
