«+»  Cheap  Sturdy

«-»  V ery low elevation  T he potential for large heat losses  T he lack of access from below for utility lines

Slab-on-grade foundations are commonly used in areas with expansive clay soil

Deep foundation Reasons:  very large loads  poor soil  site constraints

Made of:  Timber  Steel  Reinforced concrete  Pre-tensioned concrete Length: 4 – 12 m

Prefabricated piles are driven into the ground using a pile driver.

When the weight reaches its highest point it is then released and smashes on to the pile in order to drive it into the ground

A drilled pier is a deep foundation system that is constructed by placing fresh concrete and reinforcing steel into a drilled shaft.

Pad foundation consists of columns Columns:  Circular  Square  Reactangular

Soil that is not liable for movements

«+»  Economical  Strong  Does not need additional hydroisolation works

«-»  Lightweight buildings  Can´t be built subbasement
