Foundation Basics – February 2014

A homes foundation is in direct contact with the ground and joins the buildings structure with the underlying zone of soil or rock. The foundation’s job is to transfer the structure’s load to the underlying soil or rock, without excessive settlement or movement.
*Movement of the soil beneath a home can severely damage the foundation.
Shallow foundations, as in most residential homes, are susceptible to seasonal movement from rainfall, drought, freeze/thaw cycles and transpiration of moisture thru the roots of large plants or trees.
Deep foundations reach depths that are not normally effected by seasonal environmental changes and are considered to be out of the zone of influence.
