Course Objective

The main principle in foundation engineering is to support the building on shallow foundations, especially on single square footings. The existing soil at a construction site may not always be totaly suitable for supporting structures on single footings in such a condition. If it is not possible to use single footings, one can use mat foundations. In Turkey, engineers prefer to construct buildings on deep foundations when the building loads are high. But, shallow foundations on improved site may stil offer cheaper way. In this lecture it is intended to mention the most economical and convenient soil improvement techniques for Turkey.
