Shallow foundation construction example. A shallow foundation is a type of building foundation that transfers structural load to the Earth very near to the surface, rather than to a subsurface layer or a range of depths, as does a deep foundation. Customarily, a shallow foundation is considered as such when the width of the entire foundation is ...
This theory states that a foundation is shallow if its depth is less than or equal to its width. [4] Later investigations, however, have suggested that foundations with a depth, measured from the ground surface, equal to 3 to 4 times their width may be defined as shallow foundations.
Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.
In the United Kingdom most subsidence claims are for buildings at least 40 years old with shallow strip foundations. This is one of the most common types of foundations suffering from subsidence-related damage and according to the Building Research Establishment subsidence database, mass concrete underpinning was the most common underpinning ...
Deep foundations of The Marina Torch, a skyscraper in Dubai. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines.

Rockfall protection embankments belong to the family of passive rockfall protection structures, comprising flexible barriers or galleries in particular. [2] They are intended for rockfalls with kinetic energies up to tens of megajoules and are preferred over flexible barriers when the design impact is higher than 5000 kJ. [3]
