A retaining wall is a structure which holds behind the ground of a building or any other structure. The retaining walls stabilize the ground and/or the rock of the movement or the erosion of downward slope and provide the support for the vertical or close relation-vertical changes of category.

Batardeaus and watertight bulkheads, structures which the water of obstacle, are sometimes also considered retaining walls. Retaining walls are generally made of masonry, hones, brick, concrete, vinyl, steel or timber structural. Once popular like material of inexpensive reserve, ties of railroad fell out of the favor due to the environmental concern. They also break up finished time. The seminary retaining walls gained the favor above the concrete walls of pour-in-place or the treat-wood walls of construction. It is more economic, easier to install them and more ambient noise. The most important consideration in the suitable design and the installation of the retaining walls is that the maintained material tries to advance and downward slope due to gravity.

This creates a pressure of ground behind the wall which depends on the angle of internal friction (phi) and the cohesive force (c) of the maintained material, like the direction and importance of movement which the structure of reserve sudden. The side pressures of the ground are in general smallest with the top of the wall and increase towards the bottom. To put at the ground the pressures will push the wall ahead or to turn over it if not correctly addressed. Moreover, any subsoil waters behind the wall which is not absorbed by a drain cause an additional horizontal water pressure on the wall.
