Retaining Walls ~ the major function of any retaining wall is to act
as on earth retaining structure for the whole or part of its height
on one face, the other being exposed to the elements. Most small
height retaining walls are built entirely of brickwork or a
combination of brick facing and blockwork or mass concrete
backing. To reduce hydrostatic pressure on the wall from ground
water an adequate drainage system in the form of weep holes
should be used, alternatively subsoil drainage behind the wall could
be employed.Retaining Walls up to 1 m High---1
