Gravity Retaining wall assures its stability by its own weight.These walls are majorly designed to eliminate the overturning effect of the lateral earth pressure and do not induce tensile stresses within the section.. Active earth pressure tends to deflect the wall away from the backfill. The main purpose of retaining wall construction is to retain soil; that is why soil lateral earth pressure is a major concern in the design. Most systems are mortarless. tf A retaining wall made entirely out of brick is known as a cavity wall.
