A block assembly for constructing a seawall along an embankment. The block assembly is comprised of two types of blocks, a first block and a second block. Each block includes two half-circular type projections lying parallel to one another, seawater holes for discharging sea water are formed in a front wall between the half-circular projections of each block to prevent the loss of blocks and to decrease wave power. In an upper and lower end portions of the front wall of both blocks, projections are reciprocally formed with spaces, and a fixed supporter is formed on a backside of the front wall.
