951,372. Blocks for moles and breakwaters. H. R. SVEE. Nov. 13, 1962 [Nov. 13, 1961], No. 42951/62. Heading E1H. H. A block 2 for making protecting layers on slopes of moles and breakwaters 1 is formed in such way that of its sides facing the neighbouring blocks at least one is made for interlocking with one of the neighbouring blocks, so that the blocks will prevent one another from moving in direction up from and normal to the slope la, and in such way that the cover made from the blocks will have at least one throughgoing opening 5 per block from the waterside 4 to the surface 3 resting on the slope, so that the pressure and suction forces to which the blocks are subjected due to the movement of the water are reduced.
