-class 5: basalt black blue fill Bureau Foundation put lightning-dust. Rock the block, exist form the cornerstone in size from 20 to 50 cm. distribution of scattered over the area. This is the layer of weathered basalts form platform to roll, this class is not uniform distribution focus areas. This heterogeneous layer distribution in the whole line, the depth of the soil layer from an average of 0.6-2.6 m, separate from paragraph g2-g5 is fairly shallow, especially g3-g4. so in the process of constructing the need redefine exactly the magnitude of compression resistance, to choose construction
