It is feasible to build a 2 story building. The foundation is compacted by roller
No construction base is definitely not good. Roller compaction is only to improve the foundation and reinforcement, roller weight is twenty or thirty tons, compared with the weight of the two storey building is still a gap.
Directly hit the diameter of 90-100cm, deep into the hard mud 1.5m hole, and then steel and cement as a foundation, a pile is better than a roller.
Building foundation on the one hand is to bear the weight of the house, on the other hand, it is also necessary to ensure the uniform settlement of the house, otherwise the house will crack. No foundation, the house can not be built, there is no construction master dare to build.
