Good morning! For a two-story brick house, mechanized installation is essential and strongly recommended. Mechanized installation of screw piles is specifically used when constructing foundations for heavy buildings like yours. A helical pile machine can screw large-diameter pile supports into dense, hard soil - something that's extremely difficult or impossible to do manually. The critical advantages for your project are: First, mechanized installation ensures precise installation of supports to the required depth with minimal vertical deviations. This precision is crucial for heavy structures where any misalignment could cause serious structural problems. Second, brick houses require large-diameter piles that can handle significant loads - these are too heavy and require too much torque for manual installation. Third, the machine can penetrate dense, hard soil layers that manual crews would struggle with, ensuring piles reach proper load-bearing strata. Fourth, mechanized installation is much faster for the number of piles a two-story house requires. The investment in mechanized equipment is justified by the load-bearing requirements and structural integrity needs of heavy buildings. Details at
