摘要

Base construction of a foundation ditch in pressing ground water comprises at least one sealing base (1) consisting of a natural water-impermeable layer or an artificial water-impermeable layer as the sealing component. Grown soil (3) lies above the sealing base and below the foundation base (8). A layer (4) artificially manufactured by changing the grown soil and having a greater water-permeability than the gown soil lies above the sealing base and below the foundation base. Preferred Features: The water-impermeable layer is approximately 0.05-0.5 meters thick.
