    • PROBLEM TO BE SOLVED: To provide a water absorption type waterproofing mat capable of having light-weight, having the excellence in workability, controlling a cut-off performance and preventing the leakage of water from a hole resulting from the driving of a fixed pin.
      SOLUTION: The water absorption type waterproofing mat (A1) consists of a fibrous high water absorptive polymer (11) and a non-woven fabric formed of a fiber (12) other than the high hygroscopic polymer. The thickness of the non-woven fabric is, for example, 3 mm to 30 mm, and a compounding ratio of the fibrous high hygroscopic polymer (11) is more than 30 wt.%.
