Water-swelling material (WSM) is a fluid sealant obtained by blending high-absorbency
polymer, a filler, and a solvent by using a synthetic resin elastomer as the base material. In …

An evaluation method that can express the local leakage of leachate from joint sections in
steel pipe sheet pile (SPSP) cutoff walls is discussed in this study. In particular, the …

In this research, we conducted field installation and permeability tests for H-jointed SPSPs
with HH joints for their first application in the field; the tests were conducted in December …

This paper shows development and application potential of H-jointed steel pipe sheet piles
(SPSPs) with HH joints on vertical hydraulic cutoff walls used in coastal landfills. The authors …
