PROBLEM TO BE SOLVED: To provide a coating method for bentonite-containing compacted soil by which reduction of moisture content of the bentonite-containing compacted soil can be suppressed and also construction is easily resumed.SOLUTION: A coating method is provided for suppressing reduction of moisture content of bentonite-containing compacted soil, and includes: a step of constructing bentonite-containing compacted soil 15 by scattering the bentonite-containing soil containing bentonite and water and compacting the same; and a step of applying hydrophobic resin on an exposed surface of the bentonite-containing compacted soil and forming a hydrophobic resin cured film 30 that covers the exposed surface. The hydrophobic resin does not dissolve into meniscus water on the exposed surface and does not take away the meniscus water from soil particles. Further, the hydrophobic resin does not allow water to permeate therethrough, therefore, acts as a barrier against water moving between inner and outer sides of the resin, immediately after applying the resin on the exposed surface until after forming the cured film. Also, the cured film 30 can be easily peeled off. |
