The traditional methods of soil monolith preparation are not useful in marginal mountains andoverseas area due to lacking of reagents and inconvenience of transportation. In addition, the traditionalmethods require much quantity of chemical resin, which cause environmental pollution. This study aimsat developing a new method of soil monolith preparation to improve labor efficiency and environmentalsoundness. A newly developed 'soil monolith kit' package contains four (4) sheets of cloth (25cm × 25cm)soaked in polyurethane resin (Tomack NS-10) in a sealed plastic bag. We named this kit as 'PEDOMO-TAPE'. The resin soaked cloth is directly put on smoothed soil profile and the covered area of cloth is 100cm length, 25 cm width. At least, one hour is required for hardening the resin. After checking the statusof resin hardness, the resin-treated soil peel is carefully detached and transferred onto mounting board. The required characteristics of cloth are various, holding resin as much as possible or dischargingresin, because of different soil physical property. We selected two different kinds of cloth, one is flannelof the 100% cotton to hold resin, and another is non-woven fabric to discharge resin. These are chosenwhen packing a kit. We also selected oxygen impermeable plastic to pack a kit.
