ある。As described above, the water-repellent soil of the present invention has a particle diameter of 2 to 40 mm, each particle is covered with a clear composition film and has a glossy surface, and can be used for decoration. Or, it has the effect of repelling water like wax, so it does not retain water even when it rains and exhibits excellent effects as a non-grass soil, and the hardness of the surface coating material is large, light resistance, chemical resistance It has good resistance, fatigue resistance, adhesion, workability, etc. and prevents freezing and dew condensation as well as preventing the penetration of harmful ions. It is also suitable for interior decoration, exterior decoration, landscaping, graveyards, median strips, etc., and has the function of preventing the generation of algae and moss for a long period of time, since it is difficult to adhere to it and can be easily cleaned and cleaned. Also,
These earth and sand can be spread easily, and unlike pavement roads, there is no temperature rise due to the irregular reflection of the surface, which is a characteristic of natural stone, and there is space between particles and there is no heat conduction to the lower layer by sunlight, so summertime It has an excellent effect that it does not dissipate heat even after sunshine like a pavement sidewalk or concrete part.
