(Soil Pavement)| It is a mixture of soils (sand, granite soil) and epoxy resin used as binder. This mixture takes advantages of the soft color of soils As the strength is excellent, it is applicabe in areas where freezing is expected with no worry. |  | |
- The color becomes just same as the utilized soil to match the natural environment.
- As some free soils (sands) remains on the surface, natural soil like appearance is achieved.
- As it is water permeable, no puddle is generated in the time of rains.
- Pot holes in winter season are hard to be generated. Moreover, almost no corrosion of soils occurs.
- With adequate hardness, feeling of foot touchs is soft.
| - Walking lanes
foot paths, lanes in parks and garden.
promenade to shrines
courses for jogging
- Peripherals of Buildings
Peripherals of
