| The base compound, “Otas-Eco,” is a urethane waterproofing material that is hardened by mixing with water. In addition to high watertightness, it contains no organic solvents and ensures the safety of the process of construction. |

| Characteristics |
The Otas-Eco combined method is a new type of DD method and an environmentally-conscious
product.
No solvents are used to form the waterproofing layer. Material containers
are reused and impact on the environment is minimal.
|
|
Without waste production, there is no need for waste disposal.
"Otas-Eco" eventually becomes completely rigid after reacting with the water and moisture in the air, and no liquid Otas-Eco material is left. Any remaining material is crushed and reused.
