| Characteristics |
Use of waterproofing materials with high quality and good properties
In "Quick spray," the amount of discharge and stirring is controlled mechanically, which enables the constant formation of a good-property urethane coating (specific gravity of 1.0) of chosen thickness.
Shortened construction period due to use of rapid-hardening materials
and mechanized process of construction
Rapid-hardening urethane is used. Time needed for construction is greatly shortened by mechanization.

Overcomes the disadvantages of exposed waterproofing
The disadvantages of exposed waterproofing such as blisters in the waterproofing layer and rupture of the waterproofing layer because of cracks in the base have been overcome. This is a degassing insulation combined waterproofing method which provides outstanding durability and low maintenance, not to mention outstanding watertightness.
