The rooftop waterproofing business boasts an unrivaled history and track record as our main business since our founding. Positioning it as an indispensable technology for protecting the quality of social assets and passing on what is truly valuable to the future, we always humbly look at ourselves from a new perspective. Steady research into better materials and construction methods is always developed from the perspective of security and life cycle of the entire building. The theme of this is to provide customers with intangible economies of scale by making a wide range of proposals for all buildings, and it is also a guideline to play a role in enabling comprehensive engineering of building environment creation.
