Underground Waterproofing UG Hybrid Method
Gumlonfort Altax Spray Composite Method HUG-20Q-SP+G·A-B
Achieving both the reliability of asphalt waterproofing and the good fit of spray application! High-efficiency construction realized with standard materials at the top and urethane spray on the sides!
At the bottom and top, we use modified asphalt sheets that excel in waterproof reliability and workability on flat surfaces, while on the sides, we employ urethane spray that is excellent for side workability and processing of penetrations, creating a truly hybrid underground waterproofing method. Underground waterproofing is divided into various parts: bottom, sides, and top, and the construction methods, such as pre-application and post-application, differ, which means that the waterproofing of each part is connected to form a waterproof layer. Therefore, a single material is often insufficient for waterproofing, and there are many cases where a combination of multiple materials is desirable. Tajima Roofing, as a comprehensive waterproofing manufacturer, promotes the hybridization of underground waterproofing by leveraging its own materials, methods, and connection technologies.
