All materials are composed of solvent-free materials! High waterproofing and durability are achieved with the "composite waterproof layer" and "high durability heat-insulating topcoat."
The "HP-LCC Waterproofing Method" is fundamentally a three-layer structure constructed using machine spraying. The first layer is a rubber-modified asphalt sheet (self-adhesive type), the second layer is a spray polyurethane waterproofing material (1.5 kg/m²), or a high-performance polyurethane waterproofing material (2.6 kg/m²), and the third layer is a high-durability heat-insulating top coat (1.0 kg/m²). These materials are composed of almost solvent-free types. 【Features】 ■ The seamless "composite waterproof layer" of modified asphalt sheet and polyurethane coating achieves high waterproofing and water tightness. ■ Reduces the number of renovation works due to extended lifespan, significantly lowering LCC (lifecycle cost of the building). ■ Combines the "composite waterproofing" of the sheet and polyurethane with a high-durability heat-insulating top coat to protect the waterproof layer from solar heat and ultraviolet rays for an extended period. ■ There are no strong odors or noise from fixed pin installation during construction, minimizing the impact on residents and the surrounding environment. *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 - During renovations, the existing waterproof layer is not removed, and a fast-curing urethane coating is applied, allowing for a shortened construction period. - With a history in the waterproofing industry since 1945, the "composite waterproofing method" has approximately 40 years of experience and over 600,000 m² of construction achievements. - To ensure quality, we adopt a fully responsible construction approach by our in-house "craftsmen." - The amount of waste generated during renovations is minimal, and the materials used are almost all solvent-free, taking the environment into consideration. - By reducing the number of construction activities, we contribute to environmental conservation by decreasing CO2 emissions associated with production activities. *For more details, please refer to the PDF materials or feel free to contact us.*

Company information
Since our founding in 1945, Hamacast has been creating "good things" that no one can imitate. We develop and manufacture unique exterior materials and waterproofing materials, such as high-design stone-like exterior materials that replicate natural stone and excel in weather resistance and stain resistance, as well as tile exterior wall renovation methods that are highly safe and durable. We also offer waterproofing methods that combine over 40 years of experience and achievements in complex waterproofing techniques with added insulation and durability. Furthermore, our strength lies in our "complete responsibility construction," which ensures consistent quality and performance by managing all stages of construction and aftercare. By maximizing this strength, we respond to our customers' needs by enhancing the asset value of buildings and reducing maintenance and renovation costs. Moving forward, we will continue to explore without compromise to shape the values of a new era, consistently creating "good things" for people, communities, and the environment.
