中央建材工業 List of Products and Services

Central Building Materials Industry Co., Ltd. is a company that conducts large-scale renovation work and waterproofing work for condominiums and buildings. The "Deterioration Diagnosis Check Sheet" allows for a simple assessment of deterioration levels (I to III) based on different construction methods, including "Asphalt Waterproofing Protection Method," "Exposed Asphalt Waterproofing Method," and "Sheet Waterproofing Method," as well as the external condition. Additionally, we provide reference materials such as "Waterproofing Deterioration Survey: Deterioration Levels and Assessment." 【Deterioration Diagnosis Check Sheet (Partial)】 ■ Asphalt Waterproofing Protection Method - No waterproofing work has been done for over 17 years - Weeds are growing around the drain (drainage channel) ■ Exposed Asphalt Waterproofing Method - No waterproofing work has been done for over 13 years - The waterproof layer is bulging and so on. *If you would like to view the check sheet, please feel free to download it or contact us.

"Styroguard EX" is a revolutionary exterior insulation material for rooftop walking surfaces. By simply laying it out on the roof, it provides excellent insulation and condensation prevention effects, making it possible to reduce heating and cooling costs. Additionally, by covering the waterproof layer exposed to harsh natural environments, it helps to prevent the deterioration of the waterproof layer and contributes to the longevity of the building. 【Features】 ■ Blocks intense summer solar heat and shuts out winter chill ■ Simple installation method that only requires tightening with special fittings ■ Excellent water resistance and weather resistance, protecting the waterproof layer and preventing deterioration ■ Prevents condensation that can lead to building damage, contributing to increased durability by preventing thermal stress ■ The surface material features a three-dimensional and beautiful embossed pattern (non-slip effect) *For more details, please request materials or view the PDF data available for download.

The "Gel-Fit Rope" is a waterproofing material for concrete joints that utilizes the water absorption and gelation properties of modified and refined bentonite. Not only does the water-absorbed Gel-Fit Rope swell and provide a packing effect for waterproofing, but the gel that expands from the mesh of the Gel-Fit Rope also moves along the waterway, closing gaps and voids through a self-sealing action (secondary waterproofing). It is ideal for waterproofing all concrete joint areas in underground structures in construction and civil engineering. 【Features】 ○ Reliable waterproofing ○ Durability ○ Does not require strict construction conditions ○ Very easy to work with ○ PAT. No. 2857961 For more details, please contact us or download the catalog.
