日新特殊建設 List of Products and Services

We would like to introduce our modified asphalt sheet, "Custom NT40." It features a heavy long-fiber non-woven fabric as the core material, which is impregnated and coated with a special asphalt. Compared to regular modified asphalt sheets, it significantly excels in tensile strength and elongation performance. Additionally, it demonstrates excellent properties across a wide temperature range, as well as superior adaptability to uneven substrates. 【Features】 ■ Fully asphalt-impregnated type ■ Heavy long-fiber non-woven fabric as the core material ■ Impregnated and coated with special asphalt ■ Significantly superior tensile strength and elongation performance compared to regular modified asphalt sheets ■ Exceptional puncture resistance and high water pressure resistance *For more details, please refer to the PDF document or feel free to contact us.

Our waterproof sheet construction technology does not limit the materials we can use. The general waterproofing method, known as the "synthetic resin waterproof sheet method," utilizes waterproof sheets from members of the Japan Waterproofing Association. Please feel free to contact us when you need our services. 【Types and classifications of synthetic resin waterproof sheets (partial)】 ■ Low elasticity type: vulcanized rubber, polyvinyl chloride resin, etc. ■ Medium elasticity type: thermoplastic polyurethane, low-density polyethylene, etc. ■ High elasticity type: high-density polyethylene, medium-density polyethylene ■ Fiber-reinforced type: fiber-reinforced vulcanized rubber, fiber-reinforced polyvinyl chloride resin, etc. *For more details, please refer to the PDF document or feel free to contact us.

The "PF System" is a double floor system that can be directly installed without damaging the waterproof layer applied on the roof. The finishing materials come in a variety of options, including concrete-based and wood-based, allowing for selection based on application and aesthetics. It enables easy and speedy installation, and the PF stand is made of a special polypropylene resin that offers excellent durability. Additionally, it is lighter than traditional methods, reducing the load on the building. 【Features】 ■ High design quality ■ Excellent workability ■ Outstanding durability ■ Reduced impact on buildings and the environment ■ Maintenance management *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The "Custom NT40" is a high-strength, high-elasticity modified asphalt sheet (full-layer asphalt impregnated type) made with a heavy long-fiber non-woven fabric as the core material, which is impregnated and coated with special asphalt. This highly durable sheet is born from a long history of asphalt waterproofing, and compared to standard rubber asphalt sheets, it significantly excels in tensile strength and elongation performance. 【Features】 ■ Excellent properties across a wide range from low to high temperatures ■ Extremely superior puncture resistance and high water pressure resistance ■ Excellent adaptability to uneven substrates *For more details, please refer to the PDF materials or feel free to contact us.
