Waterproof, reinforced, and insulated with a special three-layer resin. Introducing the SOSEI method backed by verification tests such as accelerated weather resistance tests and bending strength tests, featuring eight characteristics!
The "SOSEI Method" is a spray cover technique that applies a three-layer special resin to aging slate and metal roofs, creating various effects such as waterproofing, insulation, and reinforcement. Here, we introduce the eight characteristics supported by verification tests! ■ Durability (Accelerated Weather Resistance Test) ■ Adhesion (Adhesion Confirmation Test) ■ Compressive Strength (Bending Strength Test) ■ Insulation (Slate Roof Insulation Measurement) ■ Safety (Punching Test) ■ Insulation (Roof Fire Resistance Test) ■ Impact Resistance (Ball Drop Test) ■ Waterproofing (Completely Seamless Waterproofing) *For more details, please download the PDF or feel free to contact us.

basic information
<Characteristic Details> ■Durability No changes observed after 4000 hours (approximately equivalent to 10 years) in the accelerated weather resistance test using the "Xenon Lamp Method." ■Adhesion The tensile strength of slate aged 40 years significantly exceeds JIS standards. ■Compressive Strength When a rejuvenation method is applied to slate aged 55 years, the compressive strength increases by 16%. ■Insulation By using external insulation for the roof, it contributes to improving the workplace environment during summer. ■Safety Average load capacity of 140 kgf (maximum 174.6 kgf), which means it can withstand the weight of approximately two adults, preventing puncture. ■Fire Resistance Embers naturally extinguish after 20 minutes. In the event of an emergency, the roof will not spread flames. ■Impact Resistance No damage observed even after the 50th drop of a 1 kg steel ball. ■Waterproofing Seamlessly integrates the overlaps of slate, hook bolts, and ventilation joints to achieve complete waterproofing. *For more details, please download the PDF or feel free to contact us.

Company information
"In order to protect the quality of the manufacturing line and products, we want to extend the life of the aging factory roof without stopping the production line." The SOSEI business was born from such customer feedback. By combining paint technology and resin technology, our unique three-layer spraying restoration method particularly encapsulates aging slate roofs that contain asbestos and cannot be washed, providing effects such as "waterproofing," "insulation," "reinforcement," "soundproofing," and "condensation prevention," and has gained support from many customers due to its cost advantages. The SOSEI method operates under a complete construction system, focusing on quality and safety, and offers proposals for roof renovation to protect the production line and products.
