Industry & Occupation
Classification
Summary
Specialist who installs waterproof sheets on rooftops and balconies of buildings and houses to prevent rainwater infiltration.
Description
Sheet waterproofing workers install synthetic resin or vinyl chloride waterproof sheets on flat or sloped rooftops, balconies, terraces, etc. They perform substrate preparation, cleaning, and primer application on the installation surface, cut and position the sheets to fit dimensions, and then weld seams using adhesives or heat fusion. They also handle sealing around drainage drains and upstands to ensure the continuity of the waterproof layer. The work often involves high-altitude and outdoor environments, making it essential to secure a safe work environment using work scaffolds and safety harnesses. Demand is high not only in new construction but also in renovation projects, and skilled workers can advance to foreman or construction supervisor roles based on their proficiency.
Future Outlook
Stable demand is anticipated in both new building construction and renovation projects. While skill succession is a challenge due to the aging of craftsmen and shortage of young talent, the importance of specialized techniques is increasing with the introduction of environmentally considerate materials and the普及 of industrialized construction methods.
