Survey, rehabilitation, anti-corrosion, dredging, and repair — delivered as one integrated service. We support invisible sewer infrastructure with data and construction expertise.
Current-condition diagnosis via CCTV and visual inspection. We document the rationale behind construction decisions with data and records.
Construction technology that restores existing pipe function without excavation. Upgrade durability without halting city operations.
Coating and lining works that protect pipe surfaces from corrosion. Core technology supporting service-life extension.
Remove accumulated sediment and sludge from pipes to restore flow capacity. Performed with high-pressure jet trucks.
Localized function-recovery works including partial repair and water sealing. Minimum intervention, maximum function maintenance.
Work types, fleet, service area, and documentation — an integrated operations setup that supports field quality as one whole. Built to work alongside the prime contractors who handle sewer infrastructure.
From survey through construction (rehabilitation, anti-corrosion, dredging, repair) — the principal work types of sewer infrastructure, delivered as one.
From our bases in Aichi and Hokkaido, we serve projects nationwide according to scope, schedule, and team composition.
Completion documents, photo logs, reports, and construction-management documents (stage verification, daily work reports, safety documents) — field and paperwork handled in one stop. We reduce the administrative burden on prime contractors with the same precision as our construction quality.
Camera truck, inspection monitor, manhole work, jet washing, rehabilitation, and team. At every North site, we deliver reliable construction and detailed records day after day, to support the unseen infrastructure beneath our cities.
For early-career hires, for women, for newcomers.
From the field to management. At a company with a clear career path across technique × digital × education.
