Construction
Safety is something you build, protect, and grow.
From disaster prevention to repair — facility safety as a whole.
Maintenance work (Hokkai Koumuten)
Waterproofing, rust prevention, and life-extension work. From elevator pit and rooftop waterproofing to exterior wall and leak repair, we protect the asset value of the building.
Waterproofing & sealing (Value Method)
Sealing elevator pits, rooftops, and basements.
Flame-retardant treatment (Miracle agent)
Flame-retardant treatment for interior materials and fabrics.
Rust & corrosion prevention
Rust prevention for steelwork and equipment.
Bridge maintenance
Inspection, repair, and life extension of bridges.
Buildings in Hokkaido deteriorate differently from those on Honshu
Water soaks in, freezes and expands, then thaws and lets more water in. Repeated many times over a winter, this forces the concrete apart from the inside. That is why a repair that only seals the surface tends to fail in the same place the following season. We work on the principle of stopping the path the water travels.
Work we handle
Elevator pit waterproofing
Stopping the source of standing water and preventing equipment failure.
Rooftop & balcony waterproofing
We choose the method after examining the substrate.
Exterior wall repair
Cracks, chips, and resealing of joints.
Leak repair
From finding the entry point to sealing it.
Rust & corrosion prevention
Treatment that stops rust advancing on steelwork, handrails, and equipment frames.
