Formwork
Services

Specialized concrete formwork for RC and SRC structures. We handle everything from standard wall forms to complex custom geometries — including large-scale redevelopment projects.

01
General Formwork

Standard concrete formwork for walls, columns, beams, and slabs. Precise assembly and safe execution on any scale including major urban redevelopment.

02
Foundation Work

Base slab and foundation formwork for RC structures. Strict alignment to design tolerances within ±3mm on complex multi-level basement construction.

03
System Formwork

Modular, reusable formwork systems for large or repetitive structures. Proven on some of Tokyo's largest commercial and mixed-use developments.

04
Architectural Concrete

Exposed finish (打ち放し) formwork with premium surface quality. Used in facilities where aesthetics and structural integrity both matter.
