Specialized construction work essential to every building, centered on concrete core drilling and non-destructive testing — handled end to end in-house.
Diamond core drilling uses a diamond-tipped bit rotating at high speed to drill holes in concrete (ALC, ALC board, and siding board) for water supply, drainage, electrical, and telephone piping, as well as for removing partitions or creating new openings. Because we inject water during cutting, the process is low-noise, vibration-free, and produces no dust.
X-ray inspection is a technique for examining the interior of walls, floors, and other structures without damaging them. It is used mainly to confirm the position of rebar, piping, and voids inside concrete, helping ensure safety before work such as core drilling or chipping. Our vehicle is equipped with a dedicated darkroom for on-site film processing, so results are available on the spot. We use those results to plan accurate, safe construction.
RC radar scanning uses dedicated electromagnetic radar to non-destructively inspect rebar, cover thickness, and voids inside reinforced concrete. It is harmless to the human body, so inspections can be carried out even in occupied or powered facilities. It pinpoints position and depth with high accuracy, enabling a quick safety check before core drilling or anchor installation.
Anchor installation involves drilling holes into existing concrete and embedding bolts or fittings to secure structures. It is used in a wide range of applications, including mounting equipment and piping, installing machinery, and seismic reinforcement. Depending on the application, we use cast-in anchors set during concrete pouring or post-installed anchors (metal or adhesive type) set afterward. Because secure fastening is essential, we confirm quality with pull-out testing on post-installed anchors, ensuring precise and safe installation.
Concrete chipping uses dedicated machinery and tools to shave or partially demolish hard structures such as concrete, asphalt, and tile. It is carried out mainly in renovation, demolition, and equipment work to create openings for piping and wiring. We remove unwanted sections with accuracy and safety, keeping the impact on the surrounding area to a minimum.
Sleeve and insert installation places openings (sleeves) for piping and wiring, and embedded fittings (inserts) for securing equipment, at designated positions in a building's concrete structure before the concrete is poured.
Interior demolition removes existing ceiling, wall, and floor finishes, fixtures, and equipment as part of renovation or restoration work. Before starting, we check the demolition scope and the condition of existing fixtures, taking care not to damage the parts left in place or the structural frame. We enforce strict dust and noise control and safety management, and dispose of waste materials properly in accordance with the law.
Our staff bring excellent construction skills and know-how that shorten project timelines. With specialized techniques such as X-ray inspection, we combine proven technical skill with extensive field experience to deliver careful, detailed work.
By providing our own vehicles, staff, and equipment, we keep intermediary costs down. With a large network of partner contractors, we complete work quickly without changing your requested schedule — balancing quality and cost.
Beyond technical skill, we aim to be a company that delivers peace of mind — valuing the connections between people and with our customers. Guided by our commitment to safety, reliability, and care, we strive to be a trusted partner for everyone involved in construction.
Centered on general contractors and equipment companies,
we maintain long-term partnerships with leading firms
in the equipment industry.
