Protecting the world's infrastructure with rope access technology
Protecting the world's infrastructure with rope access technology
At Keystone Co., Ltd., we leverage our experience, knowledge, and expertise in drainage well inspection to conduct safe and efficient surveys using rope access techniques.
Even when ladders cannot be used due to corrosion, our technicians can freely move inside to inspect any area.
In addition, our self-developed AnaPro360 shaft wall development precision photography system accurately captures detailed data of wall surfaces.
Furthermore, we can quickly confirm shaft wall distortion and tilt using a simple survey method with plumb bobs.
Using our proprietary AnaPro360 High-Precision Shaft Wall Photography System, we capture detailed and accurate data of interior surfaces for analysis and reporting.
We provide well-organized, easy-to-understand reports with high visual and technical quality.
