New technology that takes into account both the environment and work vehicles!
Our company offers the "Water Jet Method," which enables surface cleaning of concrete, roughening, chipping, and the removal of various types of paint using ultra-high-pressure water jets. We do not use chemicals or abrasives, and since we utilize ultra-high-pressure water flow, we are also considerate of the environment. The pressure can be adjusted appropriately according to the type and condition of the substrate. Please feel free to contact us if you have any requests. 【Features】 ■ Can be performed without damaging the main body more than necessary ■ Can remove only the paint and deteriorated areas of concrete ■ Can strip paint and lining materials without damaging the substrate ■ Generates little dust, ensuring a considerate working environment ■ Compact design allows for a wide range of application conditions *For more details, please download the PDF or feel free to contact us.

Company information
In our country, during the period of rapid economic growth, approximately 10 billion cubic meters of concrete structures were built, many of which have experienced deterioration over time, leading to repair work being carried out in various locations. However, Japan has a strong concept of "scrap and build," and the technology related to repair and reinforcement is somewhat lagging compared to overseas. Therefore, Oba Construction Co., Ltd.'s Environmental Civil Engineering Division has started as a specialized department for the repair of concrete structures, aiming for high-quality repairs by actively introducing new technologies and overseas techniques. As a new technology for crack repair, we have adopted the "pressure-controlled injection method." By applying appropriate pressure with a pump while permeating the repair material, it ensures that the material reaches deep into the cracks. It can accommodate widths of up to 0.02 mm. Additionally, we own a German-made ultra-high-pressure water jet machine, which achieves high-quality surface treatment, chipping, coating removal, and cleaning compared to existing methods.
