New technology that takes into consideration both the environment and work vehicles!
Our company offers the "Water Jet Method," which allows for surface cleaning of concrete, roughening, chipping, and the removal of various types of paint using ultra-high-pressure water jets. This method does not use chemicals or abrasives, making it environmentally friendly. It can also be adjusted to the appropriate pressure 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 selectively remove only the deteriorated paint and concrete ■ Allows for the removal of paint and lining materials without damaging the substrate ■ Generates minimal dust, considering the working environment ■ Compact design accommodates a wide range of construction 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 of domestic concrete structures by actively introducing new technologies and overseas techniques. As a new technology for crack repair, we have adopted the "pressure-adjusted injection method." By applying appropriate pressure with a pump while permeating the repair material, the material reliably reaches the depths of the cracks, and it can accommodate widths of up to 0.02 mm. Additionally, we own a German-made ultra-high-pressure water jet machine, which enables high-quality surface treatment, chipping, coating removal, and cleaning compared to existing methods.
