Registered in the Ministry of Land, Infrastructure, Transport and Tourism's "New Technology Information Provision System"! Design Comparison Target Technology
Dispalite is a concrete joint treatment agent and setting retarder that provides excellent uniformity and high-quality joint surfaces, ensuring safe and reliable results. The standard type "Dispalite CR" for horizontal joint treatment delays the setting of concrete by spraying the concentrated solution when the bleeding water has receded after concrete placement, allowing for efficient and effective joint treatment. Additionally, we offer Dispalite ER, which further extends the setting delay time, and Dispalite DV, designed for vertical concrete joints. 【Features】 ○ Uniformity → Achieves a high-quality joint surface that is uniform and free of inconsistencies. ○ Reliability → Significantly alleviates time constraints during work, enabling efficient and reliable joint treatment operations. ○ Safety → No adverse effects on concrete or reinforcing steel. ○ Former NETIS registration number: No. KK-990050-V certified as "Design Comparison Target Technology" (registration ended).

basic information
【Features】 ○ A stable treatment effect is achieved, including around rebar, and a uniform joint surface is obtained through surface washing with high-pressure water. ○ There is no concern for environmental pollution as it does not contain harmful substances. ○ Acquired construction technology certification from the Public Works Research Center (Certification No. 0221) (Civil engineering materials, products, technologies, and road maintenance technologies). 【Product Lineup】 [For Horizontal Joint Treatment - Spray Type] ○ Standard Type: Dispalite CR [NETIS Registered Product] A treatment agent for horizontal joints in general concrete. By applying it when the bleeding water from the concrete placement has receded, it effectively and efficiently delays setting and treats the joint. ○ Super Delay Type: Dispalite ER [NETIS Registered Product] Compared to CR, it allows for a longer time from application to joint treatment, and the depth of treatment after washing out is also increased. [For Vertical Joint Treatment - Coating Type] ○ Coating Type: Dispalite DV [NETIS Registered Product] A joint treatment agent and setting retarder developed for vertical joints in concrete. ● For more details, please contact us or download the catalog.

Company information
Nihon Jikkou is a core company of a comprehensive engineering group that contributes to society through the production and sale of various related materials, starting with concrete anti-corrosion construction. Japan is now entering an era of high prevalence of social infrastructure such as water supply and sewage systems, with a vast number of concrete facilities being stockpiled. However, as these facilities age and deteriorate, it has become an urgent issue to systematically and effectively implement repair and maintenance measures to sustain them in the future. Nihon Jikkou and its group companies address these challenges by proposing optimal deterioration prevention measures based on environmental factors and facility characteristics, along with excellent construction techniques, thereby meeting all maintenance and management needs for concrete structures.
