Aitec Corporation Business Introduction

Aitec Corporation Business Introduction

We will challenge the long-life extension of the life cycle cost of concrete structures.

Concrete structures were recognized until recent years as maintenance-free. However, as reported by the media in recent years, there have been numerous cases of structural damage caused by the corrosion of steel due to chloride ions and the neutralization of concrete. Additionally, concrete structures can be damaged by alkali-silica reactions, freeze-thaw cycles, and acid rain. Furthermore, due to societal demands for increased efficiency in road transportation, the design loads for road bridges have been increased since 1993. However, many bridges continue to be used under outdated design standards. These structures often lack sufficient load-bearing capacity, and many are experiencing damage due to overloading. The myth of concrete structures as maintenance-free permanent structures has become a thing of the past. At Aitec Co., Ltd., we challenge the long-life cycle of various concrete structures that support our daily lives with the latest repair and reinforcement technologies. For more details, please contact us or download our catalog.

Anti-corrosion coating and sheet lining method (prepreg post-application type) HKS method

Anti-corrosion coating and sheet lining method (prepreg post-application type) HKS method

Dramatically improve the quality of the sheet joint area.

▼Overview The HKS method is a corrosion protection coating technique applied to concrete exposed to harsh corrosive environments. In traditional post-laminated sheet lining methods using prepreg, the seams become laps, raising concerns that ultraviolet light may not adequately penetrate, resulting in incomplete curing. The seam treatment in the HKS method employs a revolutionary corrosion protection coating technique that uses molded joint materials made of high corrosion-resistant vinyl ester resin FRP for joint treatment. ▼Features This method involves applying HKS sheets to concrete surfaces or cross-section repair surfaces that have been coated with primer, followed by ultraviolet irradiation to achieve complete curing and integration with the concrete. The joints feature a double structure where FRP molded products are installed with a highly corrosion-resistant sealing material, providing excellent durability. Compared to traditional post-laminated sheet lining methods that involve overlapping sheets for joint treatment, this method offers superior workability. Additionally, it possesses sufficient corrosion resistance for the harsh corrosive environments found in sewer-related facilities.

FRP lining waterproofing method [Sewerage facilities]

FRP lining waterproofing method [Sewerage facilities]

The design emphasizes corrosion resistance, crack-following ability, and measures to suppress pinholes!

The concrete corrosion phenomenon in sewer facilities is known to occur due to the generation of sulfides by sulfate-reducing bacteria in sewage sludge. Hydrogen sulfide gas, which is released from the liquid phase to the gas phase, dissolves in condensate water and progresses due to sulfuric acid produced by sulfur-oxidizing bacteria. Even when coated with anti-corrosion materials, corrosion progresses from areas where pinholes or cracks have developed in the anti-corrosion material, leading to breakage or cracks that cannot follow the cracks. The "Airtight Construction Method" is designed with a focus on corrosion resistance, crack-following capability, and measures to suppress pinholes. In sewer facilities, we propose measures for reducing life cycle costs and extending service life based on the functions and performance that meet the required specifications and long-term durability records. 【Features】 ■ Maintains performance over a long period ■ Deterioration can be visually assessed, making repairs easy ■ Enhanced crack-following capability due to high strength and flexibility ■ High corrosion and chemical resistance, capable of handling special wastewater inflow *For more details, please refer to the PDF materials or feel free to contact us.
