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 However, many bridges continue to be used under outdated design standards.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.

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.
