Narulight Injection Method: Waterproof Layer Regeneration Method / Penetrating Injection Method
We do not use any substances prioritized by the Health Housing Research Association or substances for which the Ministry of Health, Labour and Welfare has established guideline values!
The "Waterproof Layer Restoration Method" does not simply involve applying sheets or waterproof membranes to leaking areas or filling cracks with resin. It involves injecting a material called Narulight into the gaps between the pressure concrete and the waterproof layer, as well as between the slab and the waterproof layer, effectively sealing off the pathways for water intrusion and leakage. Additionally, the "Through Injection Method" involves drilling through the walls or floor concrete of a basement and injecting Narulight from the outside of the building. Narulight utilizes external soil pressure and water pressure to form a waterproof membrane on the exterior. At the same time, Narulight fills the leaking cracks due to water pressure, completely stopping the leakage. 【Features (Waterproof Layer Restoration Method)】 ■ No industrial waste is generated ■ Complete water stoppage can be achieved with partial repairs ■ Work is completed in a very short period ■ There is almost no noise during work ■ It adheres to asphalt and urethane waterproofing ■ Low cost *For more details, please refer to the PDF document or feel free to contact us.

Company information
Naruse Chemical has been walking alongside Japan's economic growth after the first oil shock, primarily in the manufacturing and supply of waterproof adhesives for construction, based on its independently invented "Atactic Polypropylene Water-based Emulsion" (Patent No. 925268). However, after the collapse of the bubble economy, Naruse Chemical is also facing a time of transformation amid the rapidly changing political and economic structure of Japan. We are now striving to respond to the diversifying needs not only in the construction sector but also in various fields such as marine, greening, and environmental issues, while aiming to transform into a high-tech company. We are confident that the existence value of "Technology of Naruse Chemical" lies in our ability to supply products that meet the demands of society and contribute to it.
