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.
