The waterproof layer regeneration method "Narlight Injection Method" is a technique that creates a waterproof membrane between the pressure layer and the slab concrete without removing the pressure layer. By injecting a special resin into the gaps between the pressure concrete and the waterproof layer, as well as between the slab and the waterproof layer, it blocks the pathways for water intrusion and cracks in the structure, thereby regenerating the deteriorated waterproof layer to a sound condition. The asphalt waterproof layer adopted during construction remains in good condition even after 30 years, and there is still plenty of potential for continued use in the future. Additionally, under the protective specifications of asphalt waterproofing, the injected special resin is shielded from UV rays and heat by the protective layer, allowing for long-term durability. The Narlight Injection Method addresses the above challenges, enabling a reduction in the frequency of lifetime renovations, a decrease in CO2 emissions, and a reduction in running costs. *For more details, please download the materials or contact us.

The "waterproof layer regeneration 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 overlay concrete and the waterproof layer, as well as between the slab and the waterproof layer, thereby blocking the pathways for water ingress and the leaking areas. Additionally, the "penetrating injection method" involves drilling through the walls or floor concrete of a basement and injecting Narulight from the exterior of the building. Narulight utilizes external soil pressure and water pressure to form a waterproof membrane on the outer surface. At the same time, Narulight fills the leaking cracks due to water pressure, completely sealing them. 【Features (Waterproof Layer Regeneration Method)】 ■ No industrial waste produced ■ Complete waterproofing through partial repairs ■ Work is completed in a very short period ■ Minimal noise during work ■ Bonds with asphalt and urethane waterproofing ■ Low cost *For more details, please refer to the PDF document or feel free to contact us.
