Revitalize the waterproofing layer using asphalt waterproofing! Introducing a waterproofing layer renovation method that achieves the longevity of facilities.

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 ample potential for its continued use. 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.
