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.

The water stop agent "Narustop" provided by Naruse Chemical is a caulking type water stop agent for concrete joints. It adheres strongly to concrete and waterproofs and stops water at the concrete joint interface. The application is also easy, and it demonstrates excellent effectiveness in preventing water leakage accidents. ~ A free booklet that explains "foundation waterproofing" in detail is currently available! ~ For those considering the purchase of a new house or single-family home, we provide an easy-to-understand explanation of "foundation waterproofing." If you would like the booklet, please contact us and indicate "booklet request." * A manual for single-family foundation construction is also available for download in the catalog. * For more details, please download the catalog or contact us directly.

"Narustop" is a joint water stop agent that utilizes the adhesive properties and waterproofing of water-based asphalt emulsion. Since it does not use any organic solvents, it is non-toxic and non-flammable, allowing for seamless application. It does not expand, so it will not damage the concrete. 【Features】 ■ High-viscosity asphalt water-based emulsion ■ Can be applied to uneven surfaces (chipped surfaces), cast-in-place surfaces, and damp substrates ■ Strong adhesion to existing concrete and newly poured concrete ■ Easy and inexpensive to apply ■ Seamless application is possible *For more details, please refer to the PDF document or feel free to contact us.

The basic structure of the foundation for detached houses consists of a flat foundation with vertical concrete installed. The joints created during this process pose a risk of rainwater intrusion. This time, we will introduce a cartridge-type joint water stop agent that allows for easy, inexpensive, and reliable waterproofing.

"Naru Stop" is an economical and easy-to-use cartridge-type water-based asphalt joint sealing agent. Unlike traditional water stop board methods, it can be applied independently, significantly improving work efficiency. As a paste-type sealing material, it thoroughly penetrates the fine irregularities of existing concrete. 【Features】 ■ Long application distance per unit makes it economical ■ Can be used independently, greatly reducing construction time ■ Effectively guards against water intrusion through chemical reactions with concrete ■ Can be applied outside of rebar, providing expected rust prevention effects *For more details, please refer to the PDF materials or feel free to contact us. *The catalog is a digest version.

This document explains the waterproof layer regeneration method using Narulight injection (special resin injection method). This method involves pressing "Narulight" into the gaps above and below the waterproof layer to fill all the gaps with Narulight. It blocks all water entry points and regenerates the deteriorated waterproof layer to a healthy state. The document includes information on the components and features of Narulight, standard construction procedures, and guidelines for injection quantities. Please make use of it. [Contents (partial)] ■ Components of Narulight ■ Features of Narulight ■ What is the waterproof layer regeneration method? ■ Features of the waterproof layer regeneration method * For more details, please refer to the PDF document or feel free to contact us. * The catalog is a digest version.

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.
