Water-stopping material "Water-Expandable Non-Woven Fabric"

It absorbs water and expands instantly! It has high deodorizing properties against ammonia and can be reused repeatedly by drying in the sun.

"Water-Expanding Non-Woven Fabric" is a waterproof material that incorporates high water-absorbent and high moisture-absorbing fibers into non-woven fabric (polyester fibers) to provide water absorption properties. It has approximately twice the moisture absorption capacity of silica gel and quickly absorbs water due to its large surface area. Even under pressure, it does not easily release water. Additionally, it has a high deodorizing effect against ammonia, can be reused through sun drying, and shows no significant performance degradation even after repeated water absorption and moisture absorption. [Features] ■ High water absorption ■ High moisture absorption ■ Flame retardant ■ Heat resistant ■ Reusable *For more details, please refer to the PDF document or feel free to contact us.

Water-stopping material "Kuniseal C-31"

Easy installation for shortened construction period! Bentonite concrete joint waterproofing material.

"Kuni Seal C-31" is a waterproofing material that is very easy to install, as it is wrapped in a water-soluble film on the surface. It can be applied simply by wetting it and placing it on the installation surface, pressing it down, without the need for special tasks like nailing. The bentonite particles that come into contact with water expand while following the fine gaps in the concrete, completely filling the water paths and allowing it to withstand high water pressure. Additionally, because the fine particles expand while releasing pressure, it does not generate large pressures that could crack the concrete. 【Features】 - Can be applied to all types of uneven surfaces - Characteristics that do not degrade in performance for semi-permanent use - No special surface treatment or caulking preparation required - Efficient end joints For more details, please contact us or download the catalog.

【NETIS Plus AC-170027-P】Bitograut-UG

Complete waterproofing under previously deemed impossible adverse conditions is now possible.

Our company employs the "Bitogrout-UG Injection Method," which completely seals leaks in underground structures and ensures long-term stability through the formation of external waterproofing. We drill a penetration hole in the back surface of the concrete structure and inject a water-based emulsion resin from there towards the inside. The resin permeates and backflows through various leak paths, forming a new waterproof layer. Additionally, this method allows for water stoppage over a long period of 10 to 25 years (with proven results), significantly reducing maintenance costs. 【Features】 ■ Enables water stoppage for a long period of 10 to 25 years (with proven results) ■ Low maintenance costs ■ Possesses stability performance that can be referred to as "post-construction external waterproofing" ■ Strong adhesion ensures long-lasting water stoppage effects ■ No volume reduction or permeability after curing *For more details, please refer to the PDF document or feel free to contact us.
