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

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

Absorbs water and expands instantly! Highly effective in deodorizing 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 capabilities. 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 does not experience 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.

Non-curing single-component water stop material Tame Taro® for construction and electrical equipment (NETIS)

Non-curing single-component water stop material Tame Taro® for construction and electrical equipment (NETIS)

Construction is possible even during flowing water! Handling of handhole water leaks and prevention of water leaks in structures.

In the construction industry, preemptive waterproofing measures are crucial to enhance the durability of buildings. Particularly in underground structures and buried pipelines, water leakage can accelerate the deterioration of structures and has the potential to lead to serious accidents. Additionally, flooding of electrical equipment can adversely affect critical electrical devices. The non-curing one-component water stop material, Metaro, adheres to resin, rubber, metal, concrete, and other materials, and can be applied even in flowing water environments. It prevents water leakage in handholes and cable penetration areas, thereby improving the integrity of the building. 【Usage Scenarios】 - Water leakage prevention from laid cables - Handhole water leakage treatment - Water leakage prevention from cable conduit materials - Gap leakage prevention around sleeves - Water leakage prevention from concrete cracks - Sealing and condensation prevention inside cubicles and panels 【Benefits of Implementation】 - Suppression of structural deterioration due to water leakage - Reduction of flooding risks for electrical equipment - Response during cable reinstallation - Long-term water stop effect - Prevention of rodent intrusion *For more details, please feel free to request the catalog directly via email or download it from the "EPJ Corporation" link on the "Ipros Special Site."

Non-woven fabric product example: Concrete joint water stop material

Non-woven fabric product example: Concrete joint water stop material

We have developed a component to stop water leakage at the concrete joint in construction materials.

We would like to introduce the "Concrete Joint Water Stop Material" developed by Sanadd Co., Ltd. This product is a construction material designed to stop water leakage at concrete joint areas. Not only does the bentonite granule inside the bag absorb water and swell to create a water stop, but the gel that swells from the mesh of the bag can also block gaps, providing two effects. [Reasons for using granules] - By using granules, the structure of the particles increases the swelling speed. - After filling with bentonite, if it were in powder form, the powder would leak out through the gaps in the bag, so we made it into granules to prevent this. *For more details, please refer to the related links or PDF materials, or feel free to contact us.
