日本バンデックス List of Products and Services

"Vandex(R)" is a waterproofing agent that is directly applied to concrete structures. It complies with the Japan Architectural Standards Association JASS-8M301 standard. Its deep penetration effect helps prevent the neutralization of concrete and the corrosion of steel materials. Additionally, it forms crystalline calcium silicate within the capillary structure of the concrete, providing waterproofing to the concrete structure itself, allowing it to withstand water pressure that cannot be compared to other methods. 【Features】 ■ Densifies concrete and exhibits perfect waterproofing effect ■ Can be applied from either the inside or outside for waterproofing ■ Non-toxic and safe, with excellent workability ■ Certified with "ISO9001" *For more details, please download the PDF or feel free to contact us.

• Coating film waterproofing material/permeable waterproofing material

The "Vandex Flexin" method is a technique that involves injecting a very low-viscosity acrylic-based two-component synthetic resin into the leaking parts of concrete using a high-pressure injection machine. Holes are drilled at an angle of approximately 45 degrees into the leaking areas of the concrete, and a special nozzle is used to inject a hydrophilic injection material in a regulated amount, allowing it to fill the entire gap. The injected material becomes a highly elastic resin, demonstrating top-level water-stopping effectiveness. 【Features】 ■ The injected polymer is a durable and elastic hydrophilic high-elasticity resin. ■ The resin can absorb water and expand in volume under wet conditions. ■ The gel time, injection pressure, and injection duration of the injection material can be freely controlled. ■ A method capable of addressing various leakage phenomena. *For more details, please download the PDF or feel free to contact us.

"Vandex BB75E" is a two-component polymer-cement waterproofing material composed of BB75 (powder), which consists of cement, uniquely arranged aggregate particles, and special chemical components, and PK75 (liquid), which is an acrylic copolymer emulsion. The formed coating is rich in elasticity and has the ability to follow and resist cracking. Additionally, the created waterproof layer protects concrete and blocks from moisture and humidity, demonstrating excellent waterproofing properties. 【Features】 ■ Can be applied on damp substrates ■ Excellent elasticity, providing resistance to cracking ■ Possesses both waterproofing and vapor permeability ■ Safe to use with cement-based materials, making safety management easy ■ Dedicated reinforcement materials are available for joints and cracks, etc. *For more details, please download the PDF or feel free to contact us.

• Coating film waterproofing material/permeable waterproofing material

The "Bandex BZ System" is an innovative composite coating corrosion protection method that possesses resistance to sulfates and waterproofing properties. The method of mixing and applying BB75Z and PK75 (BZ-B method) excels in elasticity and has the ability to follow cracks. 【Features】 ■ Construction is possible even when the substrate is wet, making it suitable for new installations as well as repair and renovation work. ■ The reduced number of coating processes allows for a shorter construction period. ■ By using a topcoat that is compatible with organic acids, it can be applied not only to sewer facilities but also to kitchen drainage tanks and other areas. *For more details, please download the PDF or feel free to contact us.

• Coating film waterproofing material/permeable waterproofing material

The "Vandex EZ System" excels in the durability and protection of concrete and is a concrete anti-corrosion method that complies with the quality standards of the "Manual for Corrosion Suppression Technology and Anti-Corrosion Technology for Sewer Concrete Structures." It maximizes the adhesive properties of epoxy resin to the substrate, demonstrating stable adhesion over the long term. 【Characteristics of Epoxy Resin】 - Uses epoxy resin with excellent water resistance and chemical resistance, resulting in high mechanical properties of the cured material and outstanding durability. - Depending on the method, it excels in resistance to organic acids, preventing corrosion of concrete from organic acids generated in facilities such as building pits. - Has stable curing characteristics with minimal shrinkage during curing. *For more details, please download the PDF or feel free to contact us.

• Anti-rot, anti-termite, anti-mold material

The "Vandex WS System" excels in the durability and protection of concrete, possesses high safety standards, and is a concrete anti-corrosion method suitable for drinking water and other potable water applications, compliant with the Japan Water Works Association standard JWWA K 143 for "solvent-free epoxy resin coatings for the inner surfaces of concrete water tanks." Since it is a solvent-free epoxy resin coating, it does not contain solvents, eliminating the risk of solvent poisoning, and there is almost no shrinkage after curing. 【Features】 ■ Complies with Japan Water Works Association standard K 143 ■ Safe to handle ■ Excellent filling properties for pinholes in concrete substrates and workability with trowels ■ Superior mechanical strength after curing ■ Excellent water resistance and chemical resistance after curing *For more details, please download the PDF or feel free to contact us.

• Anti-rot, anti-termite, anti-mold material

"Bandestop 50" is a hydrophobic one-component polyurethane resin developed for stopping water leaks. For major leaks, please consider the higher-grade acrylic-based two-component synthetic resin "Bandex Flexin." 【Features】 ■ Can be used safely without solvents ■ Low viscosity for excellent workability ■ Immediately foams upon contact with moisture, providing a sealing effect ■ Complies with Ministry of Health, Labour and Welfare Notification No. 45 "Tests on the Materials of Equipment and Supplies" *For more details, please download the PDF or feel free to contact us.
