"Vandex Q-80" is a cement-based water stop and repair filling material manufactured using a special ultra-fast hardening inorganic compound as its base material. The main component is Portland cement, which does not lead to a decrease in strength due to the transfer of hydration products, as seen in alumina cement-based materials. In addition to forming a high-strength hardened body in a short time, it also demonstrates stable strength and adhesion over the long term, with excellent adhesion strength to concrete and mortar. 【Features】 ■ Can be used simply by mixing with water ■ Forms a dense hardened body, exhibiting superior waterproofing and water resistance compared to ordinary concrete and mortar ■ Minimal shrinkage, cracking, and reduction in strength characteristics over time after application ■ Non-corrosive to metals such as rebar ■ Safe to work with as it does not contain harmful components, among others *For more details, please download the PDF or feel free to contact us.

The "Vandex Flexin" method is a technique that uses a machine to inject a very low-viscosity acrylic-based two-component synthetic resin into the leaking parts of concrete under high pressure. A hole is drilled at an angle of approximately 45 degrees into the leaking area of the concrete, and using a special nozzle, a hydrophilic injection material can be continuously pressed in at a specified 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.
