Leakmaster

Leakmaster LV-Z, commonly known as Leakmaster, is a high-performance hydrophilic gun-grade polyurethane waterproof​ sealant designed for reliable and efficient waterproofing solution. This versatile product expands upon contact with water, creating a watertight seal for joints, gaps, and cracks in concrete and other materials, making it an ideal choice for waterproofing concrete structures. Once cured, Leakmaster demonstrates superior physical properties compared to conventional putty-type sealants, making it a trusted choice for long-term waterproofing applications.

Its user-friendly design allows for application using a traditional caulking gun, ensuring quick and easy installation. The sealant adheres to a wide range of materials, including concrete, metal, and glass, before swelling. Leakmaster’s hydrophilic properties enable it to expand up to twice its original volume upon water exposure, delivering a reliable seal in high-moisture environments. Available in 320ml, it is suitable for both interior and exterior use, meeting stringent waterproofing standards.

For enhanced durability and waterproofing performance, choose Leakmaster, a leading waterproof sealant in hydrophilic waterstop solutions. We also offer Hydrotite, a hydrophilic rubber waterstop best used in joints.
