HydroTank 306 Swell Mastic is a single-component, water-reactive polymeric adhesive sealant designed to swell up to 200% upon contact with water, effectively sealing construction joints and service penetrations. It provides high resistance to water pressure and superior adhesion, making it a reliable solution for waterproofing applications.
Key Benefits:
✔ High Water Resistance – Withstands significant water pressure for superior waterproofing. ✔ Delayed Swelling – Won’t expand during installation or concrete curing, ensuring optimal performance. ✔ Self-Sealing & Flexible – Expands up to 200%, creating a tight, watertight barrier. ✔ Durable & Age-Resistant – Maintains high elasticity and tensile strength, even when swollen. ✔ Highly Alkaline Resistant – Withstands the harsh chemical environment of concrete. ✔ Quick & Easy to Apply – No embrittlement over time, ensuring long-term performance.
Typical Applications:
✔ As a detailing product for HydroBond 403 Plus waterproofing system. ✔ Adhesive for Newton System 300 hydrophilic waterbars. ✔ Sealing service penetrations, such as pipes and conduits through the structure. ✔ Enhanced waterproofing around pipes sealed with Newton 307 PipeSeal.
