Description
Fast-curing, swellable, single-component, polymeric adhesive sealant. The special composition of HydroTank 306 Swell Mastic makes the sealant swell when in contact with water (to about 200% of original size).
Key Benefits
- Very high resistance to water pressure.
- Delayed swelling – will not swell during the installation process or during the concrete cure.
- Swells up to 200% of its original size to quickly seal leaks at joints in the structure.
- Very resistant to the high alkalinity of concrete.
- Maintains very high elasticity and tensile strength, even when swollen.
- Age resistant, no embrittlement.
