The possibility of using materials capable of swelling with water, contained in extrudable cartridges, has recently expanded the usual application spaces in the field of waterproofing. Holes, cavities, slits, connections, tube passages, formwork spacers, represent the current ambit of the Azichem range of hydro-expansive sealants.
FLEXSEAL 300 is a sealant with high expansion capacity, suitable for reaching the most difficult points to waterproof with waterstops applied by nailing. FLEXSEAL 300 is also an important laying accessory for waterstop profiles, both traditional and hydro-expansive.
Flexseal 300
A hydro-expansive polyurethane sealant in a thixotropic paste, pre-packaged in an extrudable cartridge with standard dosing guns, to be utilised as a waterstop in the most complex or problematic situations in waterproofing below-ground areas. Its elastic and sealing properties remain unchanged over time. In a completely dry state, Flexseal 300 shrinks to its original size and then expands again upon contact with water.
