Flexseal 300

Polymeric, extrudable, hydro -expansive sealant in cartridge

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.
