Penetration Sealing System

Product Documentation


HYDROPLUG is a unique tri-component system which consists of a polyester fibre reinforced polyurethane foam component, a hybrid putty component and a waterproof mortar component. The three components work together to provide an effective integral seal around surface penetrations, through concrete structures.


HYDROPLUG is used to prevent water ingress through service penetrations, ducts, conduits and cable transits. It is easily installed to provide an effective seal for the lifetime of the structure.
