Silicoflex Joint Sealing System

Installation of Silicoflex

The Silicoflex Joint Sealing System is an innovative system

developed by R.J. Watson in the mid 1990’s. It was designed in

response to the absence of a sealing system that was both easy to install and offered a long, effective sealing life. This absence has been filled with Silicoflex and its features have made it a popular alternative to traditional sealing systems throughout the world.


The Silicoflex System consists of an inverted ‘V’ shaped, preformed, extruded silicone rubber seal, with a single component silicone locking adhesive and a primer. Two

beads of silicone locking adhesive are used; one above and one below the silicone rubber seal to ensure a tenacious, water-tight and continuous seal.
