Jointex

Jointex is a lightweight, cross-linked, closed cell, expanded Polyethylene joint former with a hinged temporary blocking piece. It has particularly good compression qualities with remarkable recovery capacity and is chemical and water resistant. Glue Jointex onto concrete face and cast next section of concrete. A neat and even joint will be formed. Doesn’t need bond breaking strip and is compatible with silicone.

Jointex is supplied with a hinged temporary blocking piece, leaving a clean, neat and perfectly sized groove providing a consistent depth channel for joint sealant. It can also  be supplied cut to size, eliminating wastage and cutting on site. Jointex is supplied with removable tear-off strip to ensure an even groove of uniform depth for filling with joint sealant.
