Traditionally the industry has used elastomeric gaskets that are glued into pre-formed grooves in the concrete segments.

VIP manufactures a range of profiles which are compatible with many pre-existing segment mould groove designs.

The following profiles comprise VIP’s glued-in core range. Further profiles are available or can be developed on request to meet specific design requirements.

CORNER ANGLES THAT PERFECTLY MATCH THE SEGMENT

VIP’s glued-in profiles have corner joints that can be manufactured to match the angles of the segment design including 90°, acute and obtuse angles.

The corners are formed using an injection process in moulds that match the profile of the extruded gasket.

This ensures that when the segments are joined together, the gasket can collapse into the groove and the load on the corners is equal to the rest of the gasket.
