VIP-Polymers Ltd's Cast-in gaskets (also known as anchored gaskets or cast in situ gaskets) are integrated with the segment during the casting process.
This is opposed to being glued into a pre-made groove once the concrete segments have been cast.
Cast-in seals ‘anchor’ themselves to the segment as the concrete surrounds the legs at the base of the seal. This process ensures a consistent positioning of the gasket around the segment.
The design of the legs ensures that the seal is secure in the segment and will not move during or after the segment is cast. This is especially important during installation of the tunnel segments.
Benefits of Cast-in gaskets include:
• No need to apply adhesive
• Cleaner to work with
• Provide cost savings due to the removal of adhesive and the gluing process.
• A more secure fit in the segment leading to reduced movement of the seal during installation and increased performance
