CTS-Anchored The CTS-Anchored seal is an integrated solution being directly cast-in to the concrete tunnel segment. In laboratory testing it delivers a similar water-tightness performance as the glued-in CTS Standard seals. Under the rough circumstances encountered in practical application the CTS-Anchored seal helps reducing the risk of leakages resulting from improper workmanship involved with the gasket installation & gluing procedure. Compared to the conventional glued-on seal the anchored seal provides a fivefold stronger bonding to the concrete and the risk of water penetrating underneath the gasket is decisively reduced due to the form-closed double barriers created by the two anchoring feet. With these improve- ments concerning sealing performance and security the CTS-Anchored seal offers decisive economic and environ- mental advantages with regard to the processes in the segment production plant. The advantages Saving of gluing procedure, purchase and storage of all materials needed for gluing. (Adhesives, spray guns, pressing frames, hazardous goods store, etc.) No pollution by solvents and therefore no health and safety measures including ventilation systems, etc. required No costs for recycling of used adhesive tins Reduction of process times for the gasket frame installation procedure by more than 60% No pre-working measures such as gasket groove repair required on segments before gasket frame installation. All CTS-Anchored seals are supplied as ready corner- vulcanized and project specifically tailor-made gasket frames. The profile geometry and also the procedures used for the project-related water-proofing performance and load-deflection behavior testing follow the recom- mendations of recognized institutions such as, e.g.: STUVA (GER), AFTES (F), and BTS (UK). The gasket installation The CTS-Anchored seal is directly clipped into a specially designed gasket groove machined in the inner face of the tunnel segment casting mold. The tunnel segment installation To obtain a proper seal, care must be taken to insure the gaskets are not damaged during installation. For the insertion of the key stone segment CTS recom- mends using the CTS-Teco-Lube on the gasket frames. The material The CTS-Anchored seals are made of a high quality EPDM- compound that meets the material requisition recommended by STUVA. In case of special requirements concerning chemical resistance when used in extremely contaminated ground CTS offers alternative materials ( e.g. CR/SBR elastomer for better resistance against hydrocarbons found in ground water ). This alternative material can be offered as a reasonable compromise, but always under consideration of lowering the typical and physical properties of an EPDM-compound with regard to aging performance and longevity.
