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.
