We are delighted to announce our partnership with Obduramus Umwelttechnik GmbH and look forward to working together to distribute their exciting range of remotely installed NO-DIG repair seals throughout the UK, Ireland, UAE and Australia – VIP-WECO Remote.
The Obduramus range of internal repair seals are designed to fit pipes ranging from 150mm to 800mm in diameter and are suitable for all pipe materials. These seals can be installed remotely using inflatable packers and are designed and tested for repairing pipelines with operating pressures of up to 16 bar. Also available as end-liner seals, these can be installed in minutes and are offered as a permanent, maintenance free repair.
Jim Shaw, Sales Director at VIP-Polymers explained, “the Obduramus range compliments our existing VIP-WECO man-entry installed NO-DIG sealing system perfectly. It’s a very exciting innovation within the Trenchless Technology marketplace and will dramatically reduce the cost and time taken to repair smaller diameter buried pipes”
VIP-Polymers will market the Obduramus range as their VIP-WECO “REMOTE”brand and will be arranging demonstration visits at various water industry open and innovation days within the coming months. The range sits alongside the existing VIP-WECO WRAS approved range of man-entry installed internal pipe seals and also the DWI Regulation 31(4)a compliant VIP-WECO “PROLINE” internal pipe sealing system which has been used on several high-profile UK potable water projects.
VIP-Polymers, Business Development Director Luke Nethercot and Production Director Mick Gilchrist were recently invited over to Pandrol’s inaugural Global Supplier Forum in France.
The event was a real eye opener with conversations around sustainability and innovation, which lead to some interesting ideas being bought back to the office for discussion.
As a company we were extremely proud to have had all our hard work noticed by Pandrol with the presentation of a Global Supplier Award.
Many thanks to the Pandrol team for such an incredible event and experience and we look forward to taking the ideas and discussions raised and implementing them going forward.

VIP-Polymers – Will be exhibiting at the BTS Conference 2024
VIP-Polymers are delighted to be exhibiting at the BTS Conference and Exhibition 2024 on the 8th – 9th October at the QEII Conference Centre in London.
Luke Nethercote – VIP’s Business Development Director and Tunnelling Specialist will be at the event on Stand B68, with our latest Tunnel Segment Gaskets, including 2 new profiles launching this year and being shown for the first time at the show.
VIP’s tunnel segment gaskets are manufactured from high-grade rubber compounds, which meet many internationally recognised standards including EN681-1 (the material requirements standard for pipe and joint seals used in water and drainage applications).
Elastomeric (rubber) gaskets are one of the most effective waterproofing systems for segmentally lined tunnels and shafts where protection is required against water ingress or for retention in tunnels used for fluid transport or storage.
Each profile manufactured by VIP has been specifically designed so that the volume of rubber does not exceed that of its corresponding groove and the compression performance of the gasket is equal along the entire face of the gasket.
VIP offers a range of tunnel segment gasket profiles to suit various applications and specifications. In addition, our team of technical engineers have the experience and detailed knowledge to design bespoke gaskets for unique conditions.
Our dedicated test facility allows us to simulate the segment assembly, build conditions and sealing pressures as specified by the design. You can learn more about our range here.

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
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
UNIQUE CORNER JOINTING SYSTEM
No Solid Corners
Cracked or damaged segments caused by corner point loading has traditionally been a problem faced by tunnelling engineers and designers.
VIP’s Cast-in gaskets are designed specifically to eliminate this due to the unique patented (GB2541978 – international patent pending) corner jointing system.
This has allowed us to dramatically reduce the volume of rubber at the corners, thus ensuring the gasket can collapse into the groove.
MINIMISING RUBBER VOLUME AT THE CORNER JOINT
VIP’s unique jointing process results in the profile of the gasket being maintained up to the corner edge.
This differs to a traditional shot-joint corner which can result in excess rubber travelling along the gasket voids during the moulding process.
This results in making the gasket unable to compress at the corners due to the voids being full of rubber, creating a ‘solid’ corner.
The energy exerted at these points during closure of the segments can lead to cracks and spalling as it dissipates through the segment, finding the path of least resistance.
CORNER ANGLES THAT PERFECTLY MATCH THE SEGMENT
VIP can manufacture corners for cast-in gaskets to obtuse, acute and 90° angles, therefore matching the profile of the segment design perfectly.
90° Angles
Acute Angles
Obtuse Angles
Z Axis Angles
Segment design can differ with each project. Recognising this and the importance of the gasket matching the exact shape of the segment, VIP can also vary the profile orientation along the Z axis.
The following profiles comprise VIP’s cast-in core range.
Further profiles are available or can be developed on request to meet specific design requirements.
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.
VIP’s tunnel segment gaskets are manufactured in our Cambridgeshire headquarters in the UK, which is certified by The British Standards Institute to ISO 9001, using the latest manufacturing equipment and processes.
TSG RUBBER COMPOUND
VIP compounds its own rubber at our on-site mixing facility to proven formulations developed by VIP’s rubber technologists. The compounds used meet WRAS and other internationally recognised standards where required.
Predominantly EPDM is the rubber of choice for tunnel segment gaskets as it provides the sealing and material qualities required. However in instances where resistance to more aggressive chemicals is required, VIP can compound and manufacture using NBR (Nitrile).
TSG LIFE EXPECTANCY
A study carried out by Loughborough University in the UK on behalf of VIP concludes that one of the major elements affecting the gaskets’ long term sealing ability is ‘Stress-Relaxation’. This is the measurement of the force that a compressed gasket exerts over time which is crucial to the sealing performance.
The research also revealed that with correctly formulated and processed rubber, as supplied by VIP, the life expectancy of our gaskets is in excess of 120 years.
EXTRUSION
To begin the manufacturing process, VIP’s gasket profiles are extruded through one of the most modern microwave curing lines. This manufacturing technique creates the profile length by forcing the rubber through a die prior to curing. This is then cut to lengths determined by the segment requirements.
TSG CORNER JOINTS
All VIP’s corner joints can be manufactured in obtuse, acute and 90° angles to perfectly fit with the corresponding segments.
Using the latest laser guided cutting technology enables virtually any joint angle to be achieved and their design ensures that the sealing properties and closure forces match the extruded gasket section.
TSG QUALITY INSPECTIONS
In order to ensure the final product meets the high standards set by VIP, physical checks are made by our quality team both during the manufacture process and on final completed gaskets against:
Profile Size – to ensure a consistent profile shape during the extrusion process
Joint Integrity – to check the strength of moulded joints
Geometric Requirements – to check the shape of the finished gasket meets the segment design requirements
