New developed GRP jacking coupling is taking place as an alternative to steel joints which are used in trenchless applications. It provides unique solutions to corrosion issue of agressive soil environment where metal couplings have limit of service life under corrosion attack.
New composite jacking coupling has minimum 50 years of service life in similar and even higher conditions. Special designed full face rubber profile ensures leak tigthness by help of its GRP structure of body and fully comply with the performance requirements of ISO 25780 standard.
