The injected material is the appropriate sealing component that, when pumped through the transport hose to cracks emerged at the day joints during concreting, fills it and prevents possible leaks or capillary creep of water. They are available as single-component, dual-component or multi-component resins, gels or cement suspensions.
Depending on the shape of the component to be sealed and the general task that the insulation is required to fulfil, one should select appropriate sealing material with the right chemical ingredients and mode of the hardening reaction.
As a result of many years of practical experience in the installation of injection hose systems, our specialist teams have faced very diverse challenges in finding the hose nozzles where the injected material should be introduced. Due to low effectiveness of such searches, it is possible to execute an injection of a concreted hose by boring through it and injecting resin through the injection nozzle.

The injection nozzle, the so-called 'packer', is used to execute repairs and block leaks of water from fractures and unprotected day joints through the execution of point injections. After making the relevant required openings at uninsulated spots, the nozzle must be placed in the opening, and subsequently the injection material needs to be pumped in after connecting the pump to the nipple. In exceptional situations (injection hose outflow concreted and blocked), the injection nozzles are used to transport the injection material to the injection hose by boring through their profile.
