Subcon offers an 80kg custom-designed grout bag for applications such as flying lead stabilisation, anti scour protection and free span correction in high current applications. These bags are watertight so that they can be placed on the pipe before being activated by the diver or ROV. Bags are activated by puncturing them with a knife, spike or the ROV manipulator. Twin waterproof bag liners are thermally sealed to ensure the cement remains dry until it has been placed on the flying lead, forming its final shape before activation.
