SHARE
The twin hose is used for injecting grouting or any other strengthening product through a packer. One of the pipes is for inflation, the other for grouting. The grouting hose is available in 2 sizes: ½’’ et ¾’’ (Other diameters upon request). The inflation hose is in both cases, a Rilsan 3 x 6 mm hose. An extra length of the inflation hose allows it to be easily connected to the packer’s end and to the inflation pump.
