CALIBRATION HOSES

Calibration hoses for introduction of liners

The Calibration hose is used for rehabilitation jobs in non-accessible sewer networks. The calibration hose can be used for several jobs.

The Calibration hose is a non extensible and reinforced hose that can be put in a manhole to avoid liner from expanding during relining process.

The Calibration hose is used during liner pulling (double liner method), when the liner must be inserted till a non-accessible point. A first liner (not closed at both ends) is inserted and positioned in the sewer. Then the Calibration hose (closed at one end) is inserted into the liner and inflated so to tightly fix the liner to the pipe. This method is particularly useful to reline pipes when house connections are not accessible via a manhole.

There are several Calibration hose according to your jobs.
