Dansco Utilities can provide flow stopping services for either planned or emergency operations, covering a wide range of pressures, materials and diameters.  We can also advise on the most suitable technique for the customers’ requirements. 

Our Below 7bar Flow Stopping capability include the following;

Metallic and PE flowstopping, using the ALH systems (630mm diameter PE and 36” metallic).

Medium & Intermediate Pressure flowstopping using the TDW Shortstop ll on PE & metallic mains.

Squeeze off operations up to 500mm PE for both Low, Medium & Intermediate Pressure.

Our innovative flow stopping techniques offer additional benefits to the customer such as; reduced excavation sizes, thus reducing the amount of excavated and waste material, reduced amount of backfill required, smaller excavation foot print which minimises the effect on any working space restrictions such as street works and safer working conditions for operatives working in shallower excavations.
