FOAMBAG™

FOAMBAG™

Details

Some four decades ago, we developed a low-cost flow stopping system called FOAMBAG™, based on the use of expanding resin foam. This effective yet simple technique works on all types of pipe material including cast iron, steel and PE. FOAMBAG™ is extremely versatile and can be used on vertical or tapering pipes, bends and non-standard diameters.

The major advantage of using FOAMBAG™ over conventional flow stopping bags is that far less pipe needs to be exposed resulting in considerably smaller excavations and reduced reinstatement costs. FOAMBAG™ has become an industry standard technique in the UK and has been used in many areas overseas including mainland Europe, the USA, Scandinavia and the Far East.

The technique works by inserting a semi-porous bag into the pipe to hold the foam in place as it expands. At full expansion, some of the foam seeps through the semi-porous material to adhere to the pipe wall.

Although developed for flow stopping natural gas pipes, FOAMBAG™ can also be used to seal pipes carrying other gases and fluids.
