Why Use Fill Foam to Close An Abandoned Mine Shaft or Opening in Pittsburgh, PA
Polyurethane foam (PUF) plugs are a more recent development for closing & sealing abandoned mine shafts which are inexpensive and easily installed in remote areas. The advantage to using Fill Foam to close your abandoned Pittsburgh mine shaft is that there is no heat during installation. On high volume applications where heat would be a concern for polyurethane, FillFoam is safer.
In some applications where material needs to be pumped long distances or depths FillFoam can flow as far as 500 ft or up to miles based on the density; where as, Polyurethanes ability to flow would be limited by the reaction time. It is a matter of using the right product to fit the specific project conditions and requirements. There are times that could be polyurethane foam, FillFoam or both.
