mason Posted: May 16, 2009 08:00 AM	I am not familiar with the "dry pack" but pour in place polyurethane foam has been used for years to close mines openings. There is a military specification on the foam type (physical properties) that the Department of the Interior developed. I would check with them first and with your suppliers.
