PUR-O-STOP FS-F
Extremely fast reacting, from rigid to tough elastic, 2K polyurethane resin, which foams up in contact with water
- For the sealing of highly pressurized water inflows with large volume flows, e.g. strong water inrush
- For sealing of highly water bearing areas in soil, gravel, concrete or behind steel sheet pilings
- For sealing and solidifying of soil and gravel
