Ton pellets for annular space / borehole sealing: vacuum-extruded, swellable, high sinking speed, delayed swelling onset, free from organic additives. With Compactonit®, the Stephan Schmidt Group produces high-quality pellets and granulates according to DIN 4904 for the annular space sealing of well drillings and for the backfilling of boreholes. The cylindrical Compactonit® Type S pellets are swellable, resistant to contaminated waters, chemically unchangeable, and microbiologically safe. Regular environmental tests by GGU and Kiwa confirm that Compactonit® Type S ensures an environmentally friendly sealing.
