Mikolit B

Mikolit® B is an effective sealing pellet which requires no mixing or pumping. It can be used across various applications from borehole sealing to isolating instrumentation and sampling zones. Because Mikolit pellets are clay based it means they have very little dust content.

Mikolit® B is a high grade bentonite pellet manufactured from a mix of activated calcium bentonites to provide a high swelling capacity of 180-200%

The pellets have excellent sinking qualities and are simple and easy to use.
