Mikolit 300

Mikolit® 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 300 is a medium grade bentonite pellet and has a swelling capacity of 50-70%. The pellets have excellent sinking qualities and are simple and easy to use.
