BAROID HOLEPLUG® is a naturally occurring Wyoming sodium bentonite clay supplied as 3/8" sized and graded chips for sealing and plugging earthen boreholes. Its high swelling potential allows it to expand in place, helping prevent surface water entry and vertical fluid movement while providing casing stabilization. The 3/8" chips are sized to pass through a 3/8" screen and be retained on a 1/4" screen, making them suitable for a range of well and drilling applications. HOLEPLUG® is ready to use without mixing.
