Sealing and Plugging Material
Data Sheets
BAROID® BENTONITE PELLETS sealing and plugging material are compressed, shaped pellets of high-swelling, untreated sodium bentonite. BAROID BENTONITE PELLETS are available in three sizes: 1/4″, 3/8″, and 1/2″.
Applications and Functions
- Seal or grout plastic or steel casing
- Isolate screen intervals, subsurface instrumentation, and sampling zones
- Provide a protective interface between gravel pack and cement grout
- Plug abandoned earthen boreholes and cavities
- Create a stable, permanent, low permeability below-grade seal in:
- monitor/observation wells
- dewatering holes
- caisson holes
- soil sampling holes
- mineral exploration holes
- water wells
Advantages
- High swelling capacity in the presence of fresh water
- No heat of hydration
- Re-hydratable
- After hydration, forms a semi-solid, flexible seal with permeability less than 1 x 10-8 cm/sec
- NSF/ANSI standard 60 certified
