Pellets/Chips

Bentonite Chips/Pellets are made of Premium high Swelling Natural Sodium Bentonite. These form a flexible, permanent, non-toxic seal where water flows and hydrostatic pressures are involved.

Sizes are available in 5 to 10 mm (1/4 to 3/8 inch) and any Bespoke solutions would be available.

Applications

• Seal all types of well sealing, abandonment, seismic shot holes, grounding rods, mineral exploration holes, etc.
• Seal surface casing for water wells and well pits.
• Provide an intermediate seal, preventing inter-aquifer transfer.
• Seal at the upper most aquifer and prevent entrance of surface water into aquifer.
• Seal abandoned wells maintaining aquifer yield and artesian head.
• Works under most conditions.

Features

• Increased hardness and density provide better settling characteristics. Can be placed in a dry or wet borehole with the same ease as pea gravel.
• Extremely slow swelling rate allow the proper placement of the Bentonite seal without bridging.
• Will swell up to 15 times its dry volume when hydrated by fresh water.
• It will provide an “in place” expansive seal.
• Cost effect.
• Superior characteristics where low permeability flexible seals are required.
• It will not shrink or crack with time.
• Non-toxic and non-polluting.
• Eliminates void and bridging.
