Description:
This granular bentonite is the most versatile size of bentonite. Often referred to as kitty-litter bentonite because of its similarities in size. This bentonite is most often used for setting vapor probes and back-filling wells but can be used in many other applications including building and repairing ponds.
CETCO CRUMBLES sealing and plugging agent is a granular bentonite product composed of polymer-free, dried bentonite in 8-20 mesh size. Derived from natural Wyoming sodium bentonite, Crumbles can be used for sealing and grouting well casings and earthen structures. CETCO CRUMBLES are certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals -Health Effects.
Recommended Uses:
May be used as casing seal, hole abandonment material, and for
sealing earthen structures.
Other uses include Pond construction repair in shallow ponds. Can be used to stop leaking ponds when poured from the surface. Bentonite hydrates to 3x original size and fills in cracks and crevasses, sealing up the leaks and stop excessive water seepage. Bentonite Crumbles can also be applied in 1 - 2 pounds per square foot surface at the pond bottom (more in areas over 1 foot deep). This layer is then covered in several inches of soil. Once hydrated, the bentonite layer creates a protective barrier preventing seepage.
Characteristics:
• Less than 10% moisture
• Provide a positive seal
• Re-hydrates
• Will not shrink or crack
