Powder Sodium Bentonite in 3,000 lb Super Sacks for Sewage Lagoons, Ponds, and Earthen Liners

If you’ve ever built or rehabbed a sewage lagoon, lined an earthen basin, or fought seepage in a pond, you already know the job comes down to one thing: controlling permeability. That’s where powder sodium bentonite shines.

At A&A Equipment & Supply Co., we supply powder sodium bentonite in 3,000 lb super sacks for contractors who need a dependable, field-proven sealant for sewage lining, ponds, lagoons, and other water-control applications—without introducing harmful additives to the ground.

Bentonite is widely used because it’s a naturally occurring sealant, and suppliers note it’s non-toxic and designed to avoid compromising soil, groundwater, and nearby wildlife when applied as intended.

What is powder sodium bentonite and why contractors use it

Sodium bentonite is a natural clay used in “earthen sealing” because it creates a very low-permeability barrier when installed correctly. The material is commonly positioned as safe and additive-free—no harsh chemicals meant to “bind” or “cure” in the soil.

On real jobs, that translates into a simple value proposition:

• Reduce seepage

• Improve water retention

• Create an earthen liner without synthetic membranes

• Simplify long-term maintenance

Suppliers also highlight that bentonite is relatively cost-effective and available in packaged bags and bulk quantities—which is exactly why 3,000 lb supersacks are so popular for contractors.

Where 3,000 lb supersacks of powder bentonite are used

1) Sewage lagoons & wastewater lining

Bentonite is commonly used as a pond/lagoon sealant to help reduce infiltration and stabilize performance—especially when you’re building or rehabbing an earthen basin. Suppliers specifically position sodium bentonite as a preferred material for pond sealant applications.

Typical buyers: excavators, sitework crews, municipalities, and wastewater/lagoons operators.

2) Ponds and retention basins (new build or repair)

Suppliers describe “pond seal” bentonite as being used to rectify leaking ponds or prevent leaks in new ponds, and note it’s most effective when blended with soil or placed between two layers of soil along the pond bed.

That’s why contractors like powder formats for:

• Mixing into scarified subgrade

• Building a compacted liner layer

• Targeting problem areas during rehab

3) Earthen containment and sealing work

Beyond ponds/lagoons, suppliers list bentonite uses that involve sealing voids or holes where water control matters (wells, boreholes, casings).

Why 3,000 lb super sacks are the contractor-friendly format

For bigger jobs, packaging isn’t a detail—it’s the difference between a smooth install and chaos.

3,000 lb super sacks are used because they:

• Cut labor versus handling dozens of small bags

• Stage cleanly on site

• Handle easily with a forklift/telehandler

• Make it easier to plan material quantities and freight

Suppliers specifically note that full truckload orders are shipped on pallets in 3,000 lb super sack bags, which is why this format maps so well to lagoon and large pond work.

Powder vs. granular: when powder is the right call

Suppliers describe multiple bentonite product types and their typical use cases:

• Pond seal (crushed sodium bentonite): applied to pond bottoms or problem areas and is most effective when blended with soil or layered in the pond bed.

• Granular bentonite: commonly used for filling voids and sealing wells/boreholes; forms a gel-like substance when in contact with water.

• Bentonite grout (finely powdered bentonite): formulated for sealing abandoned drill holes, well casings, and geothermal holes.

If your customer is doing sewage lining, lagoon lining, or pond liner construction, powder bentonite tends to fit best when your method involves mixing and compacting a liner layer.

What to expect on pricing and budgeting (so you can quote jobs faster)

Bentonite cost depends on quantity, shipping/freight, and market demand, but suppliers publish planning guidelines such as:

• Truckload (22.5 tons): approx. $90–$100/ton + freight, shipped on pallets in 3,000 lb super sack bags 

• Mid-size projects: example pricing for 2,500 lb super sacks around $300/bag (as a guideline)

• Small projects: example 50 lb bag pricing around $8/bag (as a guideline)

For A&A customers, we typically quote based on:

• Job location (freight is often the swing factor)

• Total sacks/tonnage

• Your preferred delivery window and unloading capability

Logistics that matter to excavators and municipalities

A common pain point with sealing materials is delivery and handling. Suppliers emphasize flexibility such as:

• Ability to ship anywhere in the United States

• Ability to load bulk directly into a dump-type trailer

• Pickup options from a warehouse near Austin 

That “contractor logistics” mindset is how A&A approaches bentonite supply too: we aim to make the ordering, staging, and delivery cadence fit your schedule—not the other way around.

FAQs contractors ask before they order

Is sodium bentonite safe around soil and water? Suppliers state their bentonite products are natural and do not contain harmful chemicals or additives that could compromise soil or groundwater, and describe them as safe for humans, plants, and wildlife.

Does soil type matter? Yes. Suppliers note that “coarser and more porous” soil typically requires more bentonite to achieve a seal.

Can I use bentonite for new ponds and for repairs? Yes—suppliers describe pond seal bentonite as being used both to prevent leaks in new ponds and to fix existing leaking ponds.
