Bulk (Palletized) Bentonite Clay – Pond Leak Sinking Sealant - FLAT RATE FREIGHT

Also available by the single bags for smaller applications 

Save 35% per bag - Fix pond leaks fast—before they get worse.

Palletized Bentonite reduces your cost per bag by 35%. Most pond owners first notice dam seepage in late summer or early fall, especially after droughts or heavy rain. That’s when cracks open up—and leaks appear. This granular bentonite sinks directly to the bottom, swells on contact, and seals soil fast without draining your pond.

Why It Works:

• Granular, not powdered – sinks and stays put
• Swells on contact – fills cracks, gaps, and pores
• No synthetic liner or excavation needed

Save when you buy bulk:

• 40x 50lb Bags – 2000lb pallet

How Much to Use:

• 3” layer = 18 lbs/sq ft (heavy leaks)
• 2” layer = 12 lbs/sq ft (moderate)
• 1” layer =  6 lbs/sq ft (light/preventative)

Dam leaks? Broadcast a 20-ft-wide strip (10 ft each side of the seep) from waterline to bottom.

Example: 8 ft deep × 22 ft wide = 176 sq ft

• 3” layer = 22 bags
• 2” layer = 14 bags
• 1” layer = 7 bags

Stock is limited during peak season. Order now—bentonite ships fresh and sells out fast.

Note: Pallets are typically shipped freight by motor carrier (semi).  Newalla Fish Company reserves the right to deliver your order directly if it improves survival or timing. We won’t refund shipping fees on orders delivered by our team — in fact, it often costs us more than standard shipping, but we do it to ensure the best results.
