Granular Bentonite Pond Sealer – 3,000 LB Super Sack

WATER-FILLED POND APPLICATION

Target a Known Leak Without Draining the Pond

Granular, or crushed, sodium bentonite is intended for a very specific situation: your pond still contains water, draining it is impractical, and you have a reasonable idea where the seepage is occurring.

The granules can be distributed over the water above the suspected leak area. They sink toward the pond bottom, hydrate, swell, and may help reduce seepage through small cracks and porous soil.

CHOOSE THE RIGHT MATERIAL

Is Granular Bentonite the Right Fit?

Use Granular Bentonite When

• The pond currently contains water.
• The suspected leak or seepage zone is reasonably well identified.
• Draining the pond would be difficult or impractical.
• You need material that can sink through the water toward the target area.

Use Fine / Mix Mesh Instead When

• The pond is dry or can be drained.
• You are sealing the entire pond bottom.
• The bentonite can be mixed with native soil.
• The treated soil can be compacted into a continuous liner.

APPLICATION

How Granular Bentonite Is Used on a Pond With Water

This method is most useful when the treatment zone is limited. If the leak location is unknown, spreading material across the entire water surface can consume a large amount of bentonite without addressing the actual seepage path.

01

Identify the Area

Narrow the suspected seepage zone as much as practical before applying material.

02

Distribute Granules

Apply over the water above and around the target area. Equipment depends on access and pond size.

03

Let It Hydrate

The granular bentonite sinks, absorbs water, swells, and can migrate into small seepage paths.

04

Monitor Results

Track the water level. Broad or unidentified leaks may require additional treatment or a different method.

QUANTITY & PROJECT FIT

How Much Granular Bentonite Do You Need?

For a localized leak in a pond that still contains water, quantity should be based on the suspected treatment area and leak conditions, not automatically on the total square footage of the pond.

Send us the approximate pond size, water depth, suspected leak location, and ZIP code. We can help determine whether granular bentonite fits the situation and estimate material plus freight.

BEFORE YOU ORDER

Not Sure Granular Bentonite Fits Your Leak?

The right solution depends on whether the pond is dry or full, whether the leak is localized, soil conditions, access, and project size. Use the Pond Sealer Guide if you are not certain which method belongs in your pond.

What Customers Say About Lonestar

Bernard Johnson ★★★★★ Lonestar and Rick, Alex and Adan did an excellent job on my pond. They are the experts in pond construction, bentonite application and re-working older ponds. Adan did a great job surveying my pond and making sure everything met my expectations—he is very talented and a very hard worker. They have an extensive list of references and photos from their past projects. They were very helpful every step of the way with explanations and photos of what they were doing on my project. I highly recommend Lonestar. Thank you.Footbridge Foundation Animal Rescue ★★★★★ We had a wonderful experience working with LoneStar Minerals. Footbridge Foundation is a foster-based animal rescue, and we provide cat litter to all of our foster homes as well as the cats receiving care in our clinic.We go through litter incredibly quickly, and it can be a significant expense for a smaller nonprofit.When we recently ran out, LoneStar Minerals graciously stepped in and donated an incredible 5,000 pounds of bentonite cat litter to help us continue caring for the cats in our rescue.David and Arturo were both incredibly kind, knowledgeable, and helpful throughout the process. They took the time to answer our questions and make sure we had exactly what we needed.We’re incredibly grateful for their generosity and support of our mission. If you’re looking for bentonite or other mineral products, we highly recommend LoneStar Minerals.They’re an honest, knowledgeable company and wonderful people to work with.Mike Cavender ★★★★★ Carla and Rick did an outstanding job of walking me through the process of buying and receiving Pond sealer Bentinite out of their Bulverde Warehouse. The process was easy and went just like they said it would. I have now worked with them 2 times and the experience was exceptional, They do a very professional job all the way around from start to finish. I will look forward to working with them again in the future.Mike C.Catherine Raney ★★★★★ We had a great experience with Lone Star. From the first to the last, they were extremely professional. Ricardo patiently walked us through every step of the process and answered all of our questions thoroughly. Alex was very communicative and managed his crew very well.The crew were efficient and considerate of our property. The skill level of the tractor work was beyond compare with anything we have experienced previously. Adan is an absolute master Tractor operator! This is the third time we have had our pond worked on by different companies, and this was far and away the best experience. No comparison really between the other two companies and Lone Star. I cannot recommend them enough! This is our first (And last!) Time to use the sodium bentonite, and we are expecting excellent results. The pond is beautiful and perfectly shaped. Now we just need rain!Patrick Winn ★★★★★ 30 Super Sacks! Great product. Great service. Great delivery.Henry Boubel ★★★★★ Had a great friendly experience with Ricardo while sharing my situation with him he as well shared, his professionalism expertise on the matter regarding my septic tank.Noon Bio ★★★★★ Arturo and Ricardo are exceptional people that provide a great service. They were thorough and explaining how to apply it looking forward to doing further business.Ezequiel Arredondo ★★★★★ "I can't recommend them enough! Rick went above and beyond to help me and treated me with honesty, respect, and kindness from start to finish. They even did me a huge favor that they didn't have to do, and I truly appreciate it. It's hard to find people who genuinely care about their customers like this. I'll definitely be coming back and recommending them to my family and friends. Thank you for the outstanding service!"Will be doing another review with photosjerry hartung ★★★★★ I have had 4 other pond builders out to a location in the hill country of desired 1ac pond. All 4 were ready to start escavation without researching soil content, collection potential, or if a well would be needed to supplement water supply. Rick came out several times and brought with him an experienced excavation operator. He took soil samples which he tested, and lasered elevations. His bid was reasonable and in line with others. But after his research we decided that this project was not a good idea. He saved me from a bad experience. But if I was going to proceed he would have been my only choice to proceed with out of the 5 pond contractors that were interviewed.Tyler Sessums ★★★★★ Very nice people to do business with. They showed when we made an appointment and have exactly what we need and provided help and advice for us. We will be back for sure!
