Advantages of using bentonite to repair a pond

At Lonestar Minerals we repair ponds using bentonite pond sealer, simply because it is the best way to seal your pond naturally. Bentonite itself is a low cost material, easy to apply and so absolutely safe it can be held in the palm of your hand without concern. It’s effectiveness is very high when the bentonite is properly applied and the results are almost immediate.


Bentonite is a versatile solution that can be applied in both ponds with water or dry ponds. In some cases, it might be recommended to drain the pond to repair the leakage.However, there are cases where the bentonite is applied to ponds that are holding water, either by just sprinkling granular bentonite over the water or by blasting the affected area using pressure.


One of the biggest advantages of bentonite is that there is no risk of “punctures” or “tears” which tends to be one of the biggest disadvantages of rubber liners. The bentonite is mixed into the soil of the pond, only adding to it what it needs to be able to hold water. You can safely use bentonite for fish or wildlife ponds and it can also be safely used as an irrigation or livestock pond.

There are some other signs that your pond is leaking and needs a repair service. Besides the obvious sign of the water level lowering rapidly, you may find small puddles outside the edge of the pond. Or you may see plants that are not on season growing near the edges of the pond due to the wet underground. Another typical case is purchasing a property that already has a pond, which doesn’t seem to hold its water level. Figuring out how to repair a pond on your own can be challenging and stressful. Consider a pond repair service. Having an expert opinion can save you money and headaches in the long run. If you’re building a new pond, consider using bentonite as a pond liner.



We recommend applying the bentonite to a dry pond. However, yes, it can also be applied to a pond with water (wet application – sprinkle method), but that introduces several more variables into the equation. It may not be as effective as using it in a dry pond.



Every liner has its advantages and disadvantages and, of course, there are several schools out there. We believe that passive pond liners are a good option for garden ponds (maybe two or three thousand square feet), but when it comes to farm ponds, ranch ponds, or artificial lakes, bentonite is less prone to puncturing or degradation. In our experience, the initial investment is quite similar. Still, bentonite has the upper hand in the long term, with fewer maintenance costs and creating a natural pond ecosystem and not just a water retention tank.



Bentonite is a great pond sealant, but the effectiveness of the seal depends on the quality of the mineral and the correct application. Often, our customers ask if they can do it themselves. Our answer is always the same: if you haven’t done the deed before, we strongly encourage you to trust our expert team to help you figure out what the problem is and the best way to get your leaking pond repaired.



Our Bentonite Pond Sealant Mix Mesh is unique and has been developed using our 50+ years of experience in the field. We offer a select milled clay product for pond sealing that is a mix-mesh powder-granular product combining several mesh sizes, allowing the performance of this mix-mesh pond sealant to be superior to other similar products in the market.



The most important factor in determining the amount of bentonite pond sealer required is the type of soil of your pond. Depending on it is how much bentonite pond sealant we recommend applying per square foot.

Here are some reference values that can help you estimate the required amount of bentonite to seal any area (based on the Lonestar Minerals quality bentonite mix-mesh for ponds). Or, if you prefer, we have available a Bentonite calculator to easily approximate the amount of bentonite required for your pond.


Soil condition → Pond sealant per sqft
Rock or gravel → 4.5 to 5.0 lbs/sqft
Clean Sand → 3.5 to 4.5 lbs/sqft
Silty Sand → 3.0 to 3.5 lbs/sqft
Sandy Silt 20% Clay Min → 2.5 to 3.0 lbs/sqft
Clay Soil → 1.5 to 2.0 lbs/sqft
