Fix any leak with sodium bentonite.

Best Pond Sealant in the USA

Sodium bentonite is a natural mineral that seals leaks in any pond regardless of its state, whether the pond is old, new, dry, or has water and fish. Sodium bentonite will reduce water loss.
Our Pond Sealant is one of the most efficient yet low-cost methods to repair or create a new pond.

How it reduces the seepage?

Bentonite Pond Sealant can apply to full or dry ponds.

When sprinkling Sodium Bentonite on the water it will sink and deposit itself at the bottom of the water tank soil pores and cracks, sealing them within a couple of days.

If the pond is dry or building a new pond, the pond sealant can be applied as a pond liner, creating a permeability barrier very efficient, low-cost, and long-lasting seal.

The Bentonite sealant’s working principle is based on the natural property to absorb water and expand itself up to 10 times or more that is useful for solving all water intake problems.

How much pond sealant do I need?

To determine the pond sealant amount that a pond needs, we must know the pond’s area and the type of soil.

The amount of pond sealant per square foot depends mainly on the soil’s porosity. The higher the porosity of the ground, the more product is needed to prevent seepage. If you know the type of soil, you can find the recommended amount per square foot in our Helpful tools section,

To approximate the pond’s area. we multiply twice the most-depth point of the pond and add the resulting number to the length (L). And we also add that same number to the width (W), and we multiply both results L + (Depth times two) x W + (Depth times two), and the resulting number will be our estimated pond area.

To facilitate the calculation of the amount of Bentonite you have to use, you can use our Bentonite & Pond Area Calculator.

How to use bentonite clay as pond sealant

While there are three main primary techniques available for applying sodium bentonite pond sealant, there are several factors you need to consider before selecting a proper application method.
The pond’s current state, along with the depth and dimensions of the pond and the soil quality, is of paramount importance when deciding on the application of the sealant to the pond.

The Blanket Method for Sodium Bentonite

This method is by far the most effective and popular method for bentonite pond sealer application.

First, any debris such as dead vegetation, including roots, logs, moss, trees, rocks, and other undesirable material must be removed in this method.

In the second step, all surface gaps, holes, or crevices must be filled with a mixture of 1 part of bentonite and five parts of soil (depending on the ground and using the reference table below on our Helpful Tools & Recommendations section.

This method is to completely cover all holes and gaps that are found at the surface.

A layer of bentonite sealant will be applied in the next step, spreading it to create a nice evenly blanket along the entire surface.

Once the bentonite has been applied on top of the surface, it is required to till it in or disk it in, just about 3 ~ 4 inches into the ground and compact. (Remember: Prevent bentonite from going into deep, because the more profound the product is in the soil, the more the bentonite is diluted.)

After you have compacted the bentonite, and if possible, you can spray water, wet the treated ground, and compact again.

The pond is now ready to be filled with water. Care should be taken in maintaining smooth and steady water flow in the pond so that soil or bentonite layers are not disturbed.

The Mixed Blanket Method for Sodium Bentonite Pond Sealant

The goal of this method is to have a very soft and even pond bottom.

As mentioned in the previous method, the mixed blanket method also begins with cleaning up all debris at the bottom and along the entire bed and then fill the holes.

The crucial move in this approach is to till the surface-go deeper in the process between 3 and 4 inches.

The purpose is to make the surface smooth and consistent by dragging the soil all along the waterbed.

Then apply a layer of Bentonite-soil mixture accordingly with the recommended ratio of bentonite per sqft area, cover it with 4 inches of soil, and compact. The final layer must be thicker if your livestock is going to have access to the pond.

The Sprinkle Method for Sodium Bentonite Pond Sealant on a pond with water

Do you want to minimize water leakage in your lagoon or pond? Do you want to avoid the drainage of a water tank?  Sodium bentonite sprinkle method of applying and treating your pond liner to plug water drains.

 

This application method is used when a pond cannot be drained, either because of its size or for some other reason. When leaks have isolated, this approach can also be used. The process is less successful than the two previous methods, as there is no removal of trees, roots, and vegetation from the pond. And this method is not as accurate when sprinkled above water (could be a hit and miss).

In all application methods, it is important to notice that it may take a few days for the seepage to stop entirely because this is the time bentonite takes to hydrate to its fullest capacity and form a solid lining at the bottom. However, it is critical to know this for superior results: the required amount of sodium bentonite per square foot must be applied based on your soil type.

Helpful Tools & Recommendations

How do I determine how much Bentonite is needed per square foot to seal my pond?

Depending on the type of soil on your pond and the pond’s size, how much sodium bentonite clay we can recommend applying.

The following table will help you decide the required amount of pond sealant needed concerning the square foot of different soil conditions.

This table is based on Lonestar Minerals quality bentonite mix mesh powder for ponds.

Powder mix mesh granular Pond sealant:

Soil condition:                  Amount of bentonite clay:

Rock or gravel: 3.0 to 3.5 lbs. of bentonite per square foot area.

Clean Sand: 2.5 to 3.5 lbs. of bentonite per square foot area.

Silty Sand: 2.0 to 2.5 lbs. of bentonite per square foot area.

Sandy Silt 20% Clay Min: 1.5 to 2.0 lbs. of bentonite per square foot area.

Clay soil: 1.0 to 1.5 lbs. of bentonite per square foot area.

How do I calculate the area of my pond?

Pond Size Area Calculating Formula:

Step 1.- Multiply your depth of deepest point by two, and the resulting number needs to be added to the pond’s length dimension.

Then repeat this process, multiply your depth of deepest point by two, and the resulting number needs to be added to the width dimension of the pond.

(Length + Depth x 2= “X”) and (Width + Depth x 2= “Y”)

Next,

Step 2.-Then, multiply the resulting number from both equations, from the above formula.

(L X W = Total Pond Area)

*This formula gives a reasonable approximation of the size of your pond.

To estimate the area of a Circular Pond:

Follow this process below!

Step 1.- You will need to measure the circumference of the pond. Once you have acquired those measurements, you will divide the circumference by two times pi. This resulting number is the radius of the pond.

Pond Circumference / (2 X Pi) = Pond Radius

Step 2.- Once you have solved for your radius. You will square the radius and multiply it by pi.

(Radius^2) X Pi = Pond Area

Feel free to contact our experts through our contact page or give us a call for any questions or concerns. We can calculate the square footage for you! (To calculate your pond square footage size area, we need the longest pond length, longest pond width, and deepest pond depth).
