Fix ponds and lakes

Stop water filtration on you pond using bentonite

What is the pond problem, and what caused it?

The main problem is the type of soil, the porosity of the ground, and not treating or lining the water tank when built.


We’ll supply the necessary equipment, operators, and mineral to treat your pond.


When building a pond, a small lagoon, or any water body, the appropriate steps must be taken into consideration to guarantee that your pond avoids any leak. Most water bodies will lose significant water over time, mainly if it is on a permeable surface. Sodium bentonite may remove or prevent water drainage in a quick, efficient, and environmentally friendly tank sealer.

Most common causes for leaks on ponds

A variety of factors may cause leaks in the pond. Perhaps the most common cause is the inadequate building of the foundation of the creek. In short, by building the pond correctly from the start, a leaking pond can be avoided. Areas of sand or gravel or bedrock fractures that have not been properly filled with soil during construction can gradually leak out.


Trees may also contribute to leaks along pond banks or at pond dams. Removing the trees from the pond could also be necessary. Leaks also originate from outlet pipes in older ponds that rust and leak under the water.


Trees can also be responsible for the frequent loss of water in a pond. Water-loving plants, such as willows and maples, frequently flourish along the banks of ponds.  Water is drained from the pond by the roots of these trees as they grow. Water loss from the pond would depend on the pond’s design, plants, number of trees, and pond baselines (liner).


The rapid loss of water, which slows or stops losing water, is also a characteristic of a pond with bank leaks. In this case, the leak spot is generally on or above the water surface on the reservoir’s edge. In the event you can’t locate the general position of the leak, you would undoubtedly need to drain the body of water and thoroughly rebuild the whole pond bottom.


The commitment and cost of fixing the leaking pond are closely related to the ability to locate the cause of the leaking. Unfortunately, the source of the leak can be challenging to find.

Helpful Tools & Recommendations

What are the physical Specifications of our different mesh size particles of our line of products?

We offer a select milled clay product for pond sealant that is a mix mesh powder granular product from fine 200 mesh powder to a 40 mesh mix.

This pond sealant is by far the best product for this application.

If you were to use any other granular bigger particle size chips, you would need twice or three times as much to perform as good. (Please see the picture of our product so you can have a better idea of our product) to give you an example, if you hold our product in your hand, you’ll feel like you’re holding beach sand

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 size of the pond is how much sodium bentonite clay we can recommend applying.

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

This table is based on the Lonestar Mineral 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.

Sandi 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 length dimension of the pond.

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”)


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

For any questions or concerns, feel free to contact our experts through our contact page, or give us a call. 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).

What equipment is needed for unloading our product from delivery truck?

You’ll need equipment to unload 3,000 lbs super sacks or 2,500 lbs pallet from a flatbed truck.

These super sacks have straps on top to grab with your tractor, excavator, front loader, bobcat, or forklift.

Please make sure you can lift a 3,000 lbs super sack since must of the time. The super sacks do not have wooden pallets underneath; if you require pallets, please call and request on your order (cost per pallet will be added to your order).

All our super sacks come with a very efficient discharge valve. The location of the discharge valve is underneath the super sack. To efficiently release the pond sealant, you must pick up the sack and untie the valve to start pouring the liner on top of your soil.
