BENTONITE PILING POWDER
Bentonite has proven to be one of the most effective sealants on the market. The fact that sodium Bentonite swells many times its mass, then forms a strong water and chemical proof seal makes it an ideal, inexpensive, permanent, and easy to install liner. Because it contains no chemicals, no additives, nothing toxic, sodium Bentonite is environmentally-friendly.
Sodium Bentonite is a natural sealant and is used for sealing stock and recreational ponds, dairy and sewage lagoons, and city landfills. It is also effective as a hole plug as well as for controlling dust on highways. Sodium bentonite is one of the “most effective low cost methods” of treating porous soils. It is so effective, that the Federal Government and most states require a liner of sodium bentonite or material comparable, to be used to seal toxic waste lagoons and abandoned water and oil wells. It is environmentally safe, because it contains no chemicals, no additives, nothing toxic.
Sodium bentonite swells 15-18 times its dry size when wetted by water.
Over several years of testing, Sodium bentonite has proven to be one of the most effective sealants on the market. The United States E.P.A. has ruled that all landfills and waste disposal sites must be lined to prevent the leaching of hazardous chemicals into the existing ground water to protect the environment. The fact that sodium bentonite swells many times its mass, then forms a strong water and chemical proof seal makes it an ideal, inexpensive, permanent, and easy to install liner. Sodium bentonite is environmentally friendly and safe to use.
There are several companies selling bentonite clay for various markets. Some of these companies are misrepresenting their product because the public they are selling to does not know the difference.
We at Sturgis Materials are trying to educate the public on using sodium bentonite as a pond sealant.
If you are considering using bentonite as a pond sealant, Please read on!
It is the swelling ability of the sodium bentonite that enables this clay to bond with the soil to create an impenetrable liner in the soil.
The quality of the bentonite deposits will vary. Some deposits of Sodium Bentonite are very high quality swelling deposits, while others are not as good. Some of the best deposits are deep in the ground and will require many man-hours recovering this bentonite.
So a good quality sodium bentonite begins with a good deposit!
All bentonites will contain a percentage of other minerals; Aluminum Oxide, Potassium Oxide, Magnesium Oxide, to name a few and a percentage of sand and silt. It is the process of removing the sand and silt from the bentonite that will produce a higher quality product. The process of removing most of the sand and silt takes time and is costly.
Some companies are not interested in producing a quality product. Thus they will use poor deposits of bentonite and process the material quickly enabling them to sell their product at a cheaper price. However, if this product were tested, it would probably result in a large percentage of sand; something a leaky pond does not need.
In the bottom of a 5-gallon plastic pail, drill 20 to 25 eighth inch holes. Gather enough soil from the area to be sealed to fill about 3 inches of the pail. You can either select the most porous soil, (sand) or a mixture of soil taken from several areas of concern in order to present an “average” soil.
In this soil, mix one to two pounds of bentonite and tamp down in the bottom of the pail. Into this pour a gallon or two of water and see if the bentonite provides the necessary seal. If not, repeat the process and increase the amount of bentonite by half a pound until the water is contained within the pail.
The bottom of the pail represents about one square foot. When you know how many pounds of bentonite it takes to seal the pail, then we know how many pounds per square foot to distribute and roto-till into the pond, dam or other earthen structure.
Mixed Blanket Method
Pure Blanket Method
The Sprinkle Method
In all methods of bentonite application, it’s the swelling of the particles that stop the leak. Bentonite will not stop the leak immediately. Some seepage is to be expected for up to a week after the bentonite is applied. Bentonite will not swell in water containing large quantities of mineral salts or acids.
Sealing ponds or earthen structures:
Disc in or mix the predetermined amount (1 to 4 pounds) of Bentonite sealing and plugging agent per square foot uniformly over the area to be sealed so that a 6-inch blanket of soil and Bentonite sealing and plugging agent is formed. Do not neglect the edges of
the dam or the sides/walls of the pond. This sealing blanket should then be compacted in place. As added protection to the sealing blanket, 2 to 4 inches of local soil or sand should cover the sealing blanket and be compacted.
If the leaking area can be identified and isolated, an attempt can be made to broadcast Bentonite uniformly at 4 to 6 pounds of Bentonite per square foot of surface area into the water over the area of concern.
Note: Bentonite is more effective as a sealing agent when confined. Therefore, every effort should be made to cover the bentonite after it is broadcast with a 2-3 inch layer of sand. This will reduce the potential for dispersion into the water and un-yielded bentonite particles interfering with the gill action of fish.
