A leaky pond which contains water can also be sealed by pouring a slurry of bentonite, or spreading granular bentonite over the surface of the pond. This technique is usually not as successful as applying bentonite to the dry pond bottom because it is difficult to achieve an even application of the material.
Will a leaking pond seal itself?
Treated areas that might become exposed and dry during water level fluctuations should be sealed with 12 to 18 inches of gravel to prevent erosion, cracking, and perforation. Ponds that seep a little may seal themselves through natural siltation.
How do you seal a pond without a liner?
Use soil additives such as bentonite in applications of 10 to 30 pounds per square yard of surface area to create an impermeable layer. Bentonite is a colloid that expands to 10 times its size when wet and seals soil pores.
How do I stop my pond from seepage?
Plastic Liners Plastic or vinyl liners can be used in most conditions to seal a leaking pond. They are used most frequently on small ponds or where severe leaks occur repeatedly. These liners can provide a watertight seal under the right conditions, but they are expensive compared to other techniques.
How do I make my pond safe to swim in?
In general, it is recommended that all ponds and lagoons be fenced with an eight foot locked, chain link fence with posted signs (e.g., No Trespassing, No Swimming, etc.). Non-posted, non-fenced ponds increase the risk of a lawsuit if uninvited swimmers are injured or drown.
How long does it take for bentonite to seal a pond?
It takes about a week for the bentonite to achieve its maximum hydration state. In 3-5 days, the water level should stabilize and after that period, in some cases, it will raise.
Why does the water level in my pond keep dropping?
Evaporation. Causing water levels to drop roughly 1 inch per week, evaporation is the most common cause of pond water loss. Factors such as location, time of year, pond size and especially weather, can affect the rate at which evaporation occurs.
How do you bentonite a pond?
Mix soil with bentonite at that rate in lbs/square foot. Thoroughly blend the soil and dry granular bentonite until the mixture is uniform. Add 3 cups of water to the soil bentonite mixture and mix again until moisture is evenly distributed. Firmly tamp the soil/bentonite mixture into the bottom of the bucket.
Can a pond hold water without a liner?
There are several options for constructing a new pond without a liner or cement shell. The easiest is to excavate the pond into the local water table and use the ground water. When ground water is within a few feet of the ground surface, gradients into the pond from the edge can be shallow.
Can I just dig a hole for a pond?

Will kitty litter seal a pond?

Whether you use pure sodium bentonite or clumping cat litter, know this: once this stuff gets wet, it is gooey. Gooey like the slickest, wettest, slimiest pond edge you’ve ever slipped on.
How does bentonite work to seal a pond?
Bentonite pond sealer, a natural clay product, chemically attracts to itself and swells up to 12 times its dry size when moistened. Expanded bentonite forms an impermeable gel seal which makes an excellent pond sealant. Sodium Bentonite is environmentally safe and does not affect the water, livestock, or wildlife.
Is it safe to swim in small ponds?
Yes, you can swim in a backyard pond as long as the pond is big enough and the water is clean. A pond needs to be free of harmful bacteria and large enough to support a swimmer without destroying its ecosystem. You also might want to consider building a backyard pond for the purpose of swimming.
How do you know if it’s safe to swim in a pond?

How do you apply bentonite to a leaking pond?
Begin by simply sprinkling the prescribed amount of granular bentonite (Granular Seal) on the water surface and allow it to fall into place. The granular bentonite particles will sink to the bottom of the pond or be drawn into porous areas where they will swell and reduce the seepage rate.
How much bentonite do I need for a 1/2 acre pond?
