What can you put in a pond to stop a leak?
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 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 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 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 do you put bentonite in a pond?
Spread the bentonite clay evenly over the entire soil surface at a rate of 2 to 3 pounds per square foot, which is equivalent to a 1/4- to 3/8-inch layer. Use a 1/2-inch layer of bentonite in free-draining soils with little clay content. Bentonite is typically purchased in 100-pound bags.
