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.
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 can I seal my pond naturally?
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.
How do I get water to stay in my pond?

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 you find a leak in a pond?

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 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.
Can I add hose water to my pond?
Can You Put Hose Water in a Pond? Much like tap water, it’s highly unsafe to add hose water directly into the pond. Not only does it have chlorine, but your hose likely has several types of algae or bacteria. These substances can be horrible for the plants and fish in the pond.
How deep should a pond be to hold water?
Water gardens in moderate climates usually need for an area of the pond to be at least 2 feet deep. Colder climates require a depth to provide at least 12″ to 16″ of water below the freeze zone.
How much water loss is normal in a pond?
It is normal to lose 2-3″ of water in a week from evaporation. Garden ponds from 500 to 2500 gallons and larger usually only require small weekly watering.
How much does a pond evaporate in a day?
Gallons Evaporated Per Day A pond in direct sunlight will lose around 1% of the gallons pumped per hour over the course of the day.
Is rainwater good for ponds?
Wait for the rains: Let your pond fill with rainwater. It’s OK for pond water levels to drop or even for some wildlife ponds to dry out completely (not so great for fish ponds, of course).
Can I just dig a hole for a pond?

What can you use to line a pond?
Choosing the Right Liner for Your Pond – PVC, Rubber, Or Mud? Every pond needs a liner to stop water from leaking out through the pond base. The most affordable liner is 0.5mm thick PVC. Thicker at around 0.75mm, this rubber pond liner is more durable and flexible than PVC.
Can you line a pond with concrete?
A concrete pond correctly built will last for many years. This method pre-dates more modern technique and it does look breathtaking when done well. Either way a smooth surface is required, so it is not rough for the pond fish.
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.
