Well it is now July and the end of the driest part of the year. Where we live the end of may and all of June tend to be very dry times. We have been trying to seal a pond for the past two years with not much luck. This year we seem to have gotten it to seal, and hold water for the long haul. I would like to share our experiences with every one here.
How to Seal a Pond.
There are many different ways to seal a pond, some natural and others not so much. I will cover some of the choices here today and then I will share what actually worked for us. If a method did not work for us does not mean that it will not work for you. Keep in mind that even though a specific technique may have worked for us does not mean that you will get the same great results. Now that we have an understanding, lets move on to building your pond.
The first step is obvious, you need to find a good place to start your pond. Look for areas that water may already be collecting. If you do not want to place the pond here, look for ways to re-route the water to a better place.
Once you have picked out a place to install a pond, take some time and decide how big you would like this pond to be. If you don’t plan what to do with the extra water you may end up flooding your property.
You don’t want to flood yourself, so be sure to plan the flow of the water both in and out of the pond. Now that you have an idea of how the water will flow into and out of the pond when it is full, you need to dig out your pond.
Ways to Seal a Pond
The first option we will talk about, is going to be a liner. A liner can work very effectively but in order for this to work you must install it BEFORE you start collecting water.
Not to say that it is impossible to install after. We tried several times to seal a pond with a liner that already had water in it. While very entertaining for the folks watching it was not at all effective.
When you install a good pond liner and take time to seal the seams, you will have a pond full of water in no time. If you don’t know what a pond liner is, it is barrier that you put on the ground that is made out of some form of plastic.
Here is a link to some different kinds of pond liners so you can see what they look like. The main draw back of liners is they tear. If you have animals wandering all over they can easily step on and tear the pond liner. So you may want to look at one of the other options.
Another less natural option is to use a product called Bentonite. Bentonite is a granular form of clay, and is commonly used in drilling operations. The idea with bentonite is to mix it with the dirt at the bottom of the pond.
The clay will create a seal so that the water can not seep in to the ground. I have heard some very good things about using bentonite but we tried many times to get some and were unsuccessful.
Since then I have been able to locate some on amazon you can check it out here. The biggest problem is that you can’t really find bentonite at the corner store. Most likely you will have to order it in.
Natural Ways to Seal a Pond.
Now on to a more natural option, Pigs or cattle. If you take the area where your pond and fence it off and keep some cattle or some pigs in there for a season, the animals will compact the ground and create a seal so it will contain the water for your pond.
This is another wonderful option, but keep in mind that you will have to feed the animals. Cattle eat a lot of food and cost quite a bit to purchase. If you aren’t keeping them anyways this options is very pricey.
While pigs are less expensive to purchase and to feed they have a whole other issue, the smell. Keeping pigs is a smelly en devour and if you don’t keep your pigs down wind of the house it can be almost unbearable at times.
Which leads us to the solution that we finally landed on……. DUCKS. Ducks are much cheaper to purchase at a few bucks each and it also cost a lot less to feed these awesome pond sealers.
The best thing about using ducks to seal a pond is that while they do their job they also produce food for you at the same time. You can eat the ducks and you can also eat their eggs.
If you don’t like the taste of duck eggs by themselves the you can use them to bake all kinds of things. When ducks get into water they defecate, this floats to the bottom of the pool and forms the seal that we have been seeking.
