How to Install a Koi Pond
LESLIE: Now we’ve got Lee in South Carolina on the line who wants to build a koi pond. How can we help you?
LEE: Off the deck of my house, in the one corner, I’ve got a bridge going to a gazebo. What I want to do is – 2 feet off of the gazebo, I’m doing a raised flowerbed. And from the flowerbed – 4 feet out, all the way around the gazebo – I want to do a koi pond.
And everyone keeps telling me that you’ve got to do it in concrete, because it’s – with liners, it would cause too many – you’d have to have too many liners and then sealing them. And it’d be a lot more of a problem.
TOM: Well, there’s a lot of ways to build a koi pond and most folks use liners.
LESLIE: Well, you have to use something. So, you can either build almost like you would a small pool and pour a concrete foundation – I say “foundation” for lack of a better word but a concrete form. Or you can get a plastic pool form. They’re black. You see them at – I know the home center by me that sells koi – it’s actually a garden center that sells koi and pump equipment for water features – has a variety of sizes of these black sort of – they look like kiddie pools, essentially. But they’re interesting shapes and you dig out and then place this in the ground.
Or you can get the black liner, which comes in a variety of widths and thicknesses. And then you would dig out the formation that you like, especially it seems like yours is a bit more specialized and free-formed and has to sort of fit into a different area of measurements that you have specific ideas in mind. So the liner is probably better, because it will work with your specific dimensions.
And you’ll dig out. You’ll have to dig the slope into it, as well, if you want shallow areas or deep areas. You’ll have to dig that all in, as well. Then you’ll put sand down, just to keep a smooth area, and then you’ll put the liner in.
And it sort of, when you put the water in, will start to take the shape of that area. And then what you’ll have to do around the top, on those edges, is you’ll have to use all-natural rocks and large stones to hold that down and hide all of that lining. But there’s no reason why you can’t use a plastic liner.
LEE: OK. Alright. Thank you.
