Backyard Waterfall and its Features

 The depth of your backyard waterfall  hole about what the depth of the preformed liner is. Dig the shape of the hole match that of the preformed liner as closely as possible, for a good tight fit. However, if  you’ve made the hole  biger, use sand or soil to fill up it.

Flexible liner is most reliable material for waterfalls and ponds. You can simply use one piece for your project or join two or more pieces together (depending on shape). But you need to use the glue and tape recommended for the each kind of liner.

You can buy preformed liners for your waterfall or pond construction, or even build the waterfall bottom from concrete, but be careful if you live in an area with cold winters. The preformed liners and concrete can crack, causing leaks. A better choice is to use a flexible liner and cover it with natural stone.
