Add an above ground water pond to your backyard or lawn to add a waterscape without excavating an area. Add a fountain or house Koi, goldfish or attractive aquatic plants in your pond. Let your creativity flow when landscaping around your above ground pond to create a tranquil spot where you can spend endless hours by yourself. An above ground water pond is easier to install than a traditional one since you do not have to spend hours bending over to dig a hole in the ground.
Determine an appropriate spot in your garden for the above ground pond. Keep it small if you're using it only for plants, but make it larger if you're using it for fish, and put it in a spot that receives plenty of shade. Choose a level spot for your pond.
Outline the planned shape of your pond with spray paint or powdered chalk.
Lay a row of cinder blocks over the chalk line to form a first course of your above ground pond, spacing them ½- to ¾-inch apart. To break a block in half, simply position a chisel over it and pound the chisel with a hammer. When you're done with the first row, lay another row of blocks over the first course, but stagger them for added stability like you would a brick wall, as opposed to ensuring their ends are lined up.
Line the inside of the pond and the cinderblocks with roofing felt to protect the pond liner from holes or any damage. Also insert folded roofing between sharp cinderblocks to cushion them.
Spread the flexible, thick pond liner over the base, ensuring it overlaps the blocks and overhangs all the way around the pool by several inches. Fold out the creases at the base to ensure it is completely smooth. Fill the pond with several inches of water so any leftover creases or folds are visible, and then remove them.
Stack flat fieldstones inside the pond, next to the cinder blocks, until you reach the top. This covers the liner at the sides of the pond. Also spread a layer of fieldstones on top of the cinder blocks, and stack them around it on the outside as well. Trim excess liner off.
Install a pump and pond filtration system according to manufacturer's instructions to keep the water clean. Fill the pond with water from a garden hose, and add aquatic plants or fish to it.
