How to Make a Concrete Pond for Kids

Draw the shape of the pond on the ground using spray paint. This is determines where you dig, so adjust the shape and size as needed. Dig along spray painted outline to define the shape of the pond.

Dig the pond inside the dugout pond shape. The depth of the pond depends on you. Consider where you want the water level to be when a child is sitting on the bottom -- neck level, or mid-chest level, for instance. If you are using a pre-shaped pond liner, dig the pond as deep as the liner allows. Otherwise, stagger the pond depth as desired.

Place a liner in the dugout structure. Liners are available at home improvement stores. Smooth the liner.

Mix together gravel, concrete and sand mix. You need one part concrete and four parts each concrete and sand. Stir in enough water to make a thick paste. Apply the concrete to the surface of the pond lining. Smooth it as necessary with 2-inch-by-4-inch board. Use the board like a trowel. Make the concrete a uniform 2 inches thick.

Allow the kids to decorate the concrete while it is still wet. Give them sticks, stamps, cookie cutters or even their gloved hands to make designs in the concrete. Another idea is to let them make mosaic designs in the concrete using colored tiled or stones.

Leave the pond to sit for five or six hours. Place a sheet in the pond to protect it while filling. Fill the pond with water. Remove the sheet. Allow the concrete to set for seven days.

Drain the water from the pool using a bucket or a siphon. Alternatively, if you have access to an electric pump, use that.

Paint the inside of the pond. Allow the kids to paint their own design. Let the paint dry completely.

Refill the pond with fresh water before allowing children to play in it.
