Surprisingly, cement or concrete is the worst choice for a pond liner. Stone is subject to the winter cycle of freezing and thawing, which is more likely to cause a crack. This is more likely to be used in elaborate and large construction projects of landscaping plans.

Small water gardens often use fiberglass ponds, an easy purchase that includes easy installation. Larger ponds will use a durable vinyl sheets that are placed in the dug out area. Sometimes other liners are used, ethylene propylene diene monomer (EPDM) is a popular choice as well.

Before starting any pond construction project, make sue to check with your local municipality to check for regulations or requirements.

    • Measure distances, and outline the intended area in rope or chalk lines
    • Begin digging to exact measurements and shape, be sure to check for level periodically
    • Line the area with small pebbles, sand, or geotextile as needed. Line the pool.
    • Consider using a licensed electrician to install pumps, filters, and lightning.
    • Add surrounding plants
    • After construction is done, fill the pool, and place the marginal and submersible plants
    • Wait to add fish, until 2 weeks later, once the chloramines levels are gone. Be sure to keep pH between 7-10
