1. Pond Size and Liner Thickness:

  • Measure the pond's length, width, and depth. This will determine the liner's minimum required dimensions. Factor in additional material for overhang and folds to accommodate curves and edges.
  • Liner Thickness: Thickness is crucial for durability and depends on pond size, depth, water volume, and potential environmental stresses.
    • Small ponds (less than 3 ft deep): 16 mil HDPE might suffice.
    • Medium ponds (3-6 ft deep): 20-30 mil HDPE is recommended for better strength.
    • Large ponds (over 6 ft deep) or high stress environments: Consider 40 mil HDPE or thicker for maximum durability.

2. Liner Strength and Puncture Resistance:

  • HDPE liners come in various thicknesses (mil) impacting strength. Consider potential stresses like rocks, roots, or foot traffic near the pond.
  • Inquire about the liner's puncture resistance rating for additional peace of mind.

3. UV Resistance:

  • Sunlight exposure can degrade HDPE over time. Choose a liner with UV inhibitors to ensure long lifespan.
  • Many manufacturers offer warranties against UV degradation, so inquire about the warranty period.

4. Liner Seaming Options:

  • Multiple pond liner panels might be needed for larger ponds. Ask about available seaming options, such as heat welding or special tapes, to ensure a watertight seal.

5. Environmental Considerations:

  • For fish ponds, inquire about the liner's inertness and potential leaching of substances that could harm aquatic life.
  • Consider local regulations or recommendations for pond liner materials, especially if the pond is intended for wildlife or public use.

Additional Tips:

  • Ask for product specifications and datasheets from the manufacturer or supplier.
  • Research reputable HDPE liner brands known for quality and durability.
  • Get quotes from multiple suppliers to compare pricing and available thicknesses/strengths.
  • Check with a geotechnical Eingineer for complex pond projects 

By considering these factors, you can make informed decisions when purchasing HDPE liners for their pond projects.
