Soil preparation before pond liner installation has a major impact on both performance and lifespan. A well-prepared pond base that is smooth, level, and free of sharp stones, roots, and debris reduces the risk of punctures and abrasion. Proper compaction of the soil helps create a stable foundation, preventing uneven settling that can place stress on the liner and lead to stretching or tearing over time.
Good soil preparation also improves how the liner handles water pressure and environmental changes. When the base is evenly shaped and supported with a protective underlayment, the liner can distribute water weight more uniformly, reducing weak points. This minimizes movement caused by ground shifts, temperature changes, or water level fluctuations. By investing time in thorough soil preparation, pond owners can significantly extend the liner’s lifespan, improve water retention, and reduce long-term maintenance and repair costs.
