Yes, pond liners can be used in both new and existing golf course ponds. In new pond construction, liners are typically installed during the initial excavation and construction phase before filling the pond with water, providing an immediate barrier to water seepage and preventing soil contamination.
In existing ponds, introducing a liner can be part of a renovation or maintenance effort to address issues like water loss, erosion, or contamination. Installing a liner in an existing pond typically involves draining the pond, preparing the base to ensure it's smooth and free from sharp objects that could puncture the liner, and then laying the liner. This process can significantly extend the life of the pond, improve water quality, and reduce maintenance needs.
