The Best Pond Liners of Each Type

Choosing a Typical Pond Liner (Flexible)

This is quite a straightforward task. First of all, find out what size of Liner you will require – accounting for length, width, and depth. Also, as a contingency, remember to buy slightly oversize – excess can be trimmed later on.

Many cheap materials are available, however, we strongly advise you purchase a high quality Liner with good thickness and quality. It is worth it in the long run as your pond will be far less likely to puncture or tear.

Remember to budget for a material to Line underneath you’re Pond Liner – to help cushion it against the bare ground. This is typically sand, although it is possible to purchase a dedicated product if you would prefer.
