are made of impermeable materials designed to retain water. We recommend buying the correct type and thickness of pond liner to meet demands of pond size and reduce maintenance issues over its lifetime. Here are a few common mistakes to avoid when buying and installing your liner: • Guided by price alone: We recommend you choose a membrane that is thick enough to resistant puncturing, one that is not likely to deteriorate when exposed to the sunlight and that is strong enough to line a pond for many years. It is worth spending a little more upfront to avoid problems later. Plastic or PVC liners are not as durable as rubber liners such as Butyl or Epalyn. The best choice for a garden pond would be a 30 mill thick HDRPE liner.
• Ordering the incorrect size pond liner: Once you have dug the hole, measure it accurately in three directions – the length, breadth and depth. Then go online to put these figures into a pond liner size calculator to get the exact dimensions. Remember to factor in extra for the lip to anchor the liner over the edge of your pond – at least 2 feet/0.15m overlap to go around the entire rim of your pond.
• Failure to secure the edges of the liner: When installing the liner, generously overlap the edges to make sure your feature is water tight. If the overlap is insufficient, the sides of the pond will become exposed as you start to fill your pond with water. The overlap must then be secured in place with your choice of edging material.
Avoid these mistakes to ensure you create your dream garden pond that will give you years of pleasure.
