Pond Liner Dimensions and Purpose

This 10 by 13 foot black pond liner creates a watertight barrier for fish ponds, water gardens, fountains and waterfall bases. It is suited to gardeners and landscapers who need a durable, flexible membrane to hold water and protect aquatic life from soil contaminants.

Upgrading From Thinner Liners

The 20 mil thickness replaces thinner, less durable sheets that tear easily on sharp rocks or expanding roots. The jump is worth it when the installation site has abrasive substrate or when a longer service life reduces the frequency of pond draining and relining.

LLDPE Material Constraints

The liner uses linear low-density polyethylene rated for approximately 10 years of UV exposure without cracking or splitting. It cannot withstand prolonged contact with petroleum-based chemicals or extreme heat, and it is not designed for potable water storage or structural load-bearing applications.

Questions about this item

What are the exact dimensions of the 20 mil LLDPE liner so I can size the excavation?

The liner measures 10 x 13 ft (3 x 3.9 m) with a thickness of 20 mil (0.5 mm) and weighs 13.6 lbs (6.2 kg).

What is the recommended way to install the liner and what step is commonly missed?

Excavate a smooth, level base free of sharp objects, lay the pliable LLDPE sheet loosely to allow for settlement, then secure the edges with rocks or edging; the step often missed is leaving enough slack so the liner does not stretch tight when the pond fills.

How long will the black LLDPE material last before it needs replacing?

The manufacturer rates the UV-resistant LLDPE liner for a 10-year lifespan under normal sunlight exposure.
