Backyard pond
liners come in a variety of kinds such as: concrete, fiberglass,
rigid plastic, and flexible plastic. Each backyard pond liner has
its disadvantages and advantages, but this article will focus mainly
on concrete and fiberglass liners. If you are going to have fish in
your pond, then concrete pond liners are not recommended. Concrete
liners release a toxin into the water that is lethal to the fish.
Concrete liners will work perfectly if you are just interested in
plants in your pond.
All the other backyard pond liners are aquatic safe. The real difference
between the backyard pond liners is their ability to resist UV rays,
the weathering, their lifespans, the cost, and their ease of installation.
Concrete and fiberglass are the most expensive backyard pond liners.
Concrete also should be installed by an expert, but it will last forever.
Fiberglass has a lifespan of 50 years, but can be installed by the
owner. It is the easiest installation as there is no need to dig a
hole. Fiberglass is more resistant to weathering than concrete as
it expands and contracts with the heat and cold, thus preventing cracks.
For most backyard pond owners today, fiberglass is desired far more
than concrete.
