Flexible,
long-lasting pond liner sheets for permanent seals and leak-proof ponds
Cheap pond liner
is perfect for building a pond. It allows the pond owner to create ponds
of various shapes and depths. Sometime, when it comes to small backyard
ponds I often prefer to use the pre-molded ponds instead of using an EPDM
Firestone 45 Mil Liner...I dunno...it just works great to use a ready-made
pond in the small scale.
I've installed many
of those hard shell ponds and they are fairly easy to install except for
maybe some issue with leveling things out after you've dug the pond hole.
For large ponds over 8 x 10 there really isn't an option for a molded pond
so a liner is the only way to go. Many complete pond kits on the market
include a large piece of pond liner along with the skimmer and filter falls.

When it comes to larger
ponds I almost exclusively use the 45 mil fish-safe pond liner. After 2010
Firestone, one of the more familiar manufacturers, switched to a 40 mil
thickness liner which is now the standard for landscapers and pond builders
although 45 mil is still available. Unless
you are using a molded plastic formed pond or are digging or excavating
a large natural earth pond in blue clay then you will likely need to use
a pond liner.
A pond liner is basically a resistant and watertight membrane that keeps
the water in your pond. Pond liners can be the most expensive piece of the
initial pond build so make sure you measure twice and order once because
the planning of your pond is the key to success!
After you have done the initial layout of your pond and maybe even after
you have sharpened your shovels and started digging the shape of your pond
out of the front lawn you should stop and do some simple calculations to
figure the size of the liner you will need. Establish the size of the liner
before going to far in to your planning as the importance of correct sizing
when using a membrane cannot be overstated. When a liner is costing over
$1.50 per square foot you want to be very careful before you order the sheet
of EPDM that is 380 square feet only to discover you needed a piece that
is 780 square feet! I've been there and it's a long way back!!
So we'll assume
that you will be requiring a pond liner which is also called a membrane.
Smaller basins and backyard ponds only require a lightweight material. We
use a PVC, polyvinyl chlorine, membrane that will resist frost and ultraviolet
light. Sunlight will damage cheap materials so it is best to ensure your
membrane has this protective feature, most do but you should ask your supplier.
Most 20 mil membrane should cost around $1 per square foot and can be bought
in standard sized rolls or get a custom size piece cut at your local garden
supply store as most such retailers carry this and the 35 mil liner that
is slightly thicker and can buy for $1.50 per foot. The 20 mil and 35 mil
materials should come with a 20 year warranty if you place a geo-textile
protective barrier under and on top of the liner.
There is a 45 mil EPDM, ethylene-propylene-diene-terpolymer, heavy -duty
membrane that is available and we often use this strong and puncture resistant
material for waterfalls and streams between two basins. It can cost from
$0.80 - $1.50 per square foot. Using a thicker material will reduce the
risk of a breech or puncture which could result in you're fixing a leaky
pond. Luckily, these membranes can be repaired and sealing foam is available
to help with sealing a pond.
Calculating
pond liner size
Many beginners take measurements from their outline and do some rough calculations
and then scurry off to the pond supply store with such enthusiasm only to
come home with a specially-cut length of material to find that it is too
small. Here is a simple formula to help calculate the dimensions of the
pond liner you'll need.
Width - The formula to determine the width of your membrane is 2
x pond depth + pond width + 2 feet = required width.
Length - The formula to determine the length of your membrane is
2 x pond depth + pond length + 2 feet = required length. .
Example: If
you have a 20 foot long x 10 foot wide pond that is 6 feet deep at the
deepest point, the calculation would look like this:
20 (width) + 6 (depth) + 6 (depth) + 2 (overlap) = 34 feet in length minimum
membrane liner width size required according to the pond liner calculator.
10 (length) + 6 (depth) + 6 (depth) + 2 (overlap) = 24 feet in width minimum
membrane liner width size required according to the pond liner calculator.
In this example you would need a liner at least 34' x 24'...unless you
have a custom cutting facility nearby you may need to buy a standard sized
roll. Many manufacturers offer standard rolls of 45 MIL, 30 MIL and 20
MIL liner at low-cost.
Remember it can be much cheaper to modify your pond plans to accommodate
a standard liner roll size. In the above example
a 30 foot by 30 foot liner can be bought for 15% less than a 34 foot by
24 foot custom piece! Be flexible...that's what pond life is all about!
Don't forget to add whatever you will need to cover the waterfall spillway
if your design calls for that. You can use scrap or leftover pieces for
this, but just be sure you have enough left to do the job you've intended.
As my Bass fishing buddy Jared said to me one day as we drifted into the
shoreline reeds, pond liner is a bit like Budweiser...it's better to have
a bit left at the end of the game instead of running out before the end
of the fourth quarter!

When looking at pond liner there are various thickness and strengths which
resist tearing and puncturing to a lesser or greater degree. A pond liner,
if installed in sharp rocky terrain may need a geo-textile covering and
a sand underlay in order to prevent any sharp edges from causing a hole
that may leak in the future. The 45 MIL liner is the industry standard
and there are a few brands and manufacturers and as long as the thickness
is guaranteed to be the 45 MIL then the only difference you need to consider
is price.
EPDM Liners like the omnipresent PondGard by Firestone® is ideal for most
backyard ponds and can be found in many local garden supply stores, the

The EPDM liners can usually be bought for anywhere from $0.70 per square
foot to $1.60 per square foot depending on the size and shape of the piece.
Custom pieces cost more but standard sizes exist which can cost less per
square foot.
The ultimate in pond liners are the EPDM Linerthat is made of fish-grade
synthetic rubber (ethylene propylene diene monomer). When used as a liner
for tanks or ponds, the stretchability of this premium membrane will be
appreciated. This heavier and more user-friendly than either PVC or polyethylene
liners as well as the most resistant and durable pond membrane on the
market.
Vulcanized seams are guaranteed for the life of the liner. Sold in flat
sheets only. The surface of the liner has been dusted with a light talc
powder to improve handling and storage, so be sure to rinse thoroughly
before adding fish. The actual weight is approximately 30 lbs per 100
ft². These liners ship direct from the factory so you are guaranteed low
costs. The SweetH20® Custom EPDM Liner comes in standard roll lengths
of 50' (priced below). The roll widths are 10, 15, 20, 25, 30, 40 and
50'. All dimensions ±4". Made in USA. 100' long rolls are also available,
Unless it is a fairly small project or if the contractor or builder knows
exactly what they are doing we rarely use the 30 MIL liner or membrane.
Although it can be implicated in a successful build this PVC (Vinyl) Liner,
30 mil that is usually specially-formulated, food-grade PVC material that
is 30 mil thick yet remains pliable in cold weather can sometimes be a
disappointment if extreme conditions are expected. In most fabrications
of this thin pond liner all seams are overlapped and heat welded for strength.
Actual weight is approximately .2 lbs/ft2. All sizes are "nominal" and
may vary by ±3". Vinyl is easy to repair with vinyl repair kits and most
of the liner of this caliber is, of course, made in the USA.
Another thing to ask yourself when building a pond or buying a liner is
: Am I Cheap? Go on...ask yourself....are you cheap? Once upon a time
I built a small pond on my property, nothing big, just a small pond about
800 square feet and I thought I knew better and checked out the different
pond liner materials and I put this cheap plastic liner that was guaranteed
for 10 years in my new pond, and guess what? Everything was fine for 7
years but then I started noticing some extreme pond liner degradation
around the edges. As much as I ignored the problem I knew that all my
landscaping and plantings and filters would have to be removed and I'd
have to start again...all because I wanted to save $150 in pond liner!
I now had to literally rebuild the whole pond because of a cheap streak
running down my planning ledger!. Bad mistake.
Now I make sure my pond liner is guaranteed for 20 years minimum so I
don't have to consider a rebuild every 10 years . If you have a store
nearby that specializes in ponds supplies, buy your liner from there and
if they are knowledgeable and respond to your questions they will sell
you a quality liner if you ask for it.
Some of the big home garden supply outlets such as Home Depot or Lowes
will often not have the highest quality liners available, as these all-in-one
centers are geared towards smaller pond-system installations. If your
pond project is a smaller one that's not too involved and budget is a
factor, then a 20 or 30 mil liner from the Home Depot or True Value Hardware
may be adequate for your needs.
Here's
a vocabulary list of terms that will come in handy when talking about
liner:
ML - Thickness of pond liners are shown in mils. 1 ml equals 1/1000
of an inch or 1/40 of a millimeter. A 30 ml EPDM rubber liner is a good
all-around choice for smaller freeform ponds with a lot of twists and
turns, especially if you are on a tight budget. It is flexible and easy
to handle. For larger ponds with rubber liners, 40 ml and even 45 ml will
work well and last for years. Synthetic plastic liners are usually sold
in 20-40 mil thickness for home use. 40 is better but 20 or 30 may be
just fine in some instances.
EPDM - Ethylene-Propylene-Diene Monomer: This is an industrial grade
rubber available in varying thickens, and is the best bet for most all
pond installations, but is also the most expensive option. It is flexible
and easy to work with, and conforms nicely even when twists and turns
are involved in the pond installation.
HDPE - High density polyethylene - This is a heavy duty synthetic
plastic liner sold in 20-40 ml and up thickens for home pond use. It is
a bit less expensive than rubber liner, molds nicely to tight corners,
and usually comes with a 20 year guarantee. In some situations, especially
large ponds that need to be done economically, this is a good choice.
PVC - Poly Vinyl Chloride: Synthetic plastic liner. This is a budget
liner and is the one that you will probably find at the local home center.
It usually comes in 20-40 ml thickens and will mold nicely around twists
and curves. PVC liners come with a 10-20 year warranty for perfect conditions,
but are definitely not as durable as rubber or even HDPE.
Fish Safe - Always be sure that the pond liner you buy has a "fish
safe" guarantee. The manufacturing process for fish safe pond liners is
different than for other uses, and some liners that at first glance look
like they could work well in a pond will emit gasses and chemicals that
are fatal to fish. For instance, if you know someone who does roofing
work, they might come across some roofing liner that looks like it would
work for your pond. Do not use this, because it will almost surely kill
anything you put in that pond.
One thing to remember is that the heavy-duty membrane is heavy stuff!
Large pieces need to be lifted by several people or by machines. Even
a small 10 x 10 foot piece of 45 MIL membrane can really buckle the knees
so be prepared to carry the weight...it's always best to have a few well-fed
friends on-site to help haul the liner from the UPS delivery van down
to the pond location!!
Compare
& Pricing
When comparing liners it is a good idea to look for forums and reviews
that discuss the pros and cons of various systems. Since the principals
of aeration are scientific and many companies offer products that do basically
the same thing to various degrees of efficiency then it is up to us as
consumers to use our due-diligence before buying a pond aerator. To compare
prices with our recommended systems we have grouped some of the more popular
bottom-diffuser aerator brands together for comparison with our best aerator
systems.

download a printed version of the same steps. Important Pond liners are
not suitable for or approved for roofing applications. If you are measuring
off a completed excavation, use a flexible measuring tape or a rope that
completely conforms to the contours of the excavation. To determine the
full length of liner required, run the tape or rope down into the pond,
exactly following the contours of the excavation, across all the ledges,
to the bottom of the pond, and back out the other side. Then add at least
2 feet or 60 cm (minimum 1 foot or 30 cm per side) to allow for sufficient
liner overlap outside of the pond. Use the same method to determine the
width of the liner. Be sure to measure across the maximum length and width
and at right angles to each other. Example Using one of the above formulas
and including a minimum liner overlap of 2 feet (60 cm) for both length
and width, you determine a required liner size of 19' x 23'. Now all you
have to do is select from either Firestone or Carlisle and look for a
suitable size. In this case, the only suitable liner size is 20' x 25'.

Pond Liners... Pre-formed ponds are great for smaller areas, where forming
a shape using a flexible pond liner would create numerous folds which
could look unsightly. There are many different installation techniques
from a sunken informal finish to a raised formal pool. An informally shaped
pre-formed pond is an ideal habitat for plenty of wildlife and plants
along with a few fish. The edging can be laid informally or formally depending
on the desired finished effect., Basic Rules for Pre-formed Pools Never
position a pool in a area where there is a high water table or flash flooding.
Pre-formed pools must have all round support, ensure you have created
a sand bed for the pool to sit on and pack sand down between the excavation
and the pool sides. Take care over ensuring your pool is level (see Level
Edging) Allow the filled pond to settle for at least a week, then recheck
levels before placing any edging around the pool. With raised pre-formed
ponds it is best to use a dry sand / cement mix (6/1 mix) between the
pool’s side and supporting walls. Pre Formed Ponds at World of Water...
