Frequently Asked Questions

What size liner do I need?

The formula for sizing a pond liner is
POND LENGTH + (2 TIMES DEPTH) + 2' = LINER LENGTH
POND WIDTH + (2 TIMES DEPTH) + 2'= LINER WIDTH
Example:
A 12' long, 7' wide and 3' deep pond is...
12' + (2 * 3) +2' = 20' Long
7' + (2 * 3) + 2' = 15' Wide

How many gallons is my pond?

The formula for determining the number of gallons is:
FOR SQUARE AND RECTANGULAR PONDS
Length * Width * Depth * 7.5 = Gallons

FOR ROUND PONDS
RADIUS * RADIUS * 3.14 * 7.485 = Gallons
Example:
12 * 12 * 3.14 * 7.485 = 3,384 Gallons

Underlayment for Pond Liner

This Listing Includes UnderGuard Geotextile Underlayment

UnderGuard Geotextile Underlayment™
The biggest contributors to Koi pond, water garden and waterfall failures are poor, unstable soil conditions. Nonwoven geotextile fabrics are perfect for stabilizing soil, preventing rocks and roots from penetrating pond liner and for creating ’rock pads’ to cushion large rocks and boulders placed in the pond on top of the liner.
Underlayment is EASY to install
Underlayment is manufactured in 5’, 10’ 15’ widths and will ship to you in one or more pieces equal to the total square footage of the pond liner in liner/geo combo. Simply lay the pieces next to each other and install the pond liner. Use any extra underlayment to create pads for large rocks and boulders placed inside your pond.

Liner Repair Kits

Seam Tape Semi-cured EPDM rubber, coated on both sides with a highly resistant and aggressive Butyl adhesive. Used to splice together two sheets of EPDM pond liner.
Flashing Tape Very flexible, uncured EPDM rubber, coated on one side with a resistant and aggressive Butyl adhesive. Stretches across wrinkles and around pipe penetrations. Use to cover (top-dress) EPDM pond liner seams.
Cover Tape
Cured EPDM rubber, coated on one side with a resistant and aggressive Butyl adhesive. Used on flat, non-stretching surfaces.
Primer / Splice Wash A low VOC solvent used to prepare, clean and prime EPDM sheets prior to applying peel and stick tapes.
Lap Sealant Self-leveling edge treatment used to ensure a leak-free, watertight seal when seaming together two sheets of EPDM pond liner.

FAQs & Calculations to Help Select the Correct Liner Size

1. What is EPDM?
EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e. ketones, esters, and alcohols).
 
2. What is the maximum size sheet for EPDM membrane?
Sheets as large as 50 feet in width are produced mostly for use in ballasted and mechanically fastened applications. Narrower widths are also produced to offer applicators greater flexibility in positioning membrane.

Narrower sheets are also produced without factory seams (seamless) for use primarily in adhered and mechanically fastened applications. The major advantage of seamless material is the elimination of factory splice T-joints that occur when factory seams intersect with field splices. This reduction in T-joints significantly increases the potential for watertight performance by eliminating potential "water channels" into field splices.

Both narrow and wide sheets are manufactured in varying lengths from 50' to 200'.
 
 
3. What size liner do I need?
The formula for sizing a pond liner is:
(Pond Length') + (2 x Pond Depth') + (2') = Liner Length'
(Pond Width') + (2 x Pond Depth') + (2') = Liner Width'

So... if you want a finished pond that is 12' long, 7' wide, and 3' deep; then using the formula above, the liner size you need is:
(12') + (2 x 3') + (2') = 20' Long
(7') + (2 x 3') + (2') = 15' Wide

This basic formula will work for ALL pond shapes.
 
4. How Many Gallons of Water does My Water Feature Hold?

Rectangular Ponds

Length x Width x Average Depth x 7.48 = Gallons

Example: A rectangular pond 15’ long, 10’ wide and 1.5’ Deep Pond is...

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Oval Ponds

Length x Width x Average Depth x 0.8 x 7.48 = Gallons

Example: An oval pond 15’ long, 10’ wide and 1.5’ deep is...

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Round Ponds

Length x Width x Average Depth x 7.48 =Gallons

Example: 15’ long, 10’ wide and 1.5’ Deep Pond

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
 

Streams

Length x Width x Average Depth x 0.25 x 7.48 = GALLONS =Gallons

Example: 15’ long, 10’ wide and 1.5’ Deep Pond

15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
 
5. How deep should I make my water feature?
For fish ponds, a depth of at least 18", or deeper is recommended. Healthy fish LOVE to move up and down, as well as side to side!
For water gardens, the water feature should have a depth of at least 12", or deeper.
Check your local fence requirements (building codes) and freeze line depth.
 
6. How Big of a Pump Do I Need?
Minimum pump size is determined by pond type, water volume, head height and friction loss. The minimum pump size recommendations are:

Water Garden, Few Small Goldfish

Circulate total pond water valoume every 2 hours.

Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.

Fish Pond, Several Small Fish

Circulate total pond water valoume every 1 hour.

Example: 3,800 GPH pump for a 3000-gallon pond with 2’ waterfall.
 

Koi Pond, Several Large Fish

Circulate total pond water valoume every 3/4 hours.

Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.

Calculating Head Height

Dynamic head pressure is found by taking the vertical height of your waterfall; the distance between where your pump is (typically in the skimmer) and where your waterfall is, and adding the static head pressure (pipe and fittings) 1’ for every 10’ of tubing and 1’ for every elbow or “T” fitting.

Example: 3' (vertical height) + 2.5 (25' of tubing) + 2' (for 2 elbows) = 7.5' of Dynamic Head Pressure

Note:It is important to take into consideration while calculating how much flow will be at the top of your waterfall by accounting for the head height due to the laws of fluid dynamics. Please refer to the flow chart above to help choose the correct pump.
