Building an Above Ground Pond
To build an above ground pond with a 5 foot high berm approximately 118' x 118' or 500,000 gallon pond.
Step 1
You will need a dozer (D4- D8) caterpillar range and possibly a backhoe.

Step 2
First we stake a 118' x 118' area.
Then we take the dozer and push the dirt on the inside about 1ft deep to form the 5 foot tall berm forming all sides of the pond.

Step 3
Then we clean up the area with the bobcat and roller, compacting and forming the berm to a smooth surface ready for pond liner installation.

Step 4
Then we roll out and position the pond liner in pond area ready for welding together.

Step 5
To allow for settling we leave slack and wrinkles in the bottom of the pond liner while it fills up with water.

Pond Liner Specs
Pond Liners are 59' x 59' = approximately 150,000 gallons @ 6 foot depth.
100' x 59' = approximately 225,000 gallons @ 6 foot depth.

Custom Liners
Custom Liners such as 118' x 100' are Approximately 500,000 - 1,000,000 gallons.
Custom sized factory pre-seamed liners available for additional cost.

Material
Our nylon webbing reinforced elastomeric rubberized nylon liners are ten times the tensil strength and puncture resistant compared to EPDM liners. The need for Geotextile underlayment, carpet or clay has been decreased with the use of our superior strength liners. Only unraked, extremely rocky areas need to be covered with underlayment. Other liners need to go over extremely smooth surfaces. Pond liner 59' x 59' or 118' x 100' with 4 each 59' x 59' liners bonded together, extremely durable; can hold up to approximately 500,000 - 1,000,000,000 gallons! Single pond liners 59' x 59' can hold approximately 150,000 gallons. Far superior to rubber membranes — see below.

Originally designed as a fuel spill berm liner for the US military, it has been manufactured to tight MIL specs. Elastomeric coated nylon webbing is extremely tear and puncture resistant, and is designed for prolonged UV exposure. The outer edges feature doubled material and eight handle loops, each designed to hold up to at least 500 pounds of pulling force.

TESTIMONIAL:
I have had rubber pond liners myself in Central Oregon, a high desert area, and was surprised at how easily they tore when deer veered into the pond. So, I looked up the specs for pond liners online and came across those for one of the leading materials, the Firestone EPDM membrane.

I am more of a scientist myself, than a salesman. There is no doubt in my mind that my liners, made of an elastomeric coated nylon webbing, are far more tear resistant and durable than any rubber membrane could be not only in theory, but also in practice; see for example the description of the ‘screwdriver test’ below.
In the worst case, damage will likely result in much smaller holes than in rubber, which can simply keep on tearing. Also, damage can be repaired either with a specified combination of heat and pressure, or simply by compressing a plug over the hole, or oftentimes temporarily by plugging it with a wooden plug.

The military has very practical tests for specifying puncture resistance: One of them is forcing a screwdriver through the material. The specifications for the ‘screwdriver test’ on this material require a puncture resistance of 10 times the tensile strength of the Firestone membrane!

The edges of my liners have doubled up material: it is folded over and heat-seamed. The tear resistance specs for the seams alone are equal to the tear resistance of an untouched piece of the Firestone liner; the fabric itself is many times more tear resistant.
New/old stock, meaning it has been sitting on the shelf for a while, still in sealed crate, never used.
