Howdy clg2stuff,

 

There are more than one way to make a pond. Making a form from concrete requires you first create a plan first and this will also be part of the budget. Next you would need to find out what the requirements that your local building authority has..if any.


This is important because of; gas, water, and communication lines that may be buried in the spot you have chosen to make your pond. Next you would need to have the area excavated so that a cement form could be made of the area. You would also have to have a cement mixer truck to drop the amount of cement you would need. Of course if you plan on making a small pond you could mix up the cement in a wheelbarrow. Here is a list of ideas by our very own Ingar:

 

Creating a water garden can be therapeutic and become that finishing touch that your yard has been looking for. The Home Depot has everything you need to make that pond of your dreams a dream come true. Here are some things to know to help inform you, to ensure you get the best pond for you.

Water gardens can be a lovely addition to your backyard, and the key to successful installation is choosing the right liner. Pond liners are the most versatile way to build a pond, and there are many varieties to choose from, depending upon your climate, the location of your water garden and your budget. Choosing a quality liner is also important for keeping aquatic life healthy. Some homeowners think they can make do with swimming pool liners or heavy plastic sheeting; however, these products break down over time, puncture easily and can prove toxic to fish and plants. Before shopping for a water garden liner, consider the following questions:

*  Are you building a water garden in a warm or cold climate?

*  Will your water garden be in direct sunlight or partial shade?

*  Is cost or quality your primary consideration?

*  What size liner do you need for your pond?

*  Do you prefer a liner that is easier to install? 

Types, Materials and Liner Calculations

When planning your water garden, you'll want to choose a liner that allows you to create exactly the pond you desire. With such a wide variety of types and materials to choose from, you're sure to find the right match for your needs. Selection is largely determined by the size and shape of the pond, your budget and climate. Flexible liners offer extra versatility while preformed liners provide an established structure to work with. Concrete liners are also another option, though they require professional installation to prevent cracking. Once you decide on a pond size, you'll need to take measurements to ensure you bring home the right size liner.

 

Flexible Liners: Flexible liners are a lightweight plastic or rubber material that can be cut into any desired shape. They are ideal for building oversized or uniquely shaped ponds. Flexible liners can be used for both small and large ponds alike and are incredibly easy to install. There are three general types, including EPDM (ethylene propylene diene monomer), PVC (polyvinyl chloride) and butyl rubber. These types are available in premeasured sheets and rolls. Most of these liners are manufactured in colors that reflect the natural look of a real pond, such as neutral earth tones of brown, green and black, which can give your pond a sense of depth.

*  When creating large and oversized ponds, flexible liners are the best choice.

*  Flexible liners make it easy to match unique ledges or zones created when digging the hole.

*  Flexible liners are often less expensive than preformed or concrete liners.

*  When properly installed, flexible liners can last for many years.

 

Preformed Liners: For definite shape and size, preformed liners are a good bet, although they often require more installation time because a hole must be excavated to match the liner design. Preformed liners are usually constructed of a strong plastic, such as HDPE (high-density polyethylene) or fiberglass and are easy to install. Although you can find liners that are as large as 12' across, the majority are smaller -- around 3' to 6' across and 18" deep. Because preformed liner ponds tend to be smaller and shallower, watch out for fluctuating water temperatures and low oxygen levels if you have fish. Also, if you live in cold climates, a shallow liner may make it impossible for fish or other aquatic animals to survive outside in the winter, since ponds must be located at least 1' below the freezing line to permit survival. Reinforce the pond's top edge, as rocks or paving that rest on the edge can crack it.

*  Available in a variety of shapes and sizes, making it easy to visualize your finished pond.

*  Some preformed ponds offer "planning shelves" to create the natural look of a pond with various slopes.

*  Plastic liners tend to be less costly than units that are constructed of fiberglass.

*  Although expensive, fiberglass ponds can be designed and manufactured according to specification, for easier installation.

 

Concrete Liners: Concrete ponds are made of a mix of cement, sand, gravel and water. Weather is a critical factor when mixing the concrete, as freezing conditions will make the concrete disintegrate before it cures. Likewise, hot weather may dry it too quickly, which can also cause concrete to fall apart. Concrete ponds require reinforcing mesh, rods or expansion joints for large areas or steep sides. These reinforcements are actually buried within the concrete to improve structural integrity.

 

*  In general, concrete ponds are more expensive, requiring footings, reinforcements and several inches of concrete.

*  Concrete ponds may last longer than other types; however, they can develop cracks within a few years.

*  Larger concrete ponds usually require help from a professional.

*  Concrete ponds tend to have a higher pH, which can contribute to greater algae growth.

*  Concrete takes time to set so allow up to two weeks to let it cure completely.

 

Liner Calculations: Once you decide on the size pond that you want, you are ready to calculate the liner size. Measure the length, width and depth of your pond. If you have an irregular shape, include the widest part of the shape as the width and the longest length for your measurements. Next add your measurements to the following formulas to figure out the size of liner that you need. The extra 6" allow sufficient quantities of liner to go under and behind the edging stones 

 

Water Garden Calculations
Liner lengthMaximum pond length + 2 x pond depth + 6"
Liner widthMaximum pond width + 2 x pond depth + 6"
Pond capacityLength x Width x Depth x 7.50 = Gallons (in. ft.)

 

Features

EPDM (Ethylene Propylene Diene Monomer): EPDM rubber performs well in colder climates. This highly flexible liner also resists air pollution and has a lifespan of 20 years. EPDM is also non-toxic to plants and fish and is stable when exposed to UV rays.

 

PVC (Polyvinyl Chloride): These liners are highly flexible, easy to work with and are UV stable if they are not exposed to direct sunlight. PVC liners last for about 10 years or more but are less resistant to freezing temperatures.

 

HDPE (High Density Polyethylene): HDPE liners are made from a tough thermoplastic substance that is safe for fish and plants. These liners are inexpensive and can last for up to 15 years. HDPE liners are the least flexible and do not work as well in colder climates. HDPE liners are generally less expensive than PVC liners.

 

Butyl Rubber: Butyl rubber liners are UV-resistant and last approximately 20 years. Some butyl liners can be toxic so do your research if you plan to have fish in your pond. Although somewhat flexible, these liners are thick and tough to fold at corners and curves.

 

Fiberglass: Fiberglass liners cost much more than flexible liners and are not as natural looking. Before setting a fiberglass pond in the ground, it is critical to use a thick layer of brick sand to pack under and around the pond.

 

Happy Gardening,
