Ponds need Pond Liners like a building needs a foundation. Among all the materials used for Pond Liners, plastic is the most versatile. It comes in two forms- pre-formed and flexible.
Preformed or rigid plastic liners are strong and long-lasting. They are made of polythene and other recycled plastic material. They do not develop leaks. They are more cost-effective than concrete. An average gardener can set up a small pond within one day using this liner.
Some of these models are fitted above the ground and some below the ground. Rocks and stones may be placed around it to give a natural look. The liners may be both UV- as well as frost-resistant. But they may be difficult to fit because of their different shapes and sizes.
Among the preformed models, the plastic liners may be cheaper than fiberglass, but do not offer support for free-standing use of the pond in a raised water garden. It is difficult to build around a plastic pond and support it evenly. When support is not uniform there is a danger that the plastic liner will crack.
Flexible Pond Liners are also available, like PVC (Poly Vinyl Chloride) and HDPE (High Density Poly Ethylene).These liners are not as flexible as rubber. Plastic liners are often used on large holding ponds when economy is a bigger concern than flexibility.
Large ponds require a Pond Liner that is safe for fish and aquatic plant life, inexpensive, easy to install and durable. Polyethylene fits the bill. Medium-density Polyethylene contains up to 5 percent carbon black, which makes it highly UV stable and suited to outdoor life. Twenty and 30 mm polyethylene can be custom-made according to your specifications.
PVC, or Polyvinyl Chloride, has excellent chemical compatibility and puncture resistance, lending itself to membrane liner applications. Some PVC liners contain UV stabilizers which protect them from breaking down when exposed to sunlight. PVC is not a crystalline membrane liner material, so it can elongate in all directions. It is the most cost-effective buried membrane and it has the longest successful use of liner material.
Another plastic is Polypropylene. It has special properties, like outstanding dimension stability, low coefficient of expansion and contraction, wide temperature seaming range, good chemical resistance and no stress cracking.
Plastic has its plusses and minuses, and the choice depends on the individual's requirements.
Plastic is one of the most versatile materials in the market that you can use in a wide variety of applications. The use of plastic ranges from making of children's toys to medical applications. Plastic sheets are one of the most common types of plastics that you will come across. Just like the other plastic materials, they have a wide range of applications. When buying them you need to consider a number of factors such as:
Different sizes of PVC have different uses. When making the purchase you should note that the thicker the plastic, the more expensive it is. The different thicknesses that you have to choose from include:
Light duty: These are 86 micron units that you use in protecting your paintings, furniture, and small home appliances.
Medium duty: They are 125-micron units you use to protect furniture. You can also use the plastic to store and transit furniture. Experts have also shown that they are highly effective in ground warming.
Heavy duty: Heavy duty plastics are 250 microns in size and ideal for weatherproofing, ground warming, wall covers, lawn care, and duty transit.
To get the most from your PVC sheet, you need to get the right thickness. If you will be using the unit outdoors, especially on the ground, you should go for one that is at least medium duty.
In addition to the color being a matter of personal preference, different colors are ideal for different applications. Clear polyethylene sheets are a great choice when you are interested in natural lighting. These sheets have great applications during home repairs and construction. You can also use them in creating walls and roots in greenhouses.
Black sheets are opaque and block most of the light. Just like their clear counterparts, they have wide applications in covering furniture and floor. There are some people that buy them in order to block light from reaching unwanted areas. Black sheets are heavily used in the agricultural setting where they are used to retain ground and keep weeds out.
These are two of the main factors that you should consider when buying PVC sheets. When making the purchase, consider the size of the sheet that you want. This should be informed by the area you want to use them. Also, pay close attention to the quality of the sheets. Just like when buying any other material, go for the highest quality of PVC that you can afford.
