WATER TANK LINERS

SELECTING THE RIGHT MATERIAL

· ·

When it comes to lining a pond, the first and more popular option is a flexible liner made from Reinforced Polyethylene, Reinforced Polypropylene, CSPE, PVC or EPDM Rubber.  There are other cheaper materials available; however for the purpose of building a lasting pond, it is advisable to use one of these flexible materials.

Reinforced Polyethylene (RPE) Liners

Reinforced polyethylene liners are generally considered the most durable liners available. In many cases, RPE liners don’t require a protective underlayment because of their higher tensile strength. Another advantage of reinforced polyethylene is they can be produced in very large sizes because of their light weight.  However, a possible disadvantage to a RPE liner is that the material is slightly stiffer to work with which is only a problem if the pond has a lot of sharp protrusions, bends or corners or pipe penetrations.

Reinforced Polypropylene (RPP) Liners

Reinforced polypropylene liners are generally used for potable water applications.  RPP can be easily box-welded into 3D shapes.  Box-welding is the process of taking a flat liner and creating a 3D shaped box through the process of heat welding the seams. The main advantage of box-welding is that all the corners are nice and clean with no folds or wrinkles. If you’ve ever worked with a flat liner like EPDM rubber and tried to bend it around corners and ledges, you’ll know that you will never get it completely flat. RPP is the preferred material if a pond has pipe penetrations.  It also has an extremely long life-span.

Chlorosulfonated Polyethylene (CSPE) Liners

Chlorosulfonated Polyethylene liners are geomembranes formerly known as Hypalon. CSPE or HypaFlex is a high-performance material designed for long-term applications, including floating covers and exposed liners. CSPE provides truly outstanding UV protection and long-term performance. HypaFlex is backed with an industry-leading 30-year weathering warranty.

PVC Liners

PVC liners are usually the least expensive option compared to other flexible liner materials, but their biggest downside is their lack of UV stability. What that means is that the pond liner must be completely buried with no direct sunlight contact; otherwise, the liner will begin to break down, shortening the life span.

EPDM or Rubber Liners

EPDM rubber liners are quite heavy.  They are typically quite UV resistant which is a definite plus over some PVC liners. As a fishpond liner, EPDM is a good choice due to the lack of plasticizers in the liner. It is also possible to join two or more sheets together with some pond liner tape.  In the case of large pond liners, it is often essential to combine multiple sheets to create a liner in the desired shape and size. Because rubber is so much heavier than material mentioned above, it is often more difficult to find and ship large pieces of EPDM due to weight concerns. If you need a large piece, it might be better to go with an RPE liner since it’s stronger, lighter and more cost effective.

LEAKY WATER TANKS

· ·

The US uses 322 billion gallons of water a day. Across the country, hundreds of water tanks are used to store accessible water for both personal and commercial use. Food and beverage preparation, household use, agriculture and irrigation, fire suppression, and industrial manufacturing are the most common uses.

By the end of this article, you’ll gain more insight into:

  • Why a water storage tank leaks
  • Options to repair a leaky tank
  • How to prevent leakage in a water tank

Why a water storage tank leak

There are several reasons a water storage tank may leak. Some of the most common reasons include corrosion, continual overfilling or excessive pressure, piping failure, and lack of proper maintenance.

Corrosion

Naturally, over time, especially when not properly maintained, things begin to corrode. Deterioration of water storage tanks becomes most prevalent when exposed to extreme changes in natural elements.

Overflow and excessive pressure

When water storage tanks are built, they are designed to hold a particular amount of pressure. When that pressure exceeds that threshold, trouble happens. A continual overfilling of water can also cause additional wear on the tank speeding up the eventual deterioration process.

Piping failure

In addition to the storage tank itself, the pipes that provide input and output of water, need maintenance and replacement over time. Pipes and their connecting fittings deteriorate allowing for brittleness and cracks. One corroded pipe can cost thousands of dollars worth of damage.

Improper maintenance

Poor upkeep of a water storage tank can cause leakage. Not replacing fuel filters, pipes, and addressing the wear and tear of the tank itself (both inside and out), can bring a slew of issues.

Options to repair a leaky tank

If you’re reading this article searching for a solution to replacing a water storage tank, you’ve come to the right place. Water storage tanks that have begun to leak are fixable. Here are a few options.

Water tank liners

One of the most cost-saving ways to repair a water tank leak is through the use of a custom-fabricated, industrial-grade water tank liner. These liners are a less costly alternative to tank replacement or tank coating. Liners from Carson Manufacturing contain no solvent or glue and require minimal downtime. They are durable and long-lasting and go through rigorous inspection and testing.

Water tank coating

Depending on the type and external conditions of the water tank, a fluorourethane, polysiloxane, ceramic, or epoxy coating may be suitable. It is crucial to select an application that is conducive to the usage of the tank.

How to prevent leakage in a water tank

Most seeking solutions to water storage tank leaks are probably doing so in a reactive state. However, preventing leakage before it happens is best.

Here are a few ways you can prevent first-time or continual leaks in water storage tanks.

  • Add a water tank liner: Before the leak starts, consider adding a water tank liner. This liner acts as a second tank and can long preserve the life of the tank itself.
  • Maintenance: Staying on top of regular maintenance is crucial to prevent leaks in all water storage tank components.
  • Don’t be excessive: Don’t overfill tanks, and don’t add unnecessary pressure.
