What do Liners do and How do They Work?

Anyone who is familiar with spill containment will tell you that Liners play an absolutely crucial role in spill containment and environmental protection. Used in a variety of applications, they are instrumental in preventing leaks, seepage, and contamination by acting as a reliable barrier between hazardous substances and the surrounding environment. In this blog we will take you through the specifics of what liners do, how they work, and why they are an essential component of effective bunding solutions.

What Are Liners Used For?

Liners are commonly used in industrial, commercial, and environmental settings to contain liquids and prevent them from escaping into the soil or water systems and then causing environmental damage. They are widely applied in:

• Secondary containment systems: Providing an additional layer of protection in bunded areas where hazardous liquids are stored.

• Landfills: Preventing leachate (the pollution-causing liquid that drains from a landfill) from contaminating groundwater.

• Storage tanks and reservoirs: Protecting against leaks and corrosion.

• Ponds and lagoons: Containing water or chemicals safely.

  
  

By acting as a protective layer, liners ensure compliance with environmental regulations and help businesses mitigate the risks associated with spills and leaks, like creating workplace hazards or causing pollution.

How Do Liners Work?

Liners function by creating an impermeable (or highly resistant) barrier between a stored liquid and the surface beneath it. They are specially designed to withstand chemical exposure, mechanical stress, and environmental factors such as temperature fluctuations and UV radiation. Their effectiveness can depend on the material used, installation method, and maintenance practices, so these are important factors to consider.

What Are Liners Made Out Of?

Liners are manufactured from a variety of materials, each suited to specific applications. Here are some examples, each with their unique attributes:

• High-Density Polyethylene (HDPE): Known for its durability, chemical resistance, and long lifespan.

• Low-Density Polyethylene (LDPE): More flexible than HDPE, often used in applications requiring adaptability.

• Polyvinyl Chloride (PVC): Lightweight and cost-effective, but less resistant to harsh chemicals.

• Reinforced Geotextile Liners: Offer additional strength and puncture resistance, ideal for heavy-duty applications.

  
  

How Are Liners Installed?

Properly installing a liner is key to ensuring that it performs effectively and does the best job possible. Depending on the type and size of the liner, installation can involve the following:

• Seam welding: Using heat or chemical bonding to create a continuous, watertight barrier.

• Anchoring systems: Securing the liner in place to prevent movement or damage.

• Protective layers: Placing a geotextile underlay beneath the liner to reduce the risk of punctures.

  
  

It’s also important to regularly maintain liners by regularly inspected for damage, wear, or chemical degradation. Any identified issues should be repaired promptly to prevent leaks or failures.

Why Are Liners So Essential for Spill Containment?

Liners are undoubtedly a vital part of any spill containment system, providing businesses with a reliable way to prevent environmental contamination and ensure regulatory compliance. Their ability to act as a secure barrier against leaks and spills makes them indispensable for industries dealing with hazardous substances.

For businesses seeking high-quality bunding solutions, selecting the right liner is essential to achieving long-term containment success.
